[truetype] Improve the recursive reference detector.
The previous fix for #46372 misunderstood a composite glyph referring
same component twice as a recursive reference. See the discussion

Thanks to Khaled Hosny for finding this issue.

the i-th node from FT_List. (load_truetype_glyph): In the traversal

nodes filled by previous sibling chain.

Make Jam support work again.
This is just very basic stuff and just a little bit tested on
GNU/Linux only. I won't delve into this since I'm not a Jam user.
* Jamfile: Call `HDRMACRO' for `ftserv.h' also.
(DEFINES): Replace with...
(CCFLAGS): ... this.
* src/Jamfile: Don't call `HDRMACRO' for `internal.h'; this is
already handled in the top-level Jamfile.
* src/autofit/Jamfile (DEFINES): Replace with...
(CCFLAGS): ... this.
(_sources): Add missing files.
* src/cache/Jamfile: Don't call `HDRMACRO' for `ftcache.h'; it no
longer contains macro header definitions.
* src/base/Jamfile, src/cff/Jamfile, src/sfnt/Jamfile,
src/truetype/Jamfile (_sources): Add missing files.

[truetype] Fix memory leak.
Problem reported by Grissiom <chaos.proton@gmail.com>; in

[truetype] In GX, make private point numbers work correctly.
This is completely missing in Apple's documentation: If a `gvar'
tuple uses private point numbers (this is, deltas are specified for
some points only), the uncovered points must be interpolated for
this tuple similar to the IUP bytecode instruction. Examples that
need this functionality are glyphs `Oslash' and `Q' in Skia.ttf.
* src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate,
tt_handle_deltas): New functions.
(TT_Vary_Get_Glyph_Deltas): Renamed to...
(TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the
points and does no longer return an array of deltas.
Add tracing information.
Call `tt_handle_deltas' to interpolate missing deltas.
Also fix a minor memory leak in case of error.
* src/truetype/ttgxvar.h: Updated.
* src/truetype/ttgload.c (TT_Process_Simple_Glyph,
load_truetype_glyph): Updated.

other words, it enables unrestricted functionality of all TrueType
instructions in ClearType.
* src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks'
unconditionally.

[truetype] Fix loading of composite glyphs.
* src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the
ARGS_ARE_XY_VALUES flag is not set, handle argument values as
unsigned. I trust `ttx' (which has exactly such code) that it does
the right thing here...
The reason that noone has ever noticed this bug is probably the fact
that point-aligned subglyphs are rare, as are subglyphs with a
number of points in the range [128;255], which is quite large (or
even in the range [32768;65535], which is extremely unlikely).

[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 ...

* 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.
