8fed383523 core: adjust System.Runtime.CheckWitness interop 
Part of #1055.

It should have `AllowStates` flag.

Also removed unreachable code: we can't have such situation when
script container is not a transaction in the scope of `CheckWitness`
method because:
1. Blocks have their own implementation of CheckWitness for
internal usage (it's (bc *Blockchain) verifyHeaderWitnesses method).
2. For the outside calls of System.Runtime.CheckWitness interop (e.g.
calls from smart-contract) script container is always a transaction.

ae9658a108 dao: migrate nep5 balances with the contract 
Fixes #1144. It's quite simple approach, we just update balance info right
upon contract migration. It will slow down migration transactions, but it
takes about 1-2 seconds to Seek through balances at mainnet's 3.8M, so the
approach should still work good enough. The other idea was to make lazy
updates (maintaining contract migration map), but it's more complicated to
implement (and implies that a balance get might also do a write).

There also is a concern about memory usage, it can give a spike of some tens
of megabytes, but that also is considered to be acceptable.

842feb2533 core: adjust System.Contract.Update interop 
Part of #1055.

We should check contract scripthash against the one provided in manifest
and manifest groups. We shouldn't put on stack anything after return.
And ofcourse, we mast not destroy the old contract at the end, as
`contractDestroy` removes all storage items associated with the
old contract ID (which equals to the new contract ID). We just remove
old contract state - it's enough.

a1f98f92fe compiler: add ConvertResultToStruct flag 
Part of #1055.

There'll be a lot of interops which result with a struct on stack instead
of interop interface, and sometimes their names are the same, so it's
unrelyable to take into account interop name only and don't pay
attention to it's API (package).

Also sort syscalls by package and name.

a46c71f2de consensus: prevent synchronization stalls 
When CN is not up to date with the network is synchonizes blocks first and
only then starts consensus process. But while synchronizing it receives
consensus payloads and tries to process them even though messages reader
routine is not started yet. This leads to lots of goroutines waiting to send
their messages:

Luckily it doesn't break synchronization completely as eventually connection
timers fire, the node breaks all connections, create new ones and these new
ones request blocks successfully until another consensus payload stalls them
too. In the end the node reaches synchronization, message processing loop
starts and releases all of these waiting goroutines, but it's better for us to
avoid this happening at all.

This also makes double-starting a no-op which is a nice property.

is http.ErrServerClosed. This should also fix the following test failure:

Fixes state mismatch for the key ffffffff0e00000000000000000000000000000001 in
the first blocks.

It also affects tests as now the first validator is different and it receives

Closes #913.
Provide package info in the funcScope to check if function is defined
insided an interop package. As a good side-effect bytecode for builtins from `util`
is no longer emitted.

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`.

44ae9086b6 core: improve and fix 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.

Native contracts also don't require any locks and they should be processed
before dumping storage changes.

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.

Get new blocks directly from the Blockchain. It may lead to some duplications

network server like RPC (submitblock call). And it simplifies network server
at the same time.

c7a040ff81 core: fix bug with native contracts methods initialisation 
`NewNEO()` and `NewGAS()` methods are trying to initialise
both `onPersist` and `incBalance` methods of NEO and GAS AFTER
nep5TokenNative is set to the VALUE of created nep5 token.
In this situation an attemmpt to call the corresponding native contracts
methods (e.g. transfer native GAS) leads to contract invocation failure,
as far as `nep5TokenNative.incBalance` method is nil.

Fixed this by initializing both `onPersist` and `incBalance` methods
before getting the value of nep5 contract.

4ebac5a069 core: fix bug in nep5 notifications handling 
Native contracts deployment creates `Transfer` notifications and adds
them into interop context. However, these notifications were not stored
for two reasons:
1. typo in `Transfer` (so these notifications were not recognised during
processing of the invocation tx in (*Blockchain).storeBlock(...) method)
2. these notifications have `from` adress setted to null, so conversion
to []byte fails. Same thing could happen with `to`.

Related C# issue: https://github.com/neo-project/neo/issues/1646

For now, made both `transfer` and `Transfer` valid.

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.

315aabde56 client: make http.Client internal to the Client 
Exposing it the outside users is strange, so incapsulate it completely.

Fix DialTimeout setting along the way, handle negative timeouts as invalid.
