while perl returns the (scalar) result of the last expression
automatically its still nicer to explicitly do so..

this allows a user to set a drive to 'read-only'. This can be useful
if a disk should not be written to, or if the backing file/source is
not writable (like a mapped pbs backup to /dev/loopX).
the option is named 'ro', to achieve consistency with containers
while this could also be achieved by setting 'snapshot=1', this would
create a temporary file in /var/tmp which can get quite big.

ovmf with SMM enabled will not boot on i440fx (hangs on graphics
initialization), so load the non SMM variant.

swtpm may take a little bit to daemonize, so the pidfile might not be
available right after run_command. Causes an ugly warning about using an
undefined value in a match, so wait up to 5s for it to appear.
Note that in testing this loop only ever got to the first or second
iteration, so I believe the timeout duration should be more than enough.
Also add a missing 'usleep' import, 'usleep' was used before but never
imported, apparently the other case never got triggered...

QEMU doesn't know about the tpmstate, so 'do_snapshots_with_qemu' should
never return true in that case. Note that inconsistencies related to
snapshot timing do not matter much, as the actual TPM data is exported
together with other device state by QEMU anyway.

`properties` is a bit ambiguous and as we have scope and start
runtime properties in the same scope it's good to avoid that
ambiguity.

on vm start, we reserve all pciids that we use, and
remove the reservation again in vm_stop_cleanup
first with only a time-based reservation but after the vm is started,
we reserve again but with the pid.
for this, we have to move the start_timeout calculation above the
hostpci handling.
also moved the pci initialization out of the conf parsing loop
so that we can reserve all ids before we actually touch any of them
while touching the lines, fix the indentation
this way, when a vm starts with a pci device that is already configured
for a different running vm, will not be started and the user gets
the error that the device is already in use

both style and readability are naturally subjective to a certain
degree...
Also, this patch mixes a bit much into one thing, but splitting that
up would mean lots of work I just wanted to avoid, sorry about that.
Among other things:
- avoid a level of indentation in the reserve loop
- rename pciids to reservation_list where it was a better fit
- make reserve set either pid or time to avoid suggesting that we
save both
- rename parameters to requested/dropped IDs for easier understanding
what's going on in the code
- avoid old_pid/pid, use running_pid and reserver_pid instead to
clarify what they actually mean
- drop useless returns to avoid suggesting the return value has any
use and save some lnes
- use a hash slice to delete all dropped IDs at once, shorter and
faster
- use 5 second timeout for reservation, this does nothing intensive
nor does it wait for anything, so the critical section should be
really short, 5s is really long enough for a wait..

lck needs to die, the days of any 8.3 file naming schemes are long
gone (in the server space that is ;)
/var/run is /run so use the shorter, and while /var/lock is a OK
place for the locks we try to keep lock and lock-object together
nowadays. The qemu-server sub-directory avoids overly cluttering the
already crowded top-level /run dir

saves a list of pciid <-> vmid mappings in /var/run
that we can check when we start a vm
if we're not given a pid but a timeout, we save the time when the
reservation will run out (current time + timeout + 5s) since each
vm start (until we can save the pid) varies from config to config
reserve_pci_usage and remove_pci_reservation always expect a list of ids
so that we can update the reservation for a vm all at once
