241d5f593e *: use methods of binary.AppendByteOrder where applicable 
We often use binary.PutUint*, but almost all these cases have preallocated
buffer of the size that matches exactly the desired one and use a single or
a couple of calls to PutUint*. Thus, I don't think that replacing
binary.PutUint* by AppendUint* will make things better for all these usages.

ee4b8f883b core: check signers of on-chained conflict during new tx verification 
During new transaction verification if there's an on-chain conflicting
transaction, we should check the signers of this conflicting transaction.
If the signers intersect with signers of the incoming transaction, then
the conflict is treated as valid and verification for new incoming
transaction should fail. Otherwise, the conflict is treated as the
malicious attack attempt and will not be taken into account;
verification for the new incoming transaction should continue.

This commint implements the scheme described at
https://github.com/neo-project/neo/pull/2818#issuecomment-1632972055,
thanks to @shargon for digging.

1c38b45074 core: don't always store all hashes in memory 
We're paging these hashes, so we need a previous full page and a current one
plus some cache for various requests. Storing 1M of hashes is 32M of memory
and it grows quickly. It also seriously affects node startup time, most of
what it's doing is reading these hashes, the longer the chain the more time it
needs to do that.

Notice that this doesn't change the underlying DB scheme in any way.

9a06995460 bigint: don't allocate in ToPreallocatedBytes 
Turns out, it's almost always allocating because we're mostly dealing with
small integers while the buffer size is calculated in 8-byte chunks here, so
preallocated buffer is always insufficient.

Fix StorageItem reuse at the same time. We don't copy when getting values from
the storage, but we don when we're putting them, so buffer reuse could corrupt
old values.

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).

anyway, so this doesn't help much.

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.
