"upset2"

[Christopher Faylor]

I've moved 'upset' to a new home and have begun modularizing the upset
perl code so that it will be possible to write a setup.hint 'linter'.

The new home for upset is

cvs -d :pserver:anoncvs@sources.redhat.com:/cvs/sourceware co infra/bin/cygwin

upset2 also lives there.  It is a work in progress but it is already
more flexible than 'upset' or 'update-setup'.  I'll probably be
switching over to using it on sourceware this week.
