e4bf531e3e core: implement System.Binary.Atoi/Itoa syscalls 
They follow C# conversion rules, but differ from our `bigint` module
conversions:
1. String must be big-endian.
2. Sign extension is 4-bit in size (single hex character)
   and not 8-byte.

8fed383523 core: adjust System.Runtime.CheckWitness interop 
Part of #1055.

It should have `AllowStates` flag.

Also removed unreachable code: we can't have such situation when
script container is not a transaction in the scope of `CheckWitness`
method because:
1. Blocks have their own implementation of CheckWitness for
internal usage (it's (bc *Blockchain) verifyHeaderWitnesses method).
2. For the outside calls of System.Runtime.CheckWitness interop (e.g.
calls from smart-contract) script container is always a transaction.

d4c3a17883 interop/native: always use proper ScriptHashGetter, fix #924 
All scripts are run in VM, so it's there to tell us about script hashes
involved and it must be used instead of nep5ScriptHash kludge.
