* src/autohint/ahhint.c (ah_hinter_hint_edges): Removed. Just a 

wrapper for ah_hint_edges.
(ah_hint_edges): Renamed to...
(ah_hinter_hint_edges): This.

* src/base/ftobjs.c (FT_Set_Hint_Flags): Removed.  Unused.

* include/freetype/internal/ftobjs.h (FT_Face_InternalRec),
include/freetype/internal/psaux.h (T1_DecoderRec),
src/cff/cffgload.h (CFF_Builder): Remove `hint_flags' field.
Unused.

* src/cff/cffgload.c (cff_builder_init): Updated.
(cff_decoder_parse_charstrings) <cff_op_endchar>: Call hinter->apply
with decoder->hint_mode instead of builder->hint_flags.
* src/psaux/t1decode.c (t1_decoder_init): Updated.

* src/base/ftstroker.c (ft_stroke_border_export): s/index/idx/.

* src/sfnt/sfobjs.c (sfnt_load_face): Commented out code which
increased root->height by 15% if the line gap was zero.  There exist
fonts (containing e.g. form drawing characters) which intentionally
have a zero line gap value.
