2f8e7e4d33 native: fix getvalidators to match C# implementation
ValidatorsCount is not initialized at block 0 with C# node (the first voter
initializes it) and until that initialization happens the standby validators
list is being returned as is without sorting.

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
the network fees.

9f11a55bd6 core: add policy check to mempool

so we should remove all transactions which do not meet this requirement.

Also added marshalling of nil array into `[]` instead of `null` to

8de0332107 *: use MaxTransactionsPerBlock from Policy native contract
part of #904

1. We now have MaxTransactionsPerBlock set in native Policy contract,
   so this value should be used in (dbft).GetVerified method instead
   of passing it as an argument.
2. Removed (dbft).WithTxPerBlock.
2. DBFT API has changed, so update it's version.
3. Removed MaxTransactionsPerBlock from node configuration, as we
   have it set in native Policy contract.

3729865860 compiler: reimplement for-range loops without syscalls

This approach will use 2 PICKITEMS (270_000 gas) for maps, which is
still cheaper that *.Next syscall.

7e586cc6ab native: deduce transferred assets from sender on transfer
When money is being sent usually they go away from someone's pocket, so that

bit different from usual economic's expectations.

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

Prometheus metrics are not critical to be in perfect sync and events are
asynchronous anyway.

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.
