Ugly hack to extend rpmbuild's auto-requires to process handler.pl.  This is loosely based on notes on the Fedora wiki.  The internal dependency generator is disabled and as far as possible the same code is used to generate provides and requires.  The list of files to be scanned for requires is saved by a supplemental script and if it contains handler.pl, that file is scanned for requires with the standard Perl dependencies checker.  References to RT are filtered out as RT is not enabled in this version of the .spec file.  This mod obsoletes the freeside-mason-deps.inc file and simplifies building the RPMs.
