Subject: [PATCH] [psaux] Change subfont synthesis for CID fonts.

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.
