bcc2d1bb8f dao: don't treat zero stateroot as valid during MPT init 
Because it's not really valid and MPT state should be the same as if it was
initialized at height 0. Fixes #1870

eb1986d2fc state: use big.Int for NEP5 balances and transfer amounts 
In general, NEP5 contracts are not limited to int64. And we have an example
of pnWETH Flamingo token now (with 18 decimals) that easily overflows int64,
so for correctness we need to store big.Int.

And as TransferLog is shared for different purposes I've decided to not make
it variable-length on Neo 2.

`gettransactionheight` in case transaction is in the mempool.

06f3c34981 mempool: replace timeStamp with blockStamp 
Time is not really relevant for us here and we don't use this timestamp in any
way. Yet it occupies 24 bytes and we do two clock_gettime calls to get it.

Replace it with blockStamp which is going to be used in the future for
transaction retransmissions.

It allows to improve single-node TPS by another 3%.

Close #1468.

We should copy the key to avoid bytes substitution. Otherwise there's a
chance that at the end of dao.Store.Seek(...) execution some keys won't
be the same as the original keys found inside saveToMap function.

9aee3e5a34 transaction: set output position when decoding 
We had a kludge for getrawtransaction to set this useless field, but
7e371588a7 broke it. Add it right into the
decoder now to fix all types of queries (getblock/getrawtransaction/gettxout).

Fixes #1392.

6d32751292 core: fix stateroot height update for testnet 
When synchronizing with stateroot-enabled network from genesis and if
stateroot is not enabled in block zero we were failing to update state height
because initially it's updated with a jump from 0 to StateRootEnableIndex, so
we should allow that to happen to have correct state height.

1ab4f81fc3 dao: migrate nep5 balances with the contract 
Fixes #1144. It's quite simple approach, we just update balance info right
upon contract migration. It will slow down migration transactions, but it
takes about 1-2 seconds to Seek through balances at mainnet's 3.8M, so the
approach should still work good enough. The other idea was to make lazy
updates (maintaining contract migration map), but it's more complicated to
implement (and implies that a balance get might also do a write).

There also is a concern about memory usage, it can give a spike of some tens
of megabytes, but that also is considered to be acceptable.
