Guidance on how to update libafl_qemu code about libafl HOT 3 CLOSED

@rmalmain Thank you so much for taking a look and writing up this detailed guidance!

@rmalmain can you give som info?

Now, Emulator is split into 2 different structures:

• Qemu: The low-level struct. It is initialized by calling Qemu::init like the old Emulator::new and mostly consists of native calls to qemu. It resembles a lot the old Emulator you used back in the time. An example systemmode fuzzer is available here.
• Emulator: the high-level struct. It is intended to be used as an abstraction of Qemu to avoid writing boilerplate code (like set / unset breakpoint by hand for example). You can find 2 variations of the previous fuzzer using this abstraction here and here.

So, from what I can see in the link you sent, most things should work out of the box if you replace Emulator with Qemu, modulus some minor changes.

About the pub fn start(&self, cpu: &CPU), it has been replaced with pub unsafe fn run(&self) in the Qemu struct. You can find more details there.
