include/freetype/internal/psnames.h (removed),
include/freetype/internal/internal.h (FT_SERVICE_POSTSCRIPT_NAMES):
added new service to handle glyph name dictionaries, replacing
the old internal header named "psnames.h" by "services/svpsname.h"
note that this is different from "services/svpostnm.h" which only
handles the retrieval of Postscript font name for a given face.
(should we merge these two services into a single header ??)
* include/freetype/internal/ftserv.h: adding
FT_FACE_FIND_GLOBAL_SERVICE (used to lookup a service globally,
instead of only within the current module)
* include/freetype/internal/ftobjs.h, src/base/ftobjs.c: adding
the new base function ft_module_get_service
