For example, we can export WINFNT.  Then instead of calling
"FT_Get_WinFNT_Header", which is simply a wrapper, client can call
"FT_Find_Service" to request the service directly.

Same other services, like OPENTYPE_VALIDATE, GLYPH_DICT,
POSTSCRIPT_FONT_NAME, etc., are also ready to be exported.

We now call "FT_FACE_FIND_SERVICE( GLYPH_DICT )" to find a service.
After the change, we still call "FT_FACE_FIND_SERVICE( GLYPH_DICT )" to
find a service.  So most part of the library won't know the differences,
except "ft_service_list_lookup".  This may be of some importance when
trying to find a global service.
