Instead of having to manually register the file descriptor and
than need to call dispatcher_handle_recv_read just provide a single
API to create the watch.
This has some advantage:
- replace 2 API with 1;
- code reuse for handling the event (removed 2 functions);
- avoid the caller to use the file descriptor;
- avoid the caller to register wrong events.
