806b89db76 state: store the length of NEP5TransferLog in the first byte 
We lose `size` field after serialization/deserialization which can lead to
adding more than NEP5TransferBatchSize elements into the NEP5TransferLog.

53c014a0bb crypto/consensus: sign hashes and cache them for consensus payloads 
Avoid serializing payload again and again for various purposes. To sign it, we
only need a hash.

Some 2.4% gain in TPS could be achieved with this.

43b28ffa06 core: get rid of NEP5TransferSize 
Part of #1133

It will help us to use big.Int to store amount of NEP5 tokens. As far as
big.Int doesn't have constant size, we shouldn't use `NEP5TransferSize`
constant anymore.

32401a567e core: store NEP5Transfers in batches 
This is an append-only log which is read only during some RPCs.
It is rather slow to get it from base every time we need to append to
it. This commit stores all NEP5Transfers in batches, so that
only a last batch needs to be unmarshaled during block processing.

23464401bc core/state: merge spent and unspent coins state, use it to store more things 
This change reduces pressure on DB by doing the following things:
 * not storing additional KV pair for SpentCoin
 * storing Output right in the UnspentCoin, thus eliminating the need to get a
   full transaction from DB

At the same time it makes UnspentCoin more fat and hot, but it should probably
worth it.

Also drop `GetUnspentCoinStateOrNew` as it shouldn't ever existed, UTXOs
can't come out of nowhere.

1.5M block import time (VerifyBlocks disabled) on AMD Ryzen 5 1600/16GB/HDD,
before:
real    302m9.895s
user    96m17.200s
sys     13m37.084s

after:
real    159m16.551s
user    69m58.279s
sys     7m34.334s

So it's almost two-fold which is a great improvement.

c8a248596e core: introduce ValidatorsCount, make a proper count 
We were completely lacking ValidatorsCount that is supposed to track the
number of votes with particular count of consensus nodes which in theory can
change the number of active consensus nodes (if it ever to exceed the number
of standby validators), so we were not producing the right count and based on
that not giving the right set of validators.

Fixes #512.

807309a0de core/state: only drop unregistered non-voted validators 
Simple as that: UnregisteredAndHasNoVotes != !RegisteredAndHasVotes

Registered validators should stay in the DB, we might be in the process of
updating votes for them and that starts with subtraction.

6896b40dee state: use open-coded array (de)serialization for accounts 
We're spending a lot of time here, 100K blocks import starting at 1.4M, before
this patch:
real    4m17,748s
user    6m23,316s
sys     0m37,866s

After:
real    3m54,968s
user    5m56,547s
sys     0m39,398s

9% is quite a substantial improvement to justify this change.

54d888ba70 io: add type-specific read/write methods 
This seriously improves the serialization/deserialization performance for
several reasons:
 * no time spent in `binary` reflection
 * no memory allocations being made on every read/write
 * uses fast ReadBytes everywhere it's appropriate

It also makes Fixed8 Serializable just for convenience.
