Previously findstorage returns null for the results key if a contract
state is not found. C# returns an empty list.

This is not the way intended in https://github.com/neo-project/proposals/pull/156.
-511 covers _both_ cases because users hardly can distinguish one from another,
it's just that our mempool implementation has error codes for both..

mempool.ErrInsufficientFunds is used when sender doesn't have enough
balance to pay the submitted transaction fees (-511 code according to
https://github.com/neo-project/proposals/pull/156). mempool.ErrConflict is
used when sender is not able to pay the overall transactions fee sum in
the pool (generic -500 error according to the proposal).
This bugfix is kind of breaking change for those users who relied on the
old -511 code previously returning "insufficient funds" error.

Added sync logs for every service separately to provide the ability to
have a custom logger for each service. This commit makes the code follow
the zap usages rules: `Sync calls the underlying Core's Sync method,
flushing any buffered log entries. Applications should take care to
call Sync before exiting.`

when block is stored (which happens after block's processing). This is

Valid transactions can't use more than MaxVerificationGAS for script execution
and this applies to the whole set of signers, so use this value by default
unless local instance configuration suggests something lower for generic
invocations.

We can ignore core.ErrInvalidSignature (which means that the script has
executed, but returned false), but we shouldn't ignore other errors which
likely mean that the script is incorrect (or hits some resource limits).
Use neorpc.ErrInvalidSignature as a return to separate this case from
contract-based verification.

`getrawnotarytransaction` takes a transaction hash and attempts to find
the corresponding transaction in the notary requests mempool. It searches
through all the verified main and fallback transactions.
`getrawnotarypool` returns hashes of all the verified transactions,
including both main and fallback transactions.
Additionally add struct result.RawNotaryPool.

Behaviour change.
`terminatesession` returns ErrUnknownSession in case of impossibility of finding session,
previously there was no-error response with `false` result.
`traverseIterator`returns ErrUnknownSession in case of impossibility of finding session,
previously there was no-error response with default result; `traverseIterator`returns ErrUnknownIterator,
there were no such errors before.
Accordingly to proposal:

Previously RPC server shutdown procedure listened to the execution
channel and stopped at the first element that arrived in the queue. This
could lead to the following problems:
* stopper could steal the execution result from subscriber
* stopper didn't wait for other subscription actions to complete
Add dedicated channel to `Server` for subscription routine. Close the
channel on `handleSubEvents` return and wait for signal in `Shutdown`.

Previously RPC server could never be shut down completely due to
some start precondition failure (in particular, inability to serve HTTP
on any configured endpoint). The problem was caused by next facts:
* start method ran subscription routine after HTTP init succeeded only
* stop method blocked waiting for the subscription routine to return
Run `handleSubEvents` routine on fresh `Start` unconditionally. With
this change, `Shutdown` method won't produce deadlock since
`handleSubEvents` closes wait channel.
