[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_GETVARIATION) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: New function

[truetype] Support selector index 3 of the INSTCTRL instruction.
This flag activates `native ClearType hinting', disabling backwards
compatibility mode as described in Greg Hitchcocks whitepaper. In
other words, it enables unrestricted functionality of all TrueType
instructions in ClearType.
* src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks'
unconditionally.
(tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of
`GS.instruct_control' is active.
* src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3.
(Ins_GETINFO): Updated.

[truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver.
Previously the code had stipulation for using a per-TT_Size exec
context if `size->debug' was true. But there was no way that
`size->debug' could *ever* be true. As such, the code was always
using the singleton `TT_ExecContext' that was stored in `TT_Driver'.
This was, clearly, not threadsafe.
With this patch, loading glyphs from different faces from different
threads doesn't crash in the bytecode loader code.
* src/truetype/ttobjs.h (TT_SizeRec): Remove `debug' member.
(TT_DriverRec): Remove `context' member.
* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Remove
`TT_ExecContext' code related to a global `TT_Driver' object.
(tt_driver_done): Don't remove `TT_ExecContext' object here but ...
(tt_size_done_bytecode): ... here.
(tt_driver_init): Don't create `TT_ExecContext' object here but ...
(tt_size_init_bytecode): ... here, only on demand.
* src/truetype/ttinterp.c (TT_Run_Context): Remove defunct debug
code.
(TT_New_Context): Remove `TT_ExecContext' code related to a global
`TT_Driver' object.
* src/truetype/ttinterp.h: Updated.
* src/truetype/ttgload.c (TT_Hint_Glyph, tt_loader_init): Updated.

* src/truetype/ttinterp.c (Ins_DELTAP): Fix subpixel hinting.
Before this patch, it was impossible to ever call DELTAP[123] in
subpixel hinting mode as described in the ClearType whitepaper; it
only worked if in `compatibility mode'. However, compatibility mode
essentially disables SHPIX, completely ruining hinting of
ttfautohint output, for example.
We now follow the whitepaper more closely so that DELTAP[123]
instructions for touched points in the non-subpixel direction are
executed.

[truetype] Improve handling of buggy `prep' tables.
In case of an error in the `prep' table, no longer try to execute it
again and again. This makes FreeType handle endless loops in buggy
fonts much faster.
* src/truetype/ttobjs.h (TT_SizeRec): The fields `bytecode_ready'
and `cvt_ready' are now negative if not initialized yet, otherwise
they indicate the error code of the last run.
