b5185d5d1a core: refactor System.Storage.Get[ReadOnly]Context interops 
Part of #1055.

Split methods, as they have a lot of common code. This also fixex nil
error of storageGetReadOnlyContext in case when contract does not have
storage.

ae9658a108 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.

842feb2533 core: adjust System.Contract.Update interop 
Part of #1055.

We should check contract scripthash against the one provided in manifest
and manifest groups. We shouldn't put on stack anything after return.
And ofcourse, we mast not destroy the old contract at the end, as
`contractDestroy` removes all storage items associated with the
old contract ID (which equals to the new contract ID). We just remove
old contract state - it's enough.

fddad0b475 core: adjust System.Contract.Create interop 
Part of #1055.

contract state as a struct (not interop interface).

d4c3a17883 interop/native: always use proper ScriptHashGetter, fix #924

involved and it must be used instead of nep5ScriptHash kludge.

We were accepting transactions with zero system fee, but we shouldn't do
that. Also, transaction's verification execution has to be limited by network

7eef895061 consensus: use GetNextBlockValidators where appropriate 
GetValidators without parameter is called upon DBFT initialization and it
should receive validators for the next block (that will create it),
parameterized GetValidators is used for NextConsensus calculation where we

big.Int doesn't have constant size, we shouldn't use `NEP5TransferSize`
constant anymore.
