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.

204d7f1c6a core: refactor runtime.CheckWitness interop 
Removed unreachable code, see
8fed383523

runtime.CheckHashedWitness can only be used for transaction
verification, the other two options from reference implementation (block
and consensus payload) have separate methods for verification.

fe1f0a7245 core: introduce CheckReturnState constants 
At the moment we should have 3 possible options to check return state
during vm context unloading:
	* no check
	* ensure the stack is empty
	* ensure the stack is not empty

It is necessary to distinguish them because new _deploy method shouldn't
left anything on stack. Example: if we use _deploy method before some
ordinary contract method which returns one value. Without these changes
the contract invocation will fail due to 2 elements on stack left after
invocation (the first `null` element is from _deploy, the second element
is return-value from the ordinary contract method).

30526046e7 native: don't push void result in Call 
This was done in https://github.com/neo-project/neo/pull/1693
for native calls. `OnPersist` script still uses `DROP` though
as value is pushed via `CheckReturn` logic for regular calls.

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.

0e2784cd2c always wrap errors when creating new ones with fmt.Errorf()

5ef08f60ae remove github.com/pkg/errors from dependencies 
It's not needed any more with Go 1.13 as we have wrapping/unwrapping in base
packages. All errors.Wrap calls are replaced with fmt.Errorf, some strings are
improved along the way.

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.
