    Remove shared-str pool
    
    We used to have a shared-str pool.  Removed to make thread-safety
    work easier.  My measurements show that the extra overhead is not
    significant by any means.

    Use a static perfect hash table for object-name lookup
    
    Generated by gperf.  A bit fragile, but I think I got it all right.

    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.
