d93aa745bb contract: avoid going to the DB for entry scripts 
This optimizes out DB access for non-deployed contracts under the assumption
that deployed ones are always loaded via `LoadScriptWithHash` (and if they're
not --- it's a bug anyway with the new hashing model) which actually is a very
popular case (every entry script does that).

2fee69f26f core: add missing onPersist and postPersist methods to natives 
Although not every contract is persisted (see
https://github.com/neo-project/neo/blob/master/src/neo/Ledger/Blockchain.cs#L94)
we have to add `onPersist` and `postPersist` methods to every
native contract in order to display them in manifest for users and
follow C# behaviour. In C# there are `onPersist` and `postPersist`
methods in base native contract class, see
https://github.com/neo-project/neo/blob/master/src/neo/SmartContract/Native/NativeContract.cs#L141

54e6bcad12 core: fix failing mempool test 
There might be a case when identical nonces are generated for tx6, tx7 or
tx8 (they are not in mempool, so each of them pass mempool-presence
check). In this case test fails due to the lack of hashes into mp.conflicts
map (two of tx6, tx7 or tx8 have identical hashes) with the following
error:

```
=== RUN   TestMempoolAddRemoveConflicts
--- FAIL: TestMempoolAddRemoveConflicts (0.00s)
    mem_pool_test.go:376:
        	Error Trace:	mem_pool_test.go:376
        	Error:      	Not equal:

        	            	actual  : 3
        	Test:       	TestMempoolAddRemoveConflicts

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.

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).

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 because
storage.Seek can guarantee that provided key and value are only valid
