The 'raw' driver without any special configuration is not needed and
creates overhead in qemu.
Stop using the 'raw' format driver in cases when it's not needed. A
special case when it is needed is for FD passed images with only a
single writable FD passed, where we need an overlay driver to properly
reflect the 'read-only' flag.

Just like we check the resulting domain XML after ATTACH and
DETACH, we should do the same after UPDATE action. This is as
simple as calling testQemuHotplugCheckResult() and providing
missing XMLs. For those test cases where no change is done, we
can just make the expected XML a symlink to the input XML.

There's a comment in testQemuHotplug() trying to explain why we
need to unlock the monitor object. Well, while it might have been
correct when being introduced, it's no longer factually correct
as just any function (attach/detach/update) might talk to the
monitor and it expects the monitor to be unlocked (as it calls
qemuDomainObjEnterMonitor() + qemuDomainObjExitMonitor()).

There's no reason for qemuhotplugtest to reimplement which device
update function to call (testQemuHotplugUpdate()) when
qemuDomainUpdateDeviceLive() already does that. Thus, drop
testQemuHotplugUpdate() and call qemuDomainUpdateDeviceLive()
directly.
BTW: this also shows why reimplementing
qemuDomainUpdateDeviceLive() is bad idea: The
"disk-cdrom-nochange" test is succeeding only because
testQemuHotplugUpdate() supports graphics and returns an
(expected) error for every other devtype.
NB, there's still missing check that the resulting XML is the
expected one (just like we do for attach and detach), but that's
pre-existing and will be fixed later.

The disk private data contain information about the tray and

removable disks thus it wasn't a problem but now when you can hotplug a
CDROM you would not be able to open its tray.
Fix it by updating the hotplugged disk the same way we do at startup.

Instead of having each test manually initialize and cleanup
its own fakerootdir, do that as part of the common test
initialization logic in virTestMain().
In most cases we can simply drop the relevant code from the
test program, but scsihosttest uses the value of fakerootdir
as a starting point to build another path, so we need to do
things slightly differently. In order to keep things working,
we retrieve the value from the LIBVIRT_FAKE_ROOT_DIR
environment variable, same as all the mock libraries are
already doing.

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 *'.
