Log message:
	* Merge HEAD into cv-branch.
	
	* fhandler.h (class fhandler_socket): Add wsock_mtx, wsock_evt
	and wsock_events members.  Remove closed status flag, add listener
	status flag.  Accomodate new implementation of socket event handling
	methods.  Declare recv* and send* functions ssize_t as the POSIX
	equivalents.
	(fhandler_socket::recv_internal): Declare.
	(fhandler_socket::send_internal): Ditto.
	* fhandler_socket.cc (EVENT_MASK): Define mask of selected events.
	(fhandler_socket::fhandler_socket): Initialize new members.
	(fhandler_socket::af_local_setblocking): Don't actually set the
	socket to blocking mode.  Keep sane event selection.
	(fhandler_socket::af_local_unsetblocking): Don't actually set the
	socket to previous blocking setting, just remember it.
	(struct wsa_event): New structure to keep event data per shared
	socket.
	(NUM_SOCKS): Define number of shared sockets concurrently handled by
	all active Cygwin processes.
	(wsa_events): New shared datastructure keeping all wsa_event records.
	(socket_serial_number): New shared variable to identify shared sockets.
	(wsa_slot_mtx): Global mutex to serialize wsa_events access.
	(search_wsa_event_slot): New static function to select a new wsa_event
	slot for a new socket.
	(fhandler_socket::prepare): Rewrite.  Prepare event selection
	per new socket.
	(fhandler_socket::wait): Rewrite.  Wait for socket events in thread
	safe and multiple process safe.
	(fhandler_socket::release): Rewrite.  Close per-socket descriptor
	mutex handle and event handle.
	(fhandler_socket::dup): Duplicate wsock_mtx and wsock_evt.  Fix
	copy-paste error in debug output.
	(fhandler_socket::connect): Accomodate new event handling.
	(fhandler_socket::listen): Set listener flag on successful listen.
	(fhandler_socket::accept): Accomodate new event handling.
	(fhandler_socket::recv_internal): New inline method centralizing
	common recv code.
	(fhandler_socket::recvfrom): Call recv_internal now.
	(fhandler_socket::recvmsg): Ditto.  Streamline copying from iovec
	to WSABUF.
	(fhandler_socket::send_internal): New inline method centralizing
	common send code.
	(fhandler_socket::sendto): Call send_internal now.
	(fhandler_socket::sendmsg): Ditto.  Streamline copying from iovec
	to WSABUF.
	(fhandler_socket::close): Call release now.
	(fhandler_socket::ioctl): Never actually switch to blocking mode.
	Just keep track of the setting.
	* net.cc (fdsock): Call prepare now.
	(cygwin_connect): Revert again to event driven technique.
	(cygwin_accept): Ditto.
	* poll.cc (poll): Don't call recvfrom on a listening socket.
	Remove special case for failing recvfrom.
	* include/sys/socket.h: Declare recv* and send* functions ssize_t as
	requested by POSIX.
