Use implementation specific SID value 0xFFFF to indicate that 

a dictionary element is missing.

* src/cff/cffload.c (cff_subfont_load): Initialize all fields
which hold SIDs to 0xFFFF.
(cff_index_get_sid_string): Handle SID value 0xFFFF.
Handle case where `psnames' is zero.
(cff_font_load): Updated.
Don't load encoding for CID-keyed CFFs.

* src/cff/cffobjs.c (cff_face_init): Updated.
Don't check for PSNames module if font is CID-keyed.
Compute style name properly (using the same algorithm as in the
CID driver).
Fix computation of style flags.

* src/cff/cfftoken.h: Comment out handling of base_font_name.
Rename `postscript' field to `embedded_postscript'
* src/cff/cfftypes.h (CFF_FontRecDictRec): Remove `base_font_name'
and `postscript'.
