* fhandler_socket.cc (fhandler_socket::evaluate_events): Slightly
	rearrange code.  Rephrase a comment.
	* fhandler_socket.cc (fhandler_socket::evaluate_events): Handle
	connect_state and af_local_connect connect call here, once, independent
	of FD_CONNECT being requested.  Add comment to explain why.
	(fhandler_socket::connect): Drop connect_state handling and calling
	af_local_connect.  Move remaining AF_LOCAL stuff prior  to calling
	::connect and explain why.  Simplify error case.
	* poll.cc (poll): Handle connect state independently of POLLOUT being
	requested for the descriptor to allow setting POLLIN if connect failed.
	Add comment.
	* select.cc (set_bits): Drop connect_state and AF_LOCAL handling here.
	* fhandler_socket.cc (fhandler_socket::af_local_connect): Drop outdated
	comment.
	(fhandler_socket::evaluate_events): Only set connect_state and call
	af_local_connect if connect_state is connect_pending.  Explain why.
	Drop redundant test for socket family and type.
	(fhandler_socket::connect): Extend comment.
	Add setsockopt(sd, SOL_SOCKET, SO_PEERCRED, NULL, 0) to disable
	initial handshake on AF_LOCAL sockets.
	* fhandler.h (class fhandler_socket): Add no_getpeereid status flag.
	(fhandler_socket::af_local_set_no_getpeereid): New prototype.
	* fhandler_socket.cc (fhandler_socket::af_local_connect): Skip handshake
	if no_getpeereid is set.  Add debug output.
	(fhandler_socket::af_local_accept): Likewise.
	(fhandler_socket::af_local_set_no_getpeereid): New function.
	(fhandler_socket::af_local_copy): Copy no_getpeereid.
	(fhandler_socket::getpeereid): Fail if no_getpeereid is set.
	* net.cc (cygwin_setsockopt): Add SO_PEERCRED for AF_LOCAL/SOCK_STREAM
	sockets.  Add comment to explain why we need it.
	* include/cygwin/version.h (CYGWIN_VERSION_API_MINOR): Bump.
