* src/pfr/pfrobjs.c, src/pfr/pfrobjs.h (pfr_face_init, 

pfr_face_done, pfr_face_get_kerning, pfr_slot_init, pfr_slot_done,
pfr_slot_load): Don't use PFR_XXX but FT_XXX arguments which are
typecast to the proper PFR_XXX types within the function.
Update code accordingly.

* src/pfr/pfrdrivr.c (pfr_get_kerning, pfr_get_advance,
pfr_get_metrics, pfr_get_service): Don't use PFR_XXX but FT_XXX
arguments which are typecast to the proper PFR_XXX types within the
function.
Update code accordingly.
Use FT_CALLBACK_DEF throughout.
(pfr_metrics_service_rec, pfr_driver_class): Remove casts.
