Save and restore CPU state in libafl_qemu (#907)
* 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

* fuzzers/qemu_systemmode: clean up example

* libafl_qemu: remove obsolete functions

emu::libafl_cpu_thread_fn
emu::libafl_start_vcpu
emu::start

* fuzzers/qemu_systemmode: simplify example

* improve build_linux.rs

* Update qemu_systemmode fuzzer
