winbind: Handle child requests in a tevent_fd
This enables the use of standard tevent_loop_once in the child, which
now also uses epoll where available.

winbind: Introduce "struct child_handler_state"
This will make the next patch simpler. child_handler_state contains the
information that the handler for the parent fde needs to pass to
process_child_request
