7d6f087337 storage: drop (KeyPrefix).Bytes() API 
It allocates and most of the time we can avoid that.

7dc8fc443f dao: simplify buffer management for private DAO 
Private DAO is only used in a single thread which means we can safely reuse
key/data buffers most of the time and handle it all in DAO.

Doesn't affect any benchmarks.

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).

9d2ef775cf storage: simplify (*MemCachedStore).Put/Delete interface 
They never return errors, so their interface should reflect that. This allows
to remove quite a lot of useless and never tested code.

Notice that Get still does return an error. It can be made not to do that, but
usually we need to differentiate between successful/unsuccessful accesses
anyway, so this doesn't help much.

c4ee310e85 mpt: modify refcounted storage scheme to make GC possible 
Add "active" flag into the node data and make the remainder modal, for active
nodes it's a reference counter, for inactive ones the deactivation height is
stored.

Technically, refcounted chains storing just one trie don't need a flag, but
it's a bit simpler this way.

86cb4ed80f mpt: add the notion of MPT mode 
It directly affects the storage format, so it's important. ModeGC is not used
at the moment, but defined for future extensibility.

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.

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.

856385b106 dao: use custom storage prefix 
We use 2 prefixes for storing items because of state synchronization.
This commit allows to parametrize dao with the default prefix.

0aedfd0038 core: fix bug in MPT pool during Update 
We need to copy the result of `TryGet` method, otherwice the slice can
be modified inside `Add` or `Update` methods, which leads to
inconsistent MPT pool state.

0e0b55350a core: convert (*Blockchain).JumpToState to a callback 
We don't need this method to be exposed, the only its user is the
StateSync module. At the same time StateSync module manages its state by
itself which guarantees that (*Blockchain).jumpToState will be called
with proper StateSync stage.

should be removed from storage. After state sync is completed,
outdated blocks/transactions/AERs should also be removed.

3b7807e897 network: request unknown MPT nodes 
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.
