56dcff2894 core: invoke contracts for Invocation TXes
They can have some side-effects that future invocations rely on.

74590551c4 core: add some interops
This also changes Verify to VerifyTx and VerifyWitnesses, because there is a
need to pass a block for some interop functions.

8266a5ce19 core: export GetContractState/GetScriptHashesForVerifying via Blockchainer
These are gonna be used by interops and are also useful in general.

16bc5296cb block: return error from Verify
Don't hide real problem behind the bool value. Makes it easier to identify
problems when looking at log messages.

258f397b9a core: append transactions to the block in GetBlock()
We want to get a full block, so it has to have transactions
inside. Unfortunately our tests were used to this wrong behavior and utilized
completely bogus transactions without data that couldn't be persisted, so fix
that also.

It's gonna be used in interops for key validity check.

c5a4cfaebe smartcontract: add CreateSignatureRedeemScript()
It's very similar to the CreateMultiSigRedeemScript() and it will be used in
interop functions.

238c590ddb core: fix contract state's Properties to use PropertyState
PublishTX only had one of these flags, but newer contracts (created via the
interop function) can have more and these flags are aggregated into one field
that uses PropertyState enumeration (it's used to publish contract, so
supposedly it's also a nice choice for contract state storage).

acb7ef7fbd vm: support uint8 and uint64 in makeStackItem()
Convenience to avoid casts, uint64 is also a bit special in that it can't be
converted to int64 without data loss.

6b70c5f2bd keys: rename New*FromRawBytes to New*FromASN1
RawBytes is too confusing and may be read as being compatible with
NEO-serialized format.

78861485b6 storage: simplify MemoryBatch
It's used a lot and it looks a lot like MemoryStore, it just needs not to
return errors from Put and Delete, so make it use MemoryStore internally with
adjusted interface.

13bf2618ef storage: improve PutBatch for MemoryStore
Make it look more like a real transaction, put/delete things with a single
lock. Make a copy of value in Put also, just for safety purposes, no one knows
how this value slice can be used after the Put.

3ada92944a storage: drop Len from the Batch interface
It's almost meaningless now and we can easily live without it.

e111892653 storage: redo DB testing
Make generic tests for all Store implementations, deduplicate tests. Implement
Delete() tests, test Seek() better, add LevelDB tests (finally!).

48b6a427cf storage: add Delete method for Batch and Store
It's gonna be used by Storage and Contract interops, both can delete their
data.

add9368e9d storage: use strings as keys for memory batch
Using pointers is just plain wrong here, because the batch can be updated with
newer values for the same keys.

Fixes Seek() to use HasPrefix also because this is the intended behavior.

dca332f333 vm: use new Context.Next() to properly dump programs
Fix #295, deduplicate code and add `inspect` parameter to the vm command to
dump AVMs (`contract inspect` works with Go code).

53a3b18652 vm: completely separate instruction read and execution phases
Make Context.Next() return both opcode and instruction parameter if any. This
simplifies some code and needed to deal with #295.

1bf232ad50 vm: introduce TryBool() for Element and use it in VerifyWitnesses
Script can return non-bool results that can still be converted to bool
according to the usual VM rules. Unfortunately Bool() panics if this
conversion fails which is OK for things done in vm.execute(), but certainly
not for VerifyWitnesses(), thus there is a need for TryBool() that will just
return an error in this case.

8441b31b4b vm: accept uint32 in makeStackItem()
Interop services routinely push such things (block index, blockchain height)
onto the stack.

Roman Khimov
d62a367900 vm: add Value() method to Element
It gives access to the internal value's Value() which is essential for interop
functions that need to get something from InteropItems. And it also simplifies
some already existing code along the way.

0c963875af vm: check for fault flag first in Run()
Switch cases are evaluated sequentially and the fault case is top-priority to
handle.

705c7f106f vm: don't panic if there is no result in PopResult()
This function is intended to be ran outside of the execute's panic recovery
mechanism, so it shouldn't panic if there is no result.

a357d99624 vm: introduce MaxArraySize constant
This is both for #373 and for interop functions that have to check some
inputs.

cfa0c13322 vm: add InteropItem type for interop data
This is an opaque data item that is to be used by the interop functions.

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()

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.

count doesn't equal signature count, fix it and add some comments.

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.
