When dynamic-reconfiguration is off, hot plug / unplug can fail with
"Bus 'spapr-pci-host-bridge' does not support hotplugging".
spapr-pci-host-bridge is a device, not a bus. Report the name of the
bus it provides instead: 'pci.0'.

Like replay_linux.py, reverse_debugging.py starts the vm with console
set but does not interact with it (e.g., with wait_for_console_pattern).
In this situation, the console should have a drainer attached so the
socket does not fill. replay_linux.py has a drainer, but it is missing
from reverse_debugging.py.
Per analysis in Link: this can cause the console socket/pipe to fill and
QEMU get stuck in qemu_chr_write_buffer, leading to strange test case
failures (ppc64 fails because it prints a lot to console in early bios).
Attaching a drainer prevents this.
Note, this commit does not fix bugs introduced by the commits referenced
in the first two Fixes: tags, but together those commits conspire to
irritate the problem and cause test case failure, which this commit
fixes.

In a perfect world we'd have reproducible tests,
but then we'd be sure we run the same binaries.
If a binary artifact isn't hashed, we have no idea
what we are running. Therefore enforce hashing for
all our artifacts.
With this change, unhashed artifacts produce:

The "edid" feature has been added to vhost-user-gpu in commit
c06444261e ("contrib/vhost-user-gpu: implement get_edid feature"),
so waiting for "features: +virgl -edid" in the test does not work
anymore, it's "+edid" instead of "-edid" now!
While we're at it, move the expected string to the preceeding
exec_command_and_wait_for_pattern() instead (since waiting for
empty string here does not make too much sense).

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.
