Deprecate FcName(Un)RegisterObjectTypes / FcName(Un)RegisterConstants
These never worked as intended. The problem is, if Fontconfig tries to read config files when these new types / constants are not registered, it errs. As a result, no defined types / constants are usable from config files. Which makes these really useless. Xft was the only user of this API and even there it's not really used. Just kill it. One inch closer to thread-safety since we can fix the object-type hash table at compile time.
