Re: pg_hba.conf: samehost and samenet

Attached is a new patch, which I hope addresses all the concerns raised.

Removed configure and pg_config.h.in from the patch.

getifaddr() is at least supported on *BSD, Linux and AIX.

In the new patch, I've added support for other unixes like Solaris,
HPUX, IRIC, SCO Unix (using the SIOCGIFCONF ioctl). Also included is
Win32 support (using winsock's SIO_GET_INTERFACE_LIST).

Obviously I don't have all of the above proprietary unixes to test on,
but I've studied documentation, and I believe that the code in the patch
will run on those systems.

Done.

I need some sort of a login to add a patch to the commit fest. Is that
something I can get? Or is there someone I should ask to add my patch to
the commit fest? I hope I'm not being dense and missing something
obvious. :)
