We simply terminate qemu instead of issuing a reset as the semantics of
the setting dictate.
Fix it by handling it identically to 'fake reboot'.
We need to forbid the combination of 'onReboot' -> 'destroy' and
'onPoweroff' -> reboot though as the handling would be hairy and it
honetly makes no sense.

The qemu driver didn't ever implement any meaningful handling for the
'rename-restart' action.
At this point the following handling would take place:
'on_reboot' set to 'rename-restart' is ignored on guest-initiated
reboots, the guest simply reboots.
For on_poweroff set to 'rename-restart' the following happens:
guest initiated shutdown -> 'destroy'
libvirt initiated shutdown -> 'reboot'
In addition when 'on_reboot' is 'destroy' in addition to 'on_poweroff'
being 'rename-restart' the guest is able to execute instructions after
issuing a reset before libvirt terminates it. This will be addressed
separately later.
Forbid the flag in the qemu def validator and update the documentation
to be factual.

Use the larger number in the original test to avoid having two files.
Additionally this avoids use of 'host-model' with DO_TEST_CAPS_LATEST in
cases when it isn't necessary for the purpose of the test as the CPU
model tends to change.

Reviewed-by: Kristina Hanicova <khanicov@redhat.com>
New clang has a false-positive about value of 'olddisks' being unused
after being set. This is clearly wrong because we want to use
'g_autofree' to clear it later.
While I'm against modifying good code for the sake of bad static
analysis in this case it's not obvious that we depend on the lifetime of
'olddisks' being needed until the end of the function as we store
pointers into it into the hash table and later copy them out.
Rewrite the code by assigning to 'olddisks' earlier and then using
'olddisks' in the loop, so it's clear where the lifetime of the objects
ends, and this should also silence the warning.
