If the QEMU driver is configured to use the old "file" stdio
handler (meaning virtlogd is out of the picture) and a chardev
has a log file configured we rely on QEMU being able to create
the file itself. This may not be always possible (e.g. if the
logfile is set to a directory that QEMU process can't reach).
In such case we should create the file and just pass its FD to
QEMU.
We could do that unconditionally and just either pass FD from
virtlogd or the one we opened, because we bumped QEMU version
and are now requiring new enough QEMU. However, I'm keeping the
old style where logfile is appended on the cmd line for the tests
sake.

If guest is configured to use memfd then the function that build
memory-backend-* part of command line will put
memory-backend-memfd, always. Even for NVDIMMs. This is not
correct, because NVDIMMs need a backing path (usually to a real
host NVDIMM device). Therefore, regardless of memfd being
requested, we have to stick with memory-backend-file.

Implement this behaviour by skipping the disks on traditional
commandline and hotplug them before resuming CPUs. That allows to use
the support for hotplugging of transient disks which inherently allows
sharing of the backing image as we open it read-only.
This commit implements the validation code to allow it only with buses
supporting hotplug and the hotplug code while starting up the VM.
When we have such disk we need to issue a system-reset so that firmware
tables are regenerated to allow booting from such device.

Historically, we declared pointer type to our types:
typedef struct _virXXX virXXX;
typedef virXXX *virXXXPtr;
But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.
