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).

097ef2a731 core: copy storage item key in simple.GetStorageItems 
Related to #1468, ported from #1475.

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
until the next `f` call.

eccf639803 core: add InitializeCache method to NEO native contracts 
There might be a case when cached contract values store nil (e.g.
after restoring chain from dump). We should always initialize cached
values irrespective to the (NEO).Initialize method.

This commit fixes a bug introduced in 83e94d3
when 4-nodes privnet is failing after restoring from dump:

e4b52d3947 core/rpc: add continue flag to iterating functions 
Most of the time we don't need to get all transfers from the DB and
deserialize them.

373c669c6a core/state: reverse the order of ForEachTransfer 
When using limits we're usually concerned about the most recent
transfers. Returning 3 transfers from the middle of the chain isn't very
helpful.

ff11a5f990 state: use more efficient encoding for amount 
It's variable-length anyway, so wasting 8 bytes for what typically is 1 byte
makes no sense.

806b89db76 state: store the length of NEP5TransferLog in the first byte 
We lose `size` field after serialization/deserialization which can lead to
adding more than NEP5TransferBatchSize elements into the NEP5TransferLog.

33ea179f6e core: remove forward index check from addHeaders() 
It can't ever happen. We're guaranteed to have a consistent chain of headers
(we're verifying them above, if we're not verifying --- it's not our fault)
that starts at HeaderHeight that was actual when we were asking for it
previously. HeaderHeight can only move forward, so if that happened that would
be filtered out by the condition below and the first one can't happen. Though
to be absolutely sure change the second check to only pass "+1" headers (which
is what we want).

7cbb660082 core: rework headerList 
It's a contention point as all accesses to it are serialized and they compete
with persisting logic at the same time.

ce09c82b25 block: remove Verify() 
It's used in two places now:
 * Blockchain.AddBlock()
   This one does transaction duplication check of its own, doing it in
   Verify() is just a waste of time. Merkle tree root hash value check is
   still relevant though
 * Block.DecodeBinary()
   We're decoding blocks for the following purposes:
     - on restore from dump
       The block will be added to the chain via AddBlock() and that will do a
       full check of it (if configured to do so)
     - on retrieving the block from the DB (DAO)
       We trust the DB, if it's gone wild, this check won't really help
     - on receiving the block via P2P
       It's gonna be put into block queue and then end up in AddBlock() which
       will check it
     - on receiving the block via RPC (submitblock)
       It is to be passed into AddBlock()
     - on receiving the block via RPC in a client
       That's the only problematic case probably, but RPC client has to trust
       the server and it can check for the signature if it really
       cares. Or a separate in-client check might be added.

As we can see nothing really requires this verification to be done the way it
is now, AddBlock can just have a Merkle check and DecodeBinary can do fine
without it at all.

2e876b5593 block: remove Base.Verify() 
It's a no-op and there is nothing we can do about it, header contents could
only be checked against chain state, there is nothing to check for internal
consistency.
