gnats -> bugzilla

[Tom Tromey]

Hi everyone.

I'd like gdb to switch from gnats to bugzilla.  Gnats is showing its
age and is annoying to use.  I think this is a contributing factor to
the under-reporting of gdb bugs and general under-use of the gdb bug
tracker.

My general plan is:

* Write a patch for the documentation and the web site.

* Disable Gnats.

* Get gnats2bz and convert the current database.
  This will renumber all the bugs; I don't consider this a major
  problem.

* Get DannyB to upload this into the current sourceware bugzilla
  instance and check in all the changes.

* Archive the Gnats database.


If you have any objections, speak up.

Tom
