* Simple handler for signals
* add new `check-cfg` calls for libafl qemu
* Implement user-space QEMU ASAN
* Fix wrong cfgs
* fmt

* libafl_qemu: fix systemmode with slirp dependency
libslirp will be dropped from future QEMU releases (see https://wiki.qemu.org/ChangeLog/7.0).
This change adds the "slirp" feature,
which links with the host-systems libslirp.
* libafl_qemu: enable systemmode snapshots, vm_start
Re-enable snapshot functions.
Start the VM before qemu_main_loop.
* libafl_qemu: allow synchronous snapshotting
Add a flag to take snapshots synchronosly.
This should be used to take or load snapshots while the emulator is not
running.
* libafl_qemu: fallback cpu for read-/write_mem
In systemmode, current_cpu may not be set.
In such cases use the first cpus memory access methods.
* fuzzers: add example for libafl_qemu in systemmode
* libafl_qemu: update libafl-qemu-bridge revision
* libafl_qemu: add memory access by physcial address
* fix liabfl_qemu example
Use GuestAddr and physical memory access
* ci: install libslirp-dev for libafl_qemu
