There are use-cases when not only Actor, but also Invoker and even
simple RPC client must wait (e.g. sendtx or dumptx CLI commands). Actor
requires optional signers in constructor, and it's not always
appropriate to create Actor only to be able to use Waiter, sometimes
it's needed to use only Waiter without Actor.

New event is to notify the user about header's content by the moment
when block is stored (which happens after block's processing). This is
needed for proper Waiter work.

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.

The reader is about to exit and it will close legacy c.Notifications, but it
will leave subscription channels at the same time. This is wrong since these
channels will no longer receive any new events, game over.

wsReader() closes c.done first and then goes over the list of
c.respChannels. Technically this means that any of the two can be taken in

Regular Client doesn't care much about connections, because HTTP client's Do
method can reuse old ones or create additional ones on the fly. So one request
can fail and the next one easily succeed. WSClient is different, it works via
a single connection and if it breaks, it breaks forever for this
client. Callers will get some error on every request afterwards and it'd be
nice for this error to be the same so that API users could detect
disconnection this way too.

Close#2894.
It should be noted that the subscriber's channel is being removed from the
list of receivers and closed, but it is still *in the list of subscribers*
and no unsubscription is performed by WSClient. Which means that RPC server
keeps sending notifications to WSClient and WSClient keeps dropping them
(because there's no receiver for this subscription and it's OK, WSClient
can handle this and this behaviour is documented). However, it's still the
caller's duty to call Unsubscribe() method for this subscription.

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.
`Actor.MakeUnsignedUncheckedRun` method imposes restriction to
`CalculateNetworkFee` method's implementations: `Hash` or `Size` methods
must not be called on the pointer to the given transaction.
Add docs to adjust described requirement.

Let upper-layer APIs like actor.Send() return it as well. Server can return
"already exists" which is an error and yet at the same time a very special
one, in many cases it means we can proceed with waiting for the TX to settle.
If VUB-th block is received, we still can't guaranty that transaction
wasn't accepted to chain. Back this situation by rolling back to a
poll-based waiter.
Do not block subscribers until the unsubscription request to RPC server
is completed. Otherwise, another notification may be received from the
RPC server which will block the unsubscription process.
At the same time, fix event-based waiter. We must not block the receiver
channel during unsubscription because there's a chance that subsequent
event will be sent by the server. We need to read this event in order not
to block the WSClient's readloop.
Execution events are followed by block events, not vise versa, thus,
we can wait until VUB block to be accepted to be sure that
transaction wasn't accepted to chain.
