7d9c189ac2 * src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare 
support for bit 8 in the `OS/2' table.  MS is already using this;
hopefully, this becomes part of OpenType 1.5.
Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22
(WWS_SUBFAMILY).

cf432dbf22 * include/freetype/freetype.h, src/base/ftobjs.c: renamed 
cmap14-related new APIs to the FT_Object_ActionName scheme.
        update the documentation for these APIs

        * src/sfnt/ttcmap.c: stronger cmap 14 validation, make the
        code a little more consistent with FreeType coding conventions
        and modify the cmap14 functions that returned a newly allocated
        array to use a persistent vector from the TT_CMap14 object
        instead.
