[truetype] Fix linear metrics of GX variation fonts.

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.

defining TT_CONFIG_OPTION_GX_VAR_SUPPORT (which brings you CFF2
support without font variation).

variation.
* src/cff/cf2font.h (CF2_Font): Add fields for variation data.
* src/cff/cf2ft.c (cf2_free_instance): Free blend data.

[truetype] Sanitize only last entry of `loca' table.
Without this patch, a loca sequence like `0 100000 0 100000 ...',
where value 100000 is larger than the `glyf' table size, makes
FreeType handle the whole `glyf' table as a single glyph again and
again, which is certainly invalid (and can be very slow, too).
* src/truetype/ttpload.c (tt_face_get_location): Implement.
Improve tracing messages.

[truetype] Add bytecode support for GX variation fonts.
This commit implements undocumented (but confirmed) stuff from
Apple's old bytecode engine.
GETVARIATION[], opcode 0x91
This opcode pushes normalized variation coordinates for all axes
onto the stack (in 2.14 format). Coordinate of first axis gets
pushed first.
GETINFO[], selector bit 3
If GX variation support is enabled, bit 10 of the result is set
to 1.
* src/truetype/ttinterp.c: Include FT_MULTIPLE_MASTERS_H.
(opcode_name) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Updated.
(Ins_GETINFO) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle selector
bit 3, checking support for variation glyph hinting.
(Ins_GETVARIATION) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: New function
to implement opcode 0x91.
(TT_RunIns) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle opcode 0x91.
