Change subfont synthesis for CID fonts.

Browse Source 
Change `t1_make_subfont' to take in the Private dict record as an
argument.  This is because Type 1 and CID font records in FreeType
have this in different places.

* src/psaux/psobjs.c (t1_make_subfont): Change `T1_Face' to
`FT_Face' so that CID is also accepted.
Take `PS_Private' as an argument and let caller figure out where the
Private dict actually is.
Update references.

* include/freetype/internal/psaux.h, src/psaux/psobjs.h: Update
declaration.

* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Update
call.
