Bug 192516: Moving the loose .pm files into the Bugzilla directory, where they belong.  These files pre-date the Bugzilla directory, and would have gone there had it existed at the time.  The four files in question were copied on the CVS server to preserve CVS history in the files.  This checkin deletes them from the old location and modifies everything else to know where they are now.
