466658fc52 Sync Exit: 
- Now the VM can trigger a synchronous backdoor stopping the VM and returning to LibAFL.
- LibAFL will exit with a corresponding exit reason to perform actions accordingly (checkout the LibAFL patch for more details).
- The breakpoint mechanism has been merged with this system (not tested yet, may not work out of the box).
- The main difference with the backdoor is that it will always stop the VM.

e2faabee78 accel/tcg: Forward probe size on to notdirty_write 
Without this, we just dirty a single byte, and so if the caller writes
more than one byte to the host memory then we won't have invalidated any
translation blocks that start after the first byte and overlap those
writes. In particular, AArch64's DC ZVA implementation uses probe_access
(via probe_write), and so we don't invalidate the entire block, only the
TB overlapping the first byte (and, in the unusual case an unaligned VA
is given to the instruction, we also probe that specific address in
order to get the right VA reported on an exception, so will invalidate a
TB overlapping that address too). Since our IC IVAU implementation is a
no-op for system emulation that relies on the softmmu already having
detected self-modifying code via this mechanism, this means we have
observably wrong behaviour when jumping to code that has been DC ZVA'ed.
In practice this is an unusual thing for software to do, as in reality
the OS will DC ZVA the page and the application will go and write actual
instructions to it that aren't UDF #0, but you can write a test that
clearly shows the faulty behaviour.

For functions other than probe_access it's not clear what size to use
when 0 is passed in. Arguably a size of 0 shouldn't dirty at all, since
if you want to actually write then you should pass in a real size, but I
have conservatively kept the implementation as dirtying the first byte
in that case so as to avoid breaking any assumptions about that
behaviour.

cf9b5790db accel/tcg: Remove CF_LAST_IO 
In cpu_exec_step_atomic, we did not set CF_LAST_IO, which lead
to a loop with cpu_io_recompile.

But since 18a536f1f8 ("Always require can_do_io") we no longer
need a flag to indicate when the last insn should have can_do_io set,
so remove the flag entirely.

d12a91e0ba target/s390x/arch_dump: Add arch cleanup function for PV dumps 
PV dumps block vcpu runs until dump end is reached. If there's an
error between PV dump init and PV dump end the vm will never be able
to run again. One example of such an error is insufficient disk space
for the dump file.

Let's add a cleanup function that tries to do a dump end. The dump
completion data is discarded but there's no point in writing it to a
file anyway if there's a possibility that other PV dump data is
missing.
