21efccd300 transaction: remove type field, set Version to 0 
Two changes being done here, because they require a lot of updates to
tests. Now we're back into version 0 and we only have one type of
transaction.

It also removes GetType and GetScript interops, both are obsolete in Neo 3.

7633439845 rpc/block: rework the way Block is JSONized 
Our block.Block was JSONized in a bit different fashion than result.Block in
its NextConsensus and Index fields. It's not good for notifications because
third-party clients would probably expect to see the same format. Also, using
completely different Block representation is probably making our client a bit
weaker as this representation is harder to use with other neo-go components.

So use the same approach we took for Transactions and wrap block.Block which is
to be serialized in proper way.

Fix `Script` JSONization along the way, 3.0 node wraps it within `witnesses`.

bef14977a2 rpc/client: add notifications support for WSClient 
It differs from #895 design in that we have Notifications channel always
exposed as WSClient field, probably it simplifies things a little.

Roman Khimov
fc22a46a4c rpc/server: add notification subscription 
Note that the protocol differs a bit from #895 in its notifications format,
to avoid additional server-side processing we're omitting some metadata like:
 * block size and confirmations
 * transaction fees, confirmations, block hash and timestamp
 * application execution doesn't have ScriptHash populated

Some block fields may also differ in encoding compared to `getblock` results
(like nonce field).

I think these differences are unnoticieable for most use cases, so we can
leave them as is, but it can be changed in the future.

612500ed96 rpc/server: start and shutdown Server in tests 
It will be important for proper subscription testing and it doesn't hurt even
though technically we've got two http servers listening after this change (one
is a regular Server's http.Server and one is httptest's Server). Reusing
rpc.Server would be nice, but it requires some changes to Start sequence to
start Listener with net.Listen and then communicate back its resulting
Addr. It's not very convenient especially given that no other code needs it,
so doing these changes just for a bit cleaner testing seems like and
overkill.

Update config appropriately. Update Start comment along the way.

0cb6dc47e4 vm: implement slot-related opcodes 
1. Slot is a new mechanism for storing variables during execution
which is more convenient than alt.stack. This commit implements
support for slot opcodes in both vm and compiler.
2. Remove old alt.stack opcodes.
3. Do not process globals at the start of every function, but instead
load them single time at main.

7287c01bd0 rpc/server: rework submitblock empty test 
The original intention here was to check for server reaction in presence of
validation errors (response.ErrValidationFailed) and it was very easy to make
validation fail for block without transactions in Neo 2. But in Neo 3
transactionless blocks are perfectly valid (see
29d321b5e1) which broke this test even though we
didn't see it until websocket addition (which required
8cec6694ae to make this test work initially).

So make a valid block and then spoil its verification script.

It reduces heap pressure a little for these elements as we don't have to

de2eeb4671 rpc: add one to the block height for the getblockcount response 
There is a difference in interpretation of what a block count is. neo-go nodes
currently respond to this request with the latest block number which is the
same number that neoscan.io shows. However, C# nodes deliberately do add one
to this number when answering to the getblockcount request to account for the
genesis block number 0.

This patch makes us consistent with C# nodes wrt to getblockcount behaviour.

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).

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.
