function type.

[ftfuzzer] Add support for multiple files (patch #8779).
Currently, libFuzzer only supports mutation of a single file. We
circumvent this problem by using an uncompressed tar archive as
multiple-file input for the fuzzer.
This patch enables tests of `FT_Attach_Stream' and AFM/PFM parsing;
a constructed tarball should contain a font file as the first
element, and files to be attached as further elements.
* src/tools/ftfuzzer/ftfuzzer.cc: Include libarchive headers.
(archive_read_entry_data, parse_data): New functions.
(LLVMFuzzerTestOneInput): Updated.
* src/tools/ftfuzzer/ftmutator.cc: New file, providing a custom
mutator for libFuzzer that can mutate tarballs in a sensible way.

[smooth] Faster alternative line renderer.
This implementation renders the entire line segment at once without
subdividing it into scanlines. The main speed improvement comes from
reducing the number of divisions to just two per line segment, which
is a bare minimum to calculate cell coverage in a smooth rasterizer.
Notably, the progression from cell to cell does not itself require any
divisions at all. The speed improvement is more noticeable at larger
sizes.
* src/smooth/ftgrays.c (gray_render_line): New implementation.

[base] Fix a leak by broken sfnt-PS or resource fork (#46028).
open_face_from_buffer() frees passed buffer if valid font
is not found. But if copying to the buffer is failed,
the allocated buffer should be freed within the caller.
* src/base/ftobjs.c (open_face_PS_from_sfnt_stream): Free
the buffer `sfnt_ps' if an error caused before calling
open_face_from_buffer().

an error caused before calling open_face_from_buffer();

[sfnt] Better checks for invalid cmaps (2/2) (#46019).
While the current code in `FT_Get_Next_Char' correctly rejects
out-of-bounds glyph indices, it can be extremely slow for malformed
cmaps that use 32bit values. This commit tries to improve that.
* src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next,
tt_cmap12_char_map_binary, tt_cmap13_next,
tt_cmap13_char_map_binary): Reject glyph indices larger than or
equal to the number of glyphs.

fragment and total size of the concatenated POST resource
before buffer allocation.

[sfnt] Improve handling of invalid SFNT table entries (#45987).
This patch fixes weaknesses in function `tt_face_load_font_dir'.
- It incorrectly assumed that valid tables are always at the
beginning. As a consequence, some valid tables after invalid
entries (which are ignored) were never seen.
- Duplicate table entries (this is, having the same tag) were not
rejected.
- The number of valid tables was sometimes too large, leading to
access of invalid tables.
* src/sfnt/ttload.c (check_table_dir): Add argument to return number
of valid tables.
Add another tracing message.
(tt_face_load_font_dir): Only allocate table array for valid
entries as returned by `check_table_dir'.
Reject duplicate tables and adjust number of valid tables
accordingly.
