server/red_worker: reuse dispatcher

This patch reuses Dispatcher in RedDispatcher. It adds two helpers
to red_worker to keep RedWorker opaque to the outside. The dispatcher is
abused in three places that use the underlying socket directly:
 once sending a READY after red_init completes
 once for each channel creation, replying with the RedChannel instance
  for cursor and display.

FDO Bugzilla: 42463

rfc->v1:
* move callbacks to red_worker.c including registration (Yonit)
* rename dispatcher to red_dispatcher in red_worker.c and red_dispatcher.c
* add accessor red_dispatcher_get_dispatcher
* s/dispatcher_handle_recv/dispatcher_handle_recv_read/ and change sig to
  just Dispatcher *dispatcher (was the SpiceCoreInterface one)
* remove SpiceCoreInterface parameter from dispatcher_init (Yonit)
* main_dispatcher needed it for channel_event so it has it in
  struct MainDispatcher
* add dispatcher_get_recv_fd for red_worker
