  Add support for the hexadicimal representation of binary data
  started with `StartData' in CID-keyed Type 1 fonts.
  
  * include/freetype/internal/t1types.h (CID_FaceRec): Add new
  members `binary_data' and `cid_stream'.
  
  * src/cid/cidload.c (cid_read_subrs): Use `face->cid_stream'.
  (cid_hex_to_binary): New auxiliary function.
  (cid_face_open): Add new argument `face_index' to return quickly
  if less than zero.  Updated all callers.
  Call `cid_hex_to_binary', then open and assign memory stream to
  `face->cid_stream' if `parser->binary_length' is non-zero.
  * src/cid/cidload.h: Updated.
  
  * src/cid/cidobjs.c (cid_face_done): Free `binary_data' and
  `cid_stream'.
  
  * src/cid/cidparse.c (cid_parser_new): Check arguments to
  `StartData' and set parser->binary_length accordingly.
  * src/cid/cidparse.h (CID_Parser): New member `binary_length'.
  
  * src/cid/cidgload.c (cid_load_glyph): Use `face->cid_stream'.
  
  * docs/CHANGES: Updated.
  
  
  include/freetype/config/ftstdlib.h (ft_atoi): Replaced with...
  (ft_atol): This.
  * src/base/ftdbgmem.c: s/atol/ft_atol/.
  * src/type42/t42drivr.c: s/ft_atoi/ft_atol/.
