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.
