4c39b6600d *: store application long along with tx/block 
Two times less keys inserted into the DB per tx leads to ~13% TPS
improvement. We also drop one goroutine with it which isn't bad as well.

9576e10d04 storage: use map size hints to optimize subsequent persist() 
We're likely to have something comparable to the current changeset in the
subsequent one. If it's bigger, no big deal, it'll be reallocated, if it's
smaller, no big deal, the next one will be preallocated smaller.

748a70569a mempool: use uint256 library for fee tracking 
It's very effective in avoiding allocations for big.Int, we don't have a
microbenchmark for memppol, but this improves TPS metrics by ~1-2%, so it's
noticeable.

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.

f96d9d168e native/interop: use oracle request signers for oracle response witness 
Oracle responses must use the same set of signers as oracle requests even
though the transaction itself is signed by oracle nodes/contract.

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).

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).

part that remains. This implies that node with path matching `from` will
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.

b66bc33cf9 native: short-circuit successive GAS distributions 
GAS can only be distributed once in a block for particular address, so it
makes little sense trying to calculate it again and again. This fixes
neo-bench for NEO voter, because without it we get ~2500 TPS for
single-address test and with it it jumps 13-fold to normal values like
~33500.

We need to store NEO balance's LastUpdateHeight before GAS mint,
because mint can call onNEP17Payment and onNEP17Payment can call NEO
transfer which also calls GAS mint. Storing balance height allows to
avoid recursion.

regular MPT code and create a separate structure for this.

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.

2808f6857d interop: don't allocate for Functions and Notifications in New 
Functions are usually immediately replaced (and it's OK for them to be nil,
searching through an array with length of zero is fine), Notifications are
usually appended to (and are absolutely useless in verification contexts).

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.

291a29af1e *: do not use WriteArray for frequently used items 
`WriteArray` involves reflection, it makes sense to optimize
serialization of transactions and application logs which are serialized
constantly. Adding case in a type switch in `WriteArray` is not an
option because we don't want new dependencies for `io` package.

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.

3a93977b7b oracle: only process new requests after initial sync 
If an oracle node is resynchronized from the genesis the service receives all
requests from all blocks via AddRequests() invoked from the native
contract. Almost all of them are long obsolete and need to be removed, native
oracle contract will try to do that with RemoveRequests() calls, but they
won't change anything.

So queue up all "initial" requests in special map and manage it directly
before the module is Run() which happens after synchronization
completion. Then process any requests that are still active and work with new
blocks as usual.

233307aca5 stackitem: completely drop MaxArraySize 
Turns out C# VM doesn't have it since preview2, so our limiting of
MaxArraySize in incompatible with it. Removing this limit shouldn't be a
problem with the reference counter we have, both APPEND and SETITEM add things
to reference counter and we can't exceed MaxStackSize. PACK on the other hand
can't get more than MaxStackSize-1 of input elements.

Unify NEWSTRUCT with NEWARRAY* and use better integer checks at the same time.

Multisig limit is still 1024.

We have a lot of native contract types that are converted to stack items

io.Serializable code.

This also introduces to/from converter in testserdes which unfortunately
required to change util tests to avoid circular references.

9673a04009 core: allow to add several headers with StateRootInHeader on 
Problem: with StateRootInHeader setting on only one header of height N+1
can be added to the chain of height N, because we need local stateroot
to verify headers (which is calculated for the last stored block N).
Thus, adding chunk of headers starting from the current chain's heigh
is impossible and (*Blockchain).AddHeaders doesn't have much sense.

Solution: verify header.PrevStateRoot only for header N+1. Rest of the
headers should be added without PrevStateRoot verification.

might be cases when we need to get the balance that was updated
earlier during the same transaction processing.

edfca68a17 rpc: refactor invokecontractverify 
In `(c *Client) AddNetworkFee` we define network fee for contract
witness verification via `invokecontractverify` RPC call, and that's the
initial purpose of this RPC method. But it was not implemented
correctly. It used `System.Contract.Call` instead of beheiving like
`initVerificationVM`.

During real contract witness verification the whole contract's script is
loaded into VM, and then we jump to the `verify` method. Thus, to define
exact contract verification price, we should act like this (and not just
perform `System.Contract.Call` of `verify` method).

Tests are added.

This bug is the reason of adding extra GAS (c.notary.extraVerifyFee) to
pre-calculated value in
https://github.com/nspcc-dev/neofs-node/pull/404/files#diff-639db437ca2578db46c9e8cbf18f9aa01f8ca5aee30e0fa7e70ba0354822d7b3R237

8444f3d816 network: refactor notary service's PostBlock 
There was a deadlock while trying to finalize transaction during
PostBlock:
	1) (*Notary).PostBlock is called under the blockchain lock
	2) (*Notary).onTransaction is called inside the PostBlock
	3) (*Notary).onTransaction needs to RLock the blockchain to add
completed transaction to the memory pool (and the blockchain is Lock'ed
by this moment)

The problem is fixed by using notifications subsistem, because it's not
required to call (*Notary).PostBlock under the blockchain lock.
