7f40a0cfd8 state: prime token transfer info with the demand for new logs 
Setting NewNEPXXBatch avoids the need to get them from the database which is
useful for newly tracked accounts.

There is a lot of similarity, so try reusing common code and use more neutral

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).

65016e8070 core: fix data race in notary test 
I don't think it's possible with regular service functioning, but it happens
during testing because of pointer reuse:

very efficient) for binary/JSON encoding/decoding, but it should be
sufficient.

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).

7ba88e98e2 core: optimize (*MemCachedStore).Seek operation 
Real persistent storage guarantees that result of Seek is sorted

(*MemCachedStore).Seek will return sorted list. The only thing
that remains is to sort items got from (*MemoryStore).Seek.

Further commits suppose that persistent storage returns sorted values

master:

8e7c76827b core: optimise (*Billet).Traverse and (*Trie).Find 
(*Billet).Traverse changes:
1. Get rid of the `offset` argument. We can cut `from` and pass just the
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.

1. Request unknown MPT nodes from peers. Note, that StateSync module itself

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.

MPT restore process is much simpler then regular MPT maintaining: trie

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.

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

5f9d38f640 core: refactor (*DAO).StoreAsTransaction 
Squash (*DAO).StoreAsTransaction and
(*DAO).StoreConflictingTransactions. It's better to keep them this way,
because StoreAsTransaction is always followed by
StoreConflictingTransactions, so it's an atomic operation.

The logic wasn't changed.

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.
