[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_driver_init): Don't create `TT_ExecContext' object here but ...

* src/truetype/ttinterp.c (TT_Run_Context): Remove defunct debug
code.

`TT_Driver' object.
* src/truetype/ttinterp.h: 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] Next round in phantom point handling.
Greg Hitchcock provided very interesting insights into the
complicated history of the horizontal positions of the TSB and BSB
phantom points.
* src/truetype/ttgload.c (TT_LOADER_SET_PP)
[TT_CONFIG_OPTION_SUBPIXEL_HINTING]: Use `subpixel_hinting' and
`grayscale_hinting' flags as conditionals for the x position of TSB
and BSB.

(TT_LOADER_SET_PP): The horizontal position of vertical phantom
points in pre-ClearType mode is zero, as shown in the OpenType
specification.

[truetype] Fix change from 2013-11-20.
Problem reported by Akira Kakuto <kakuto@fuk.kindai.ac.jp>.
* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Protect call to
`Update_Max' with both a TT_USE_BYTECODE_INTERPRETER guard and a
`IS_HINTED' clause.
Also remove redundant check using `maxSizeOfInstructions' – in
simple glyphs, the bytecode data comes before the outline data, and
a validity test for this is already present.

[truetype] Minor code refactoring.
Two benefits: The allocated FDEF (and IDEF) array gets slightly
smaller, and the `ttdebug' demo program has access to function
numbers without additional costs.
Fortunately, no changes to FontForge are necessary – this is the
only external TrueType debugger I know of, but others may exist and
should check the code accordingly.
* src/truetype/ttinterp.h (TT_CallRec): Replace `Cur_Restart' and
`Cur_End' with a pointer to the corresponding `TT_DefRecord'
structure.
* src/truetype/ttinterp.c (DO_JROT, DO_JMPR, DO_JROF, Ins_ENDF,

[arm] Fix thumb2 inline assembly under LLVM.
When using `ADD' with an immediate operand, the instruction is
actually `ADD Rd, Rn, #<imm12>', that is, the maximum of the
immediate operand cannot exceed 4095. It will fail to compile with
LLVM.
However, in GCC, due to some legacy compatibility considerations,
`ADD.W' will be automatically emitted when the immediate operand is
larger than 4095.

Better tracing of loaded glyphs.
Previously, the loading of a glyph was traced at level 4, if at all.
With this change, all font loading routines emit a tracing message
at level 1, making it easier to select tracing output (for example
using F2_DEBUG="any:1 afhints:7 aflatin:7").
* src/bdf/bdfdrivr.c (BDF_Glyph_Load): Add tracing message.

necessary to rewrite the code. Note, however, that it doesn't harm
if some cases are not handled since FT_THROW is a no-op.

* src/truetype/ttobjs.c (tt_size_run_prep): Reset reference points.
Up to now, we simply took a snapshot of the Graphics State after the
`prep' table has been executed, and right before a glyph's bytecode
was run it got reloaded. However, as Greg Hitchcock has told us in
private communication, reference points get reset to zero in the MS
rasterizer and we follow in due course. While reasonable, this is
undocumented behaviour.
Most notably, this fixes the rendering of Arial's `x' glyph in
subpixel hinting mode.
