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 returns a fallback or main transaction that was
previously added to the memory pool by P2PNotaryRequest. This function
invokes the RPC server's `getrawnotarytransaction` method.
GetRawNotaryPool returns hashes from all the verified transactions,
including both main and fallback transactions. This function invokes
the RPC server's `getrawnotarypool` method.
Also, these functions were added to doc.go.

`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.

Do not retrieve the whole set of storage items when trying to find
the ones from the specified start. Use DAO's Seek interface
implemented over MPT TrieStore to retrieve only the necessary items.

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:

Also adding description of `traverseIterator` in docs/rpc.md.

This change makes code incompatible with C# node,
because currently no error is returned on invalid proof.
According to proposal:

And simplify atomic service value stored by RPC server. Oracle service can
either be an untyped nil or be the proper non-nil *oracle.Oracle.
Otherwise `submitoracleresponse` RPC handler doesn't work properly.

Ensure that Scopes can be properly parsed not only from the string
representation, but also from a single byte. transaction.Signer
is not affected (checked against the C# implementation), only
RPC-related signer scopes are allowed to be unmarshalled from byte.

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.

There is an existing problem with RPC server shutdown freeze after start
failure due to some init actions (at least HTTP listen) described in
#2896.
Add dedicated unit test which checks that `Shutdown` returns within 5s
after `Start` method encounters internal problems.

Everywhere including examples, external interop APIs, bindings generators
code and in other valuable places. A couple of `interface{}` usages are
intentionally left in the CHANGELOG.md, documentation and tests.
It has a special `requestF` and a special initialization function, but other
than that it's an absolutely regular WSClient. Can be used to call, can be
used to subscribe. Fixes#2909.
According to docs, `Server` uses provided error channel only to write
encountered error to it. In this case, there is no need to accept rw
channel to create `Server` instance. Strengthening the type to
write-only will allow the caller to ensure control of reading errors
from the provided channel.
The change is backward compatible since any `chan` is `chan<-`.
