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.

ce402a70d2 core: add policy check to (*Blockchain).verifyTx method

Policy blocked accounts list, transaction is invalid.

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.

05dad10e82 native: fix native contract onPersist script

Don't change our implementation in `emit`, because PACK is cheaper and
this script must not depend on the internal details of `emit` package anyway.

b483c38593 block/transaction: add network magic into the hash 
We make it explicit in the appropriate Block/Transaction structures, not via a
singleton as C# node does. I think this approach has a bit more potential and
allows better packages reuse for different purposes.
