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.

c63aeb38bb state: prepare for NEP-11 data tracking, refactor/rename
There is a lot of similarity, so try reusing common code and use more neutral
naming.

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).

9875799893 transaction: add new Rules witness scope
See neo-project/neo#2622. The implementation is somewhat asymmetric (and not
very efficient) for binary/JSON encoding/decoding, but it should be
sufficient.

ce549e4cb2 core/test: allow to determine system fee automatically
Eventually this will be replaced by `pkg/neotest` invocations but for
now it allows us to remove NNS constants together with the tests.

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).

75d7891ca1 services: add ability to combine notary signers
Notes for witnesses:
* [N sig + M multisig + K contract] combination is possible where N, M, K >=0.
* Each verification script should be properly filled in.
* Each invocation script should either be empty or contain exactly one
signature.

7ba88e98e2 core: optimize (*MemCachedStore).Seek operation
Real persistent storage guarantees that result of Seek is sorted
by keys. The idea of optimisation is to merge two sorted seek
results into one (memStore+persistentStore), so that
(*MemCachedStore).Seek will return sorted list. The only thing
that remains is to sort items got from (*MemoryStore).Seek.

191cc45032 core: sort items in MemoryStore.Seek
MemoryStore is used in a MemCachedStore as a persistent layer in tests.
Further commits suppose that persistent storage returns sorted values
from Seek, so sort the result of MemoryStore.Seek.

Benchmark results for 10000 matching items in MemoryStore compared to
master:
name          old time/op    new time/op    delta
MemorySeek-8     712µs ± 0%    3850µs ± 0%   +440.52%  (p=0.000 n=8+8)

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.

b66bc33cf9 native: short-circuit successive GAS distributions
GAS can only be distributed once in a block for particular address, so it

~33500.
