The vhost FD manager provides a way for the read/write callbacks to request removal of their associated FD from the epoll FD set. Problem is that it is missing a cleanup callback, so the read/write callback requesting the removal have to perform cleanups before the FD is removed from the FD set. It includes closing the FD before it is removed from the epoll FD set.
This series introduces a new cleanup callback which, if implemented, is closed right after the FD is removed from FD set.
