37d44b94e1 native: fix netfee gas redistribution 
Preview2 testnet:
file BlockStorage_100000/dump-block-12000.json: block 11562: key mismatch: feffffff1454a6cb279fbcedc66162ad4ad5d1d910202b92743e000000000000000000000005 vs feffffff1431b7e7aea5131f74721e002c6a56b610885813f79e000000000000000000000005

Originally this code was written to run after transactions processing, but
after 0fa4c49735 it works in different manner.

e5f05790d5 core: cache standby validators in the Blockchain

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 
After block was stored it's possible to have new FeePerByte constraint,
so we should remove all transactions which do not meet this requirement.
Also caching of FeePerByte was added in order not to re-verify
transactions each time mempool needs to be updated.

9097a1a23d smartcontract: update (Parameter).MarshalJSON method 
MarshalJSON should be defined on structure (not pointer), as we use
structures to marshal parameters (e.g. in NotificationEvent and
Invoke of RPC result package) and never use pointers for that purpose.

Also added marshalling of nil array into `[]` instead of `null` to
follow C# implementation.

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 
System.Enumerator.Next costs 1_000_000 gas which is rather big for a
single iteration. Reimplement this by saving current counters on stack.
This approach will use 2 PICKITEMS (270_000 gas) for maps, which is
still cheaper that *.Next syscall.

e32d0e01af compiler|transaction: remove transaction.GetUnspentCoins support 
It's useless. Even though there is Neo.Transaction.GetUnspentCoins syscall
that can be used, its return type is an interop structure that's not accepted
by any other syscall, so you can't really do anything with it. And there is no
such interface for the .net Framework.

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.

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.
