Asserting the value we set four lines earlier in qemuBlockjobState
doesn't buy us any safety (if the public header adds a value, we end
up skipping that value without the compiler warning us of our gap);

Instead of hardcoding the TLS creds alias in

Given that we only support one VNC graphics

to prepare the secret upfront when we start
supporting encrypted server TLS keys.
Note that the alias is not formatted anywhere
since we won't need to access it after domain
startup.

If a -drive has no image, using image properties makes qemu whine that
they should not be used.
This patch stops formating cache/readonly/... for empty drives
for the pre-blockdev syntax. Unfortunately those parameters can't be
added later when inserting media, but on the other hand qemu will start
with an empty drive.
Since we already were able to start a VM with such config previously due
to qemu ignoring them I've opted just to skip formatting them.
Additionally with -blockdev support it will work as expected as the
image properties will be formatted when adding the image itself which is
not possible without it.

When commit 361c8dc17 added support for hotplugging the i6300esb
watchdog device (first in libvirt-3.9.0), it accidentally contstructed
the commandline for the device_add command before allocating a PCI
address for the device. With no PCI address specified in the command,
the watchdog would simply be placed at the lowest unused PCI slot.
On a 440fx guest, this doesn't cause a problem, because libvirt's PCI
address allocation algorithm would most likely give the same address
anyway (usually a slot on pci-root), so nobody noticed the omission of
address from the command.
But on a Q35 guest, the lowest unused PCI slot is on pcie-root, which
doesn't support hotplug; libvirt knows enough to assign a PCI address
that is on a pcie-to-pci-bridge (because its slots *do* support
hotplug), but qemu doesn't, so if there is no PCI address in the
command, qemu just tries to plug the new device into pcie-root, and
fails because it doesn't support hotplug, e.g.:
error: Failed to attach device from watchdog.xml
error: internal error: unable to execute QEMU command 'device_add':
Bus 'pcie.0' does not support hotplugging
The solution is simply to build the command string after assigning a
PCI address, not before.
