Subject: sockets: connect bugfix and use poll in preference to select.

* configure: cosmetics: change HAVE_SYS_SELECT to HAVE_SELECT,
and log that the function rather than the header is being
detected.

* socket.c (fd_timeout): New function, implemented using
poll or select.
(to_connect): select logic replaced with fd_timeout. Bug
fixed: connect requires polling for writability, not
readability. If poll and select are not available,
ignore timeout argument.
(sock_accept): Use fd_timeout; fall back on non-timed-out
accept if poll or select not available.
