8ec8511d9d core: remove mutexes and atomic values from native cache 
Native cache is always wrapped into independant layers, so concurrent
RW access is no-op.

7b632c8ee8 core: refactor natives cache 
1. Use layered natives cache. With layered cache the storeblock
process includes the following steps: create a wrapper over
current nativeCache, put changes into upper nativeCache layer,
persist (or discard) changes.
2. Split contract getters to read-only and read-and-change. Read-only
ones doesn't require the copy of an existing nativeCache item.
Read-and-change ones create a copy and after that change the copy.

9862b40f2c rpc: support InitialGasDistribution response from old Neo-Go nodes 
https://github.com/nspcc-dev/neo-go/pull/2435 breaks compatibility
between newer RPC clients and older RPC servers with the following
error:
```
failed to get network magic: json: cannot unmarshal string into Go struct field Protocol.protocol.initialgasdistribution of type int64
```

This behaviour is expected, but we can't allow this radical change.
Thus, the following solution is implemented:
1. RPC server responds with proper non-stringified
   InitialGasDistribution value. The value represents an integral
   of fixed8 multiplied by the decimals.
2. RPC client is able to distinguish older and newer responses. For
   older one the stringified value without decimals part is
   expected. For newer responses the int64 value with decimal part
   is expected.

The cludge will be present in the code for a while until nodes of
version <=0.98.3 become completely absolete.

a2126b92e1 rpc/server: only log errors during Shutdown 
Sending them down the errChan is not really helpful and it can lead to
deadlock. If an error happens during node shutdown, we're exiting anyway, if
it happens during service restart, the old server will be dead irrespective of
this error (if this affects new one in any way we'll know it soon).

We shouldn't use StoragePrice from Blockchain because its dao doesn't

each transaction and retrieve the price from cached DAO.

91a4bc5beb core: use proper DAO to get ExecFeeFactor 
The usage of the Blockchain's one leads to the same ExecFeeFactor within
a single block. What we need is to update ExecFeeFactor after each
transaction invocation, thus, cached DAO should be used as it contains
all relevant changes.

a8d2df874f stackitem: limit JSON size in ToJSONWithTypes 
Also do not limit depth. It was introduced in e34fa2e915 as a simple
solution to OOM problem. In this commit we do exactly the refactoring
described there. Maximum size is the same as stack item size and
can be changed if needed withouth significat refactoring.
`1 MiB` seems sufficient, though.

1. Move redirections check to the tcp level. Manually resolve request address
and create connection for the first suitable resolved address.
2. Remove URIValidator. Redirections checks are set in the custom http client,
so the user should take care of validation by himself when customizing the
client.

0092330fe1 rpc: carefully review places where Client.cache.initDone is used 
1. Keep initDone check only for the places where cache is directly accessed.
   We don't need to check it in other places, otherwise we have a mess of
   duplicating checks.
2. Fix bug in code related to block deserialisation. There's no magic, so
   checking that initialisation is done is not enough for proper block
   deserialisation. We need to manually fill StateRootEnabled field.
3. Since transaction doesn't need network magic to compute its hash, we don't
   need to perform Client initialisation before transaction-related requests.
4. Check that cache is initialised before accessing network magic.
5. Refactor the way Policy contract hash is fetched for Client requests.
   We don't really need Client initialisation for that, it's OK to fetch Policy
   hash on-the-fly.

9bfb3357f2 storage: add "private" mode to MemCachedStore 
Most of the time we don't need locking on the higher-level stores and we drop
them after Persist, so that's what private MemCachedStore is for.

It doesn't improve things in any noticeable way, some ~1% can be observed in
neo-bench under various loads and even less than that in chain processing. But
it seems to be a bit better anyway (less allocations, less locks).

It's very special, single-purpose thing, but it improves cumulative time spent
in GC by ~10% for LevelDB and by ~36% for BoltDB during 1050K mainnet chain

disks the difference might be more noticeable.

423c7883b8 core: implement basic GC for value-based storage scheme 
The key idea here is that even though we can't ensure MPT code won't make the
node active again we can order the changes made to the persistent store in
such a way that it practically doesn't matter. What happens is:
 * after persist if it's time to collect our garbage we do it synchronously
   right in the same thread working the underlying persistent store directly
 * all the other node code doesn't see much of it, it works with bc.dao or
   layers above it
 * if MPT doesn't find some stale deactivated node in the storage it's OK,
   it'll recreate it in bc.dao
 * if MPT finds it and activates it, it's OK too, bc.dao will store it
 * while GC is being performed nothing else changes the persistent store
 * all subsequent bc.dao persists only happen after the GC is completed which
   means that any changes to the (potentially) deleted nodes have a priority,
   it's OK for GC to delete something that'll be recreated with the next
   persist cycle

Otherwise it's a simple scheme with node status/last active height stored in
the value. Preliminary tests show that it works ~18% worse than the simple
KeepOnlyLatest scheme, but this seems to be the best result so far.

Fixes #2095.

c4ee310e85 mpt: modify refcounted storage scheme to make GC possible 
Add "active" flag into the node data and make the remainder modal, for active

It is a simple wrapper over `CompileWithOptions` which we don't really
need. Custom options can be specified explicitly instead of using some
random default. This default was introduced in 1578904da, however tests

9b841b9b8f core, rpc: use Seek to iterate over NEP* transfers 
The results are controversial a bit. MemoryPS is a special storage
and the new approach doesn't help it to iterate through NEP17 transfers.
However, on long distances (if transfers are requested for more than
1000 blocks, which is ~4.1 hours of mainnet chain) both LevelDB and
BoltDB perform good enough with the new approach. Taking into account
the fact that default value for the query period of `getnep17transfers`
RPC handler is a week (~40K mainnet blocks) we can sacrifice MemoryPS
performance in favour of BoltDB and LevelDB optimisation.

Close #2263.

cd42b8b20c core: allow early Seek stop 
This simple approach allows to improve the performance of
BoltDB and LevelDB in both terms of speed and allocations
for retrieving GasPerVote value from the storage.
MemoryPS's speed suffers a bit, but we don't use it for
production environment.

Part of #2322.

6b105e6d10 neotest: use validators account instead of committee to pay the bills 
GAS and NEO tokens are sent to validators account (not the committee's
one). For single-node chain they are the same, but for four-nodes chain
they are different. Thus, use validators multisig address to create new
accounts and to deploy contracts.

Also, allow to provide desired account balance while creating new
account.

2c46b81864 native: optimize gas per vote calculation 
GAS per vote records are being returned from Seek in ascending way, and
we need the last record before the specified index which is close to
the current chain's height (most of the time). To optimize we can
iterate backwards strting from the last record using SeekBackwards.

ffb6504f67 vm: cut trailing spaces in PrintOps 
When there is a single big instruction (like PUSHDATA4) in script,
all other instructions are padded to the right with spaces.
This makes it hard to view script in terminal, because long lines
are usually wrapped at the screen boundary and printed as multiple lines.

The culprit is our `cursor` field which is printed in the last column
and causes all previous fields to have the same length for every
instruction. One way to fix this is to omit cursor field if it is empty.

37ecf51d13 neotest: allow to extract simple signers from multi-signer 
There is a quirk related to ordering: we store accounts in such an order that
is expected by multi-signature verification script. This was done to
speed up transaction/block signing which is done quite frequently in
tests. This commit allows to provide accounts in any order and to
extract a single signer from multi-signer based on this order.

1d1538c566 services: fix Oracle response transaction creation 
Problem: transactions with wrong hashes are accepted to the chain if
consensus nodes are designated as Oracle nodes. The result is wrong
MerkleRoot for the accepted block. Consensus nodes got such blocks
right from the dbft and store them without errors, but if
non-consensus nodes are present in the network, they just can't accept
these "bad" blocks:
```
2021-11-29T12:56:40.533+0300	WARN	blockQueue: failed adding block into the blockchain	{"error": "invalid block: MerkleRoot mismatch (expected a866b57ad637934f7a7700e3635a549387e644970b42681d865a54c3b3a46122, calculated d465aafabaf4539a3f619d373d178eeeeab7acb9847e746e398706c8c1582bf8)", "blockHeight": 17, "nextIndex": 18}

This problem happens because of transaction hash caching. We can't set
transaction hash if transaction construction wasn't yet completed.

5fbe838fd4 core: add and use synchronous persist to avoid OOM 
b9be892bf9 has made Persist asynchronous which
is very effective in allowing the system to continue processing
blocks/transactions while flushing things to disk. It at the same time is very
dangerous in that if the disk is slow and it takes much time to flush KV set
(more than persisting interval), there might be even bigger new KV set in
MemCachedStore by the time it finishes. Even if the system immediately starts
to flush this new data set it (being bigger) can take more time than the
previous one. And while doing so a new data set will appear in memory,
potentially again bigger than this.

So we can easily end up with the system going out of control, consuming more
and more memory and taking more and more time to persist a single set of
data. To avoid this we need to detect such condition and just wait for Persist
to really finish its job and release the resources.

5b470f14cc rpc: pass single Param to CreateFunctionInvocationScript 
N3 contracts require method and array of arguments to function correctly, but
CreateFunctionInvocationScript can produce scripts that won't work correctly
if one is to pass anything but a single array parameter to it. This doesn't
make much sense, so we can always expect there to be an array of parameters in
the third positional invokefunction argument (the same way C# node does).

Oracle responses must use the same set of signers as oracle requests even

We can probably improve interop.Context by removing Tx field completely and
adding more functionality to Container, but it's not very convenient for
VerifyWitness and will require adding more stub-like methods for Block, so Tx
is used for now (and we do have it in every relevant case).

db99368e96 compiler: optimize GAS cost of type conversion 
CONVERT call base price is 8192. DUP, ISTYPE and JMPIF all cost 2. So we add
0.07% overhead in the worst case and save 99.93% otherwise.

At the same time, old code was just two bytes and new one is seven, but I
think it's tolerable considering how much GAS it can potentially save.

8bb1ecb45a network: remove priority queue from block queue 
Use circular buffer which is a bit more appropriate. The problem is that
priority queue accepts and stores equal items which wastes memory even in
normal usage scenario, but it's especially dangerous if the node is stuck for
some reason. In this case it'll accept from peers and put into queue the same
blocks again and again leaking memory up to OOM condition.

Notice that queue length calculation might be wrong in case circular buffer
wraps, but it's not very likely to happen (usually blocks not coming from the
queue are added by consensus and it's not very fast in doing so).

Set all necessary context before file traversal, not only import

processed via `For*` iterators which set necessary context.
We can also refactor this a bit to have all context in one place,
this will be done in #2086.

also be included in the result, so additional check needs to be added to
the callback function.
2. Pass `path` and `from` without search prefix. Append prefix to the
result inside the callback.
3. Remove duplicating code.

(*Trie).Find changes:
1. Properly prepare `from` argument for traversing function. It closly
depends on the `path` argument.

c009356b73 core: simplify component flushing in storeBlock 
Instead of flushing everything to `cache` and then to `bc.dao`, wrap `bc.dao`
directly for block/tx data and AERs and then flush to it. Block/transactions
are usually processed more quickly than other components, so they easily end
up in `cache` where they directly affect Seek performance for any executing
transaction.

Simple as it is this change improves voter NEO transfer benchmark with 1000
accounts by more than 25%, from ~18500 TPS to ~23500 TPS. It doesn't affect
much other cases.

c465b18cb2 rpc: return protocol parameters in getversion, fix #2160 
`StateRootInHeader` is duplicated similarly to `Network`.
It will be removed in future as it is surely a protocol parameter.

In this commit:

1. Request unknown MPT nodes from peers. Note, that StateSync module itself
shouldn't be responsible for nodes requests, that's a server duty.
2. Do not request the same node twice, check if it is in storage
already. If so, then the only thing remaining is to update refcounter.

a22b1caa3e core: implement MPT Billet structure for MPT restore 
MPT restore process is much simpler then regular MPT maintaining: trie
has a fixed structure, we don't need to remove or rebuild MPT nodes. The
only thing we should do is to replace Hash nodes to their unhashed
counterparts and increment refcount. It's better not to touch the
regular MPT code and create a separate structure for this.

f721384ead core: allow empty MPT Leaf values 
Allow it for (*Trie).Put. And distinguish empty value and nil value for
(*Trie).PutBatch, because batch is already capable of handling both nil
and empty value. For (*Trie).PutBatch putting nil value means deletion,
while putting empty value means just putting LeafNode with an empty
value.

217d7bdf44 keys: add equality benchmark 
Go 1.15 provides native (*ecdsa.PublicKey).Equal method, but we can't drop our
own Equal because the types are different and there is still code using our
Equal (forcing it to convert types is counterproductive), while changing
(*PublicKey).Equal to use (*ecdsa.PublicKey).Equal internally with some kind of

  (*ecdsa.PublicKey)(p).Equal((*ecdsa.PublicKey)(key))

slows it down:

930653418d vm: rework stack as a simple slice 
Double-linked list is quite expensive to manage especially given that it
requires microallocations for each Element. It can be replaced by simple slice
which is much more effective for simple push/pop operations that are very
typical in a VM. I've worried a little about more complex operations like
XDROP/1024 or REVERSEN/1024 because these require copying quite substantial
number of elements, but turns out these work fine too.

At the moment Element is kept as a convenient wrapper for Bytes/BigInt/Bool/etc
methods, but it can be changed in future. Many other potential optimizations
are also possible now.

a68a8aa8fc core: simplify and correct notification handling 
* both 'to' and 'from' are either Null or Hash160, there is no other
   possibility for valid NEP-17. So returning util.Uint160{} in case of
   parsing error is wrong.
 * but this is what allowed burns/mints to work at the expense of error
   allocation inside of util.Uint160DecodeBytesBE()
 * Uint160 can technically fit into regular VM integer, so even though it'd be
   quite surprising to see it there, TryBytes() is more correct (and easier!)
   to use
 * same thing with `amount`, we have `TryInteger()` that easily covers all
   possible cases and does appropriate error checking inside

ae071d4542 storage: introduce PutChangeSet and use it for Persist 
We're using batches in wrong way during persist, we already have all changes
accumulated in two maps and then we move them to batch and then this is
applied. For some DBs like BoltDB this batch is just another MemoryStore, so
we essentially just shuffle the changeset from one map to another, for others
like LevelDB batch is just a serialized set of KV pairs, it doesn't help much
on subsequent PutBatch, we just duplicate the changeset again.

So introduce PutChangeSet that allows to take two maps with sets and deletes
directly. It also allows to simplify MemCachedStore logic.

7bb82f1f99 network: merge two loops in iteratePeersWithSendMsg, send to 2/3 
Refactor code and be fine with sending to just 2/3 of proper peers. Previously
it was an edge case, but it can be a normal thing to do also as broadcasting
to everyone is obviously too expensive and excessive (hi, #608).

On a network with 4 CNs and 1 RPC node there is 1/256 probability that a block
won't be broadcasted to RPC node, so it won't see it until ping timeout kicks
in. While it doesn't see a block it can't accept new incoming transactions so
the bench gets stuck basically. To me that's an acceptable trade-off because
normal networks are much larger than that and the effect of this patch is way
more important there, but still that's what we have and we need to take into
account.

966a16e80e network: keep track of dead peers in iteratePeersWithSendMsg() 
send() can return errStateMismatch, errGone and errBusy. errGone means the
peer is dead and it won't ever be active again, it doesn't make sense retrying
sends to it. errStateMismatch is technically "not yet ready", but we can't
wait for it either, no one knows how much will it take to complete
handshake. So only errBusy means we can retry.

So keep track of dead peers and adjust tries counting appropriately.

119b4200ac network: add fail-fast route for tx double processing 
When transaction spreads through the network many nodes are likely to get it
in roughly the same time. They will rebroadcast it also in roughly the same
time. As we have a number of peers it's quite likely that we'd get an Inv with
the same transaction from multiple peers simultaneously. We will ask them for
this transaction (independently!) and again we're likely to get it in roughly
the same time. So we can easily end up with multiple threads processing the
same transaction. Only one will succeed, but we can actually easily avoid
doing it in the first place saving some CPU cycles for other things.

Notice that we can't do it _before_ receiving a transaction because nothing
guarantees that the peer will respond to our transaction request, so
communication overhead is unavoidable at the moment, but saving on processing
already gives quite interesting results.

7fc153ed2a network: only ask mempool for intersections with received Inv 
Most of the time on healthy network we see new transactions appearing that are
not present in the mempool. Once they get into mempool we don't ask for them
again when some other peer sends an Inv with them. Then these transactions are
usually added into block, removed from mempool and no one actually sends them
again to us. Some stale nodes can do that, but it's not very likely to
happen.

At the receiving end at the same time it's quite expensive to do full chain
HasTransaction() query, so if we can avoid doing that it's always good. Here
it technically allows resending old transaction that will be re-requested and
an attempt to add it to mempool will be made. But it'll inevitably fail
because the same HasTransaction() check is done there too. One can try to
maliciously flood the node with stale transactions but it doesn't differ from
flooding it with any other invalid transactions, so there is no new attack
vector added.

f78bd6474f network: handle incoming message in a separate goroutine 
Network communication takes time. Handling some messages (like transaction)
also takes time. We can share this time by making handler a separate
goroutine. So while message is being handled receiver can already get and
parse the next one.

It doesn't improve metrics a lot, but still I think it makes sense and in some
scenarios this can be more beneficial than this.

8277b7a19a core: don't spawn goroutine for persist function 
It doesn't make any sense, in some situations it leads to a number of
goroutines created that will Persist one after another (as we can't Persist
concurrently). We can manage it better in a single thread.

This doesn't change performance in any way, but somewhat reduces resource
consumption. It was tested neo-bench (single node, 10 workers, LevelDB) on two
machines and block dump processing (RC4 testnet up to 62800 with VerifyBlocks
set to false) on i7-8565U.

b9be892bf9 storage: allow accessing MemCachedStore during Persist 
Persist by its definition doesn't change MemCachedStore visible state, all KV
pairs that were acessible via it before Persist remain accessible after
Persist. The only thing it does is flushing of the current set of KV pairs
from memory to peristent store. To do that it needs read-only access to the
current KV pair set, but technically it then replaces maps, so we have to use
full write lock which makes MemCachedStore inaccessible for the duration of
Persist. And Persist can take a lot of time, it's about disk access for
regular DBs.

What we do here is we create new in-memory maps for MemCachedStore before
flushing old ones to the persistent store. Then a fake persistent store is
created which actually is a MemCachedStore with old maps, so it has exactly
the same visible state. This Store is never accessed for writes, so we can
read it without taking any internal locks and at the same time we no longer
need write locks for original MemCachedStore, we're not using it. All of this
makes it possible to use MemCachedStore as normally reads are handled going
down to whatever level is needed and writes are handled by new maps. So while
Persist for (*Blockchain).dao does its most time-consuming work we can process
other blocks (reading data for transactions and persisting storeBlock caches
to (*Blockchain).dao).

The change was tested for performance with neo-bench (single node, 10 workers,
LevelDB) on two machines and block dump processing (RC4 testnet up to 62800
with VerifyBlocks set to false) on i7-8565U.

It obviously uses more memory now and utilizes CPU more aggressively, but at
the same time it allows to improve all relevant metrics and finally reach a
situation where we process 50K transactions in less than second on Ryzen 9
5950X (going higher than 25K TPS). The other observation is much more stable
block time, on Ryzen 9 it's as close to 1 second as it could be.

49be753850 core: spread storeBlock actions to three goroutines 
Block processing consists of:
 * saving block/transactions to the DB
 * executing blocks/transactions
 * processing notifications/saving AERs
 * updating MPT
 * atomically updating Blockchain state

Of these the first one is completely independent of others, it can be done in
a separate routine easily. The third one technically depends on the second,
it just doesn't have data until something is executed. At the same time it
doesn't affect future executions in any way, so we can offload
AER/notification processing to separate goroutine (while the main thread
proceeds with other transactions).

MPT update depends on all executions, so it can't be offloaded, but it can be
done concurrently to AER processing. And only the last thing actually needs
all previous ones to be finished, so it's a natural synchronization point.

So we spawn two additional routines and let the main one execute transactions
and update MPT as fast as it can. While technically all of these routines
could share single DAO (they are working with different KV sets) benchmarking
shows that using separate DAOs and then persisting them to lower one actually
works about 7-8%% better. At the same time we can simplify DAOs used, Cached
one is only relevant for AER processing because it caches NEP-17 tracking
data, everything else can do just fine with Simple.

The change was tested for performance with neo-bench (single node, 10 workers,
LevelDB) on two machines and block dump processing (RC4 testnet up to 50825
with VerifyBlocks set to false) on i7-8565U. neo-bench creates huge blocks
with lots of transactions while RC4 dump mostly consists of empty blocks.

On Ryzen 9 we've got 12% better RPS, 13% better TPS with 12% CPU and 3% RAM
more used. Core i7-8565U changes don't seem to be statistically significant:
1.8% more RPS, 1.6% more TPS with about the same CPU and 8.5% less RAM
used. It also is 1% worse in DB restore time.

The result is somewhat expected, on a powerful machine with lots of spare
cores we get 10%+ better results while on average resource-constrained laptop it
doesn't change much (the machine is already saturated). Overall, this seems to
be worthwhile.

a429aa3e68 wallet: truncate file when writing 
If wallet size decreases, we need to remove trailing garbage if it
exists. This can happen when removing account or reading pretty-printed
wallet. It doesn't affect our CLI (we decode only file prefix), but
it is nice to always have a valid JSON file.
