c567307748 core: fix potential issue with header list init
If we're to receive some 500 headers (less than `headerBatchCount`) and quit
before receiving more of them we end up with clean `bc.headerList` that will
be inited going backwards to the `targetHash`, but code path doesn't add add
the `targetHash` itself which it should do in this particular case, otherwise
we end with no genesis block hash in the list.

07c2105aa5 core: log values from the store in persist()
We're about stored values here, so print those, which avoids blocking in
bc.HeaderHeight() and removes duplication between blockHeight and
persistedHeight. Fixes saving the blockchain on exit (deferred function in
Run() blocked in persist()).

Test modification was required because storeBlocks() doesn't actually save
headers and thus TestGetTransaction started to fail on persist().

gonna be written into the DB and init() would panic because
bc.headerList.Len() would return 0. Use genesis block as a target in this

Script can return non-bool results that can still be converted to bool

not for VerifyWitnesses(), thus there is a need for TryBool() that will just

b7c1efe7e3 core: fix References() result key type
If the block references two ouputs in some other transaction the code failed
to verify it because of key collision. C# code implements it properly by using
full CoinReference type as a key, so let's do it in a similar fashion.

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.

832c56f97d core: fix DutyFlag check in GetScriptHashesForVerifying()
It's a flag (used by Share and Invoice asset types), so it should be checked
like a flag, the same way C# node does.

4ae18e8ffc block: check for Transaction length before messing with txes
Fixes panic two lines below. Blocks without transactions are invalid by
definition, so there is a need to adjust tests accordingly.

7779ad6c28 storage: always return ErrKeyNotFound when key is not found
It was true for MemoryStore and BoltDB, but not for LevelDB and Redis.

3c40a53c4d core: no need to Close() Blockchain in tests
It's a Store method actually and for every Blockchain that uses Run() the
Close() will be handled automatically on exit because of context magic.

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.

4a732d97ac storage: add comments about errors from MemoryStore
It never returns errors for some operations and this knowledge can be used by
other code.

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.
