Revert code reversion from 2004-04-03. So, revert to async I/O again.

	* fhandler.h (status): Add "closed" flag.
	(prepare): New method declaration.
	(wait): Ditto.
	(release): Ditto.
	* fhandler_socket.cc: Don't include wsock_event.h.
	(fhandler_socket::prepare): New method, moved from wsock_event.
	(fhandler_socket::wait): Ditto.
	(fhandler_socket::release): New method.
	(fhandler_socket::recvfrom): Simplify loop.
	(fhandler_socket::recvmsg): Ditto.
	(fhandler_socket::sendto): Ditto.
	(fhandler_socket::sendmsg): Ditto.
	* net.cc: Don't include wsock_event.h.
	(wsock_event::prepare): Remove.
	(wsock_event::wait): Ditto.
	* wsock_event.h: Remove.
