[Fontconfig] Ready for fontconfig 2.2?

[Keith Packard]

The bug list is nearly empty (except for questions about fontconfig.spec.in)
and I've moved the file pattern accept/reject code until 2.3.  It looks 
like fontconfig ready for release.

Please post a note if there are still outstanding issues that need 
resolution before we can ship this thing.  Otherwise, I'll tag and release 
sometime tomorrow.
