Update bundled Freetype to 2.10.4
Removed everything, imported with help of import_from_tarball.sh script,
and then added a pre-generated builds/unix/ftconfig.h
This also amends 58f56950848bae9c90da3873090c7698e0128b12 because it is
not a clean update, some old files are still there.
Also redo the fix for wasm like 30f4ca4e4fbc1d8cf86808dbeb00ec3c046f6c1c.
Fixes: QTBUG-82480
Pick-to: 6.2
Change-Id: I45ee3230299908ca0372e035636dd64b6c549a27

It can be -used with libFuzzer (https://llvm.org/docs/LibFuzzer.html) or -potentially any other similar fuzzer. - -Usage: - - 1. Build `libfreetype.a' and `ftfuzzer.cc' using the most recent - clang compiler with these flags: - - # for fuzzer coverage feedback - -fsanitize-coverage=edge,8bit-counters - # for bug checking - -fsanitize=address,signed-integer-overflow,shift - - You also need the header files from the `libarchive' library - (https://www.libarchive.org/) for handling tar files (see file - `ftmutator.cc' below for more). - - 2. Link with `libFuzzer' (it contains `main') and `libarchive'. - - 3.

The main usage is to load AFM files -for PostScript Type 1 fonts. - -However, libFuzzer currently only supports mutation of a single input -file. For this reason, `ftmutator.cc' contains a custom fuzzer -mutator that uses an uncompressed tar file archive as the input.
