8537700b7b core: sort hashes and witnesses in VerifyWitnesses() 
Fixes failure to verify some multi-witnesses transactions in Testnet chain. C#
code contains similar logic.

dd0dd2d031 core: add claim-specific GetScriptHashesForVerifying() 
Claim transactions have different logic in C# node, so we need to
implement it too. It's not the most elegant way to fix it, but let's make it
work first and then refactor if and where needed. Fixes verification of Claim
transactions.

Merge pull request #414 from nspcc-dev/persistence-rewamp 
What started as an attempt to fix #366 ended up being quite substantial refactoring of the Blockchain->Store and Server->Blockchain interactions. As usually, some additional problems were noted and fixed along the way. It also accidentally fixes #410.

af557cea19 storage: deduplicate BoltDBBatch/MemoryBatch 
BoltDB doesn't have internal batching mechanism, thus we have a substitute for
it, but this substitute is absolutely identical to MemoryBatch, so it's better
to unify them and import ac5d2f94d3 fix into the
MemoryBatch.

920d7c610c core: remove blockCache, use MemoryStore, redesign persist() 
Commit 578ac414d4 was wrong in that it saved
only a part of the block, so depending on how you use blockchain, you may
still see that the block was not really processed properly. To really fix it
this commit introduces intermediate storage layer in form of memStore, which
actually is a MemoryStore that supports full Store API (thus easily fitting
into the existing code) and one extension that allows it to flush its data to
some other Store.

It also changes AddBlock() semantics in that it only accepts now successive
blocks, but when it does it guarantees that they're properly added into the
Blockchain and can be referred to in any way. Pending block queing is now
moved into the server (see 8c0c055ac657813fe3ed10257bce199e9527d5ed).

So the only thing done with persist() now is just a move from memStore to
Store which probably should've always been the case (notice also that
previously headers and some other metadata was written into the Store
bypassing caching/batching mechanism thus leading to some inefficiency).

c531dc0bde network: add block queue 
This one will replace blockCache in Blockchain itself as it can and should be
external from it. The idea is that we only feed successive blocks into the
Blockchain and it only stores valid proper Blockchain and nothing else.

578ac414d4 core: make unpersisted blocks/txs available in Blockchain 
This changes the Blockchain to also return unpersisted (theoretically, verified
in the AddBlock!) blocks and transactions, making Add/Get interfaces
symmetrical. It allows to turn Persist into internal method again and makes it
possible to enable transaction check in GetBlock(), thus fixing #366.

ac5d2f94d3 storage: fix BoltDB batched Put() 
It must copy both the value and the key because they can be reused for other
purposes between Put() and PutBatch(). This actually happens with values in

100fee164b unitTest: reworked RPC unit test 
earlier we had an issue with failing test in #353 and other one #305.
Reworked these test to have in-memory database. This led to multiple
changes: made some functions like Hash and Persist public(otherwise
it's not possible to control state of the blockchain); removed
unit_tests storage package which was used mainly for leveldb in unit
tests.
I see these tests not really good since they look like e2e tests and
as for me should be run in separate step against dockerized env or
in case we want to check rpc handler we might want to rework it in order
to have interface for proper unit tests.
As for me this patchset at least makes as safe with not removing totally
previous tests and at the same time CircleCI will be happy now.

4395cea344 storage: fix reading overlapping hash blocks from the DB 
In the unlikely event of overlapping hash block written to the DB we might end
up with wrong hash list. That happened to me for some reason when synching
with the testnet leading to the following keys with respective values:
  150000 -> 2000 hashes
  152000 -> 2000 hashes
  153999 -> 2000 hashes

Reading it hashes number 153999 and 154000 got the same values and the chain
couldn't sync correctly.

7812fb28ea core: optimize blockchain init with existing DB 
There is no need to generate genesis block (it's already in the DB) and we can
add all hashes at once without iterating over them.

fc1075bf75 vm: protect PUSHDATA from short reads 
Same thing done in a2a8981979 for PUSHBYTES,
failing to read the amount of bytes specified should lead to FAULT. Also
makes readUint16() and readUint32() panic as this is the behavior we want in
these cases. Add some tests along the way.

5bd666b786 vm: return NOP as current instruction for just loaded VM 
Before:
NEO-GO-VM > loadgo h.go
READY: loaded 16 instructions
NEO-GO-VM > ip
instruction pointer at -1 (PUSH0)

After:
NEO-GO-VM > loadgo h.go
READY: loaded 16 instructions
NEO-GO-VM > ip
instruction pointer at -1 (NOP)

I think NOP is a little less scary.

7b0c2781d2 vm: expand instruction list with commands from current VM spec 
Current NEO documentation lists them:
https://docs.neo.org/docs/en-us/tooldev/advanced/neo_vm.html

CALL_* instructions were left out because of conflict with golint (but they're
removed in NEO 3.0 anyway, so wasting time on them makes no sense).

Update autogenerated instruction_string.go accordingly.
