* src/cff/cffload.c, src/cff/cffload.h, src/cff/cffobjs.c,
src/cff/cffparse.c, src/cff/cffparse.h: Add library pointer to
'CFF_ParserRec' set by `cff_parser_init'.
Route library pointer from 'cff_face_init' to 'cff_subfont_load'
for `cff_parser_init'.

* src/cff/cffparse.c (CFF_Field_Handler): Move it to...
* src/cff/cffparse.h: This file, to be used by other C files.
