This one doesn't really work now, it's Legacy. Replace with something N3-ish.

Try to subscribe for headers firstly, and then if RPC server doesn't
have this ability, fallback to block subscriptions to manage transaction
awaiting.

Adjust names of all used structures, no need to duplicate `Waiter` everywhere,
we already in the `waiter` package. Also, adjust comments to Actor so that links
to Waiter are properly described in docs.

It can be used to work with the results of
CreateCallAndPrefetchIteratorScript() execution. The first item must be
an array and the optional second item must be an iterator, containing
remaining elements.

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.

This was recently added in neotest, but working with the real RPC is
still not enjoyable. This commit extends `wallet.Account` with
invocation script builder to aid network fee calculations and signing.

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
this select.

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.
