Largest change is in the FFI crate.
With 2024 (but not 2021) edition unsafe code
inside unsafe functions should be marked separately
so we can mark exactly the code that is unsafe.
Some CFFI functions even have no unsafe code inside.
Most interesting change is that .strdup()
functions are not marked as unsafe anymore.
They are allocating memory and return raw pointers,
but there is nothing unsafe about it.
Only using the returned raw pointers is unsafe.
This way calls to .strdup() don't have to be marked
with unsafe{} blocks.
New `fuzz` profile is added
because cargo-bolero now requires it and uses
by default, while `--release` option is removed.
Instructions for running AFL are removed from the README
because it requires some system reconfiguration
and I did not test it this time.
Say in the README that cargo-bolero@0.8.0
should be installed as newer versions
do not work currently.
Update `mailparse` to 0.16.0
because this is what Delta Chat currently uses.
I also added fuzzer outputs to .gitignore
