fcaa24f928 rpcclient: provide some exported error for disconnected WSClient
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.

Related to nspcc-dev/neofs-node#2325.

0a160ee93b *: use CompareAndSwap instead of CAS for atomics
go.uber.org/atomic deprecated CAS methods in version 1.10 (that introduced
CompareAndSwap), so we need to fix it.

dab13a4e2d rpcclient: close WSClient subscriber on overflow
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.

6eaa76520f rpcclient: close subscriber channels on wsReader exit
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.

45b353781f rpcclient: correctly handle request channel closure
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.

6b21ad9922 *: replace interface{} with any keyword
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.

6f7fed344b rpcclient: add Internal client for direct RPC server calls
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.

6dbae7edc4 rpcclient: fix WS-client unsubscription process
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.
