[pcf] Make long family names configurable.
The change from 2016-09-29 was too radical (except for people using
the openSuSE GNU/Linux distribution). To ameliorate the situation,
PCF_CONFIG_OPTION_LONG_FAMILY_NAMES gets introduced which controls
the feature; if set, a new PCF property option
`no-long-family-names' can be used to switch this feature off.
* include/freetype/config/ftoption.h, devel/ftoption.h
(PCF_CONFIG_OPTION_LONG_FAMILY_NAMES): New option.
* include/freetype/ftpcfdrv.h: New header file (only containing
comments currently, used for building the documentation).

[truetype] Fix linear metrics of GX variation fonts.
When asking for an unhinted non-default variations,

need sane fallback.

[cff] Implement CFF2 support (2/2).
The font variation code. All parts dependent on the GX code in the
`truetype' module are guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT.
In other words, you can still compile the `cff' module without
defining TT_CONFIG_OPTION_GX_VAR_SUPPORT (which brings you CFF2
support without font variation).
* src/cff/cf2font.c (cf2_font_setup): Add support for font
variation.
* src/cff/cf2font.h (CF2_Font): Add fields for variation data.
* src/cff/cf2ft.c (cf2_free_instance): Free blend data.

(cff_font_load): Handle CFF2 variation store data.
(cff_font_done): Updated.
* src/cff/cffload.h: Include `cffparse.h'.
Updated.
* src/cff/cffobjs.c (cff_face_done): Updated.
* src/cff/cffparse.c: Include `cffload.h'.
(cff_parse_num): Handle internal value 255.
