9d6b0ee4a8 compiler: disallow comparing slices with nil
NEO VM does not distinguish between empty and nil slices. Supporting
this is not easy and requires changing lots of other opcodes.
Pointers are not supported anyway and slices can be checked for
emptiness by inspecting their `len`.

bf6aa02dcf compiler: set default values for complex struct fields
Set default value also for complex (struct, map) types.
Note: because VM does not distinguish empty array and nil array,
comparison 'a == nil' can't be handled properly without substantial
effort. This will be fixed in NEO3.

a1c4d7ce26 core: do MPT compaction every once in a while
We need to compact our in-memory MPT from time to time, otherwise it quickly
fills up all available memory. This raises two obvious quesions --- when to do
that and to what level do that.

As for 'when', I think it's quite easy to use our regular persistence interval
as an anchor (and it also frees up some memory), but we can't do that in the
persistence routine itself because of synchronization issues (adding some
synchronization primitives would add some cost that I'd also like to avoid),
so do it indirectly by comparing persisted and current height in `storeBlock`.

Choosing proper level is another problem, but if we're to roughly estimate one
full branch node to use 1K of memory (usually it's way less than that) then we
can easily store 1K of these nodes and that gives us a depth of 10 for our
trie.

e3af560d11 dao: optimize storage cache flushing
Items were serialized several times if there were several successful
transactions in a block, prevent that by using State field as a bitfield (as
it almost was intended to) and adding one more bit. It also eliminates useless
duplicate MPT traversions.

Confirmed to not break storage changes up to 3.3M on testnet.

6c06bc57cc core: implement key recover interops
Implement secp256k1 and secp256r1 recover interops, closes #1003.

Note:

We have to implement Koblitz-related math to recover keys properly
with Neo.Cryptography.Secp256k1Recover interop as far as standard
go elliptic package supports short-form Weierstrass curve with a=-3
only (see https://github.com/golang/go/issues/26776 for details).
However, it's not the best choise to have a lot of such math in our
project, so it would be better to use ready-made solution for
Koblitz-related cryptography.

103c45850a mpt: implement (*Trie).Collapse()
Because trie size is rather big, it can't be stored in memory.
Thus some form of caching should also be implemented. To avoid
marshaling/unmarshaling of items which are close to root and are used
very frequenly we can save them across the persists.
This commit implements pruning items at the specified depth,
replacing them by hash nodes.

9546e021a9 rpc/block: rework the way Block is JSONized
Our block.Block was JSONized in a bit different fashion than result.Block in
its Nonce and NextConsensus 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 in result 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.Base which is
to be serialized in proper way.

78716c5335 rpc/client: add support for notification filters
Differing a bit from #895 draft specification, we won't add `verifier` (or
signer) for Neo 2, it's not worth doing so at the moment.

966ff28091 rpc: add subscriber queue overflow check
It's not practical adding server-side tests for 2.0 (as it requires generating
more blocks), so we'll leave it for 3.0.

9454ef5c28 core: improve locking in storeBlock
Getting batch, updating Prometheus metrics and pushing events doesn't require
any locking: batch is a local cache batch that no one outside cares about,
Prometheus metrics are not critical to be in perfect sync and events are
asynchronous anyway.

5464f9c3ae 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.

e1408b6525 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.

29ada4ca46 smartcontract: add JSON marshal/unmarshal for InteropType
We actually have to do that in order to answer getapplicationlog requests for
transactions that leave some interop items on the stack. It follows the same
logic our binary serializer/deserializes does leaving the type and stripping
the value (whatever that is).

d5df1212c2 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.

dd8bcfae47 consensus: remove OnNewBlock(), use Blockchain subscription
Get new blocks directly from the Blockchain. It may lead to some duplications
(as we'll also receive our own blocks), but at the same time it's more
correct, because technically we can also get blocks via other means besides
network server like RPC (submitblock call). And it simplifies network server
at the same time.

99d0bafa2c compiler: add ability to generate .abi.json file
A part of integration with NEO Blockchain Toolkit (see #902). To be
able to deploy smart-contract compiled with neo-go compiler via NEO
Express, we have to generate additional .abi.json file. This file
contains the following information:
 - hash of the compiled contract
 - smart-contract metadata (title, description, version, author,
email, has-storage, has-dynamic-invoke, is-payable)
 - smart-contract entry point
 - functions
 - events

However, this .abi.json file is slightly different from the one,
described in manifest.go, so we have to add auxilaury stractures for
json marshalling. The .abi.json format used by NEO-Express is described
[here](https://github.com/neo-project/neo-devpack-dotnet/blob/master/src/Neo.Compiler.MSIL/FuncExport.cs#L66).
