This is a continuation of a similar patch from 2020-12-02, which
missed some locations.

We no longer have to take care of the 8.3 file name limit; this
allows us (a) to introduce longer, meaningful file names, and (b) to
avoid macro names in `#include' lines altogether since some
compilers (most notably Visual C++) doesn't support this properly.
*/*: Replace
#include FOO_H
with
#include <freetype/foo.h>
or something similar. Also update the documentation.
642bc7590c introduced dynamically
allocated memory when parsing CFF files with the "old" engine. Bounds
checks have never been updated, however, leading to pointless
comparisons of pointers in some cases. This commit presents a
solution for bounds checks in the CFF module with an extended logic
for the "old" engine while staying as concise as possible for the
"new" one.
* src/cff/cffparse.h: Introduce the struct `CFF_T2_StringRec' and
the additional field `t2_strings' within `CFF_ParserRec'.
* src/cff/cffparse.c (cff_parser_within_limits): Move all boundary
checks into this new function and update the rest of `cffparse.c' to
use it.

This monster commit was created by applying Nikhil's scripts
`docconverter.py' and `markify.py' to all C header and source files,
followed up by minor manual clean-up.
No change in functionality, of course.
I used commit f7419907bc6044b9b7057f9789866426c804ba82 from
https://github.com/nikramakrishnan/freetype-docs.git.

PIC mode or an array in non-PIC mode) with `xxx' arrays.

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.

CFF_VStore, CFF_Blend): New structures.
(CFF_FontRecDict): Add `vstore_offset' field.
(CFF_Private): Add `vsindex' field.
(CFF_SubFont): Add fields for blend data.
(CFF_Font): Add `vstore' field.
* src/truetype/ttgxvar.c (TT_Get_MM_Var): `CFF2' is equal to `gvar',
since glyph variation data is directly embedded.

* include/freetype/config/ftstdlib.h (FT_LONG_MIN): New macro.
* src/cff/cffparse.c (cff_parse_font_matrix): Use largest scaling
value of all matrix coefficients to scale matrix.
* src/cff/cffobjs.c (cff_face_init): Use `matrix->yx' member for
matrix normalization if `matrix->yy' is zero.
Now all glyphs of MM CFFs like `ITCGaramondMM-It.otf' can be
displayed.
* src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_store,
cff_op_load>: Partially implement it.
* src/cff/cffparse.c (cff_parser_init): Add new parameter to pass
the number of Multiple Master axes.
Update all callers.
