Move creation of field `buildchar' of T1_DecoderRec out of 

`t1_decoder_init' and let the caller of `t1_decoder_init' take care
of it.

Call the finisher for T1_Decoder in `cid_face_compute_max_advance'
and `T1_Compute_Max_Advance'.

* freetype2/include/freetype/internal/psaux.h (T1_DecoderRec):
Remove field `face', add `len_buildchar'.

* freetype2/include/freetype/internal/t1types.h (T1_FaceRec): Add
field `buildchar'.

* freetype2/src/cid/cidgload.c (cid_face_compute_max_advance): Call
finisher for T1_Decoder.
(cid_slot_load_glyph): Do not ignore failure when initializing the
T1_Decoder.

* freetype2/src/psaux/t1decode.c (t1_decoder_parse_charstrings):
Updated.
(t1_decoder_init): Remove initialization of fields `buildchar' and
`len_buildchar'.
(t1_decoder_done): Remove deallocation of field `buildchar'.

* freetype/src/type1/t1gload.c (T1_Compute_Max_Advance): Initialize
T1_Decoder's `buildchar' and `len_buildchar'; call finisher for
T1_Decoder.
(T1_Load_Glyph): Initialize T1_Decoder's `buildchar' and
`len_buildchar'; make sure to call finisher for T1_Decoder even in
case of error.

* freetype2/src/type1/t1load.c (T1_Open_Face): Allocate new field
`buildchar' of T1_FaceRec.

* freetype2/src/type1/t1objs.c (T1_Face_Done): Free new field
`buildchar' of T1_FaceRec.
