Ewald Hew 21bd9c2f8c [psaux] Fix Type 1 glyphs with too many stem hints.
According to the CFF specification, charstrings can have up to 96 stem
hints. Due to hint replacement routines in Type 1 charstrings, some
glyphs are rejected by the Adobe engine, which implements the above
limit. This fix turns off hinting for such glyphs.

* src/psaux/pshints.c (cf2_hintmap_build): Reset the error from calling
`cf2_hintmask_setAll' on a problematic Type 1 charstring and turn off
hinting.

* include/freetype/ftmm.h, src/base/ftmm.c (FT_Done_MM_Var): Declare
and define.

Werner Lemberg 2df73b397d [sfnt] Fix charmap type 2 iterator (#52646).
The subsetted demo font of the report that exhibits the bug has a
very unusual type 2 cmap for Unicode(!): It contains only two
sub-headers, one for one-byte characters (covering the range 0x20 to
0xFA), and a second one for higher byte 0x01 (just for character
code U+0131).

Before this commit, the iterator wasn't able to correctly handle a
sub-header for higher byte 0x01.

for outer loop.

Werner Lemberg 40db4a9954 Allow (again) encoding vectors with more than 256 elements (#52464).
In version 2.6.1, this has been disallowed to better reject
malformed fonts; however, this restriction was too strong.  This
time, we only take the first 256 elements into account, since
encoding arrays are always accessed with a 8bit integer, according
to the PostScript Language Reference.

* src/type1/t1load.c (parse_encoding): Implement it.
