[PATCH] setup: mirror list caching

[Igor Pechtchanski <pechtcha at cs dot nyu dot edu>]

Hi,

The attached (Q&D) patch implements rudimentary mirror list caching.  The
mirror list will be fully downloaded from sources.redhat.com every time if
possible, but if the site is down, a local copy (from last download) will
be used.  There is no true "caching" (with timestamps, etc), but this
could be refined later.

I've tested this on two WinXP machines -- seems to work.  We might want to
apply this soon and release a setup snapshot before this weekend, because
of <http://cygwin.com/ml/cygwin/2005-09/msg00993.html>.

As usual, the ChangeLog is below.

	* site.cc (get_site_list): Store mirror list locally.
	Use local copy if unable to download.

If there's any real truth it's that the entire multidimensional infinity
of the Universe is almost certainly being run by a bunch of maniacs. /DA
