b66f666267 core: ensure memcached Seek operation is properly cancelled 
PR #2495 is not enought, the problem is reproduced during dump restore
with the stacktrace attached down below.

The reason is that SeekAsync starts goroutine that performs Seek
operation over private MemCachedStore. The goroutine iterates over
MemCachedStore's map without holding the lock (it's OK, because it's
private), whereas the main thread continues invocation and
performs writes to the same map. To fix that ic.Exec() needs to
wait until all goroutines are properly exited.

```

7b632c8ee8 core: refactor natives cache 
1. Use layered natives cache. With layered cache the storeblock
process includes the following steps: create a wrapper over
current nativeCache, put changes into upper nativeCache layer,
persist (or discard) changes.
2. Split contract getters to read-only and read-and-change. Read-only
ones doesn't require the copy of an existing nativeCache item.
Read-and-change ones create a copy and after that change the copy.

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.

cd42b8b20c core: allow early Seek stop 
This simple approach allows to improve the performance of

MemoryPS's speed suffers a bit, but we don't use it for
production environment.

Part of #2322.

2c46b81864 native: optimize gas per vote calculation 
GAS per vote records are being returned from Seek in ascending way, and

iterate backwards strting from the last record using SeekBackwards.

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.

c113d682bd core: fix NEO balance state handler 
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.

64c780ad7a native: optimize totalSupply operations during token burn/mint 
We burn GAS in OnPersist for every transaction so some buffer reuse here is
quite natural.

This also doesn't change a lot in the overall TPS picture, maybe adding some
1%.

5c65d33439 native: move required balance check to token contracts 
Which duplicates the check, but deduplicates error path. This check forced
double balance deserialization which is quite costly operation, so we better
do it once.

It's hardly noticeable as of TPS metrics though, maybe some 1-2%%.

aab18c3083 stackitem: introduce Convertible interface 
We have a lot of native contract types that are converted to stack items
before serialization, then deserialized as stack items and converted back to
regular structures. stackitem.Convertible allows to remove a lot of repetitive
io.Serializable code.

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

58ab3b5ad1 core: get native nep17 balance from contract storage 
Not from DAO's items with storage.STNEP17Balances prefix, because
changes are reflected there only after notifications processing. And
this happens only after the transaction script is executed, but there
might be cases when we need to get the balance that was updated
earlier during the same transaction processing.

Affects storage dumps.
