Please shut down the patch tracker

[Roland McGrath]

I've disabled all the sourceforge features we're not using.  They are still
visible to logged-in group members, in case there is anything worthwhile to
dig out from the old entries.  This mailing list is the only forum that is
really worth having for exchanging patches and such.  People already file
bug reports in the Fedora and Debian systems, and that's more than enough.


Thanks,
Roland
