* linux kernel (x509_cert) and process fuzzing example * rework filters * update to latest qemu * working for process and kernel fuzzing * new i2s mutator for binary only fuzzers * refactoring modules with new filtering interface * add state as parameter of harness * hide unused global in usermode * Script for stub bindings generation * do not try to check whether it is worth generating the bindings, always generate when the env variable is on. * add taplo to fmt_all.sh * Moved fuzzers (again) in a target-centric way. * fix rust 2024 warnings. * new libafl_qemu harness structure. * rename qemu_systemmode into qemu_baremetal * fix qemu baremetal makefile * fix formatter --------- Co-authored-by: Toka <tokazerkje@outlook.com>
