bump versioned build-dependency, as qemu-server has tests checking

if the user set a device as hostpci with the 'shorthand' syntax:
hostpciX: 00:12
we ignored it on starting and showcmd and continued.
Since the user explicitly wanted to passthrough a device, we now check
if there is actually a device with that id
for explicitly configured devices (00:12.1), we did not check if it exists,
but the kvm call failed with a non-obvious error message
now we always call 'lspci' from SysFSTools to check if it actually exists,
and fail if not. With this, we can drop the workaround for adding
'0000' if no domain was given, since lspci does it already for us
this fixes#2510, an issue with using mediated devices where the users did not have
the domain in the config, since we forgot to add the default domain there
the only issue with this patch is that it changes the behaviour of
'showcmd' slightly, as in now, we die if the device was explicitly
given, but did not exists (we showed the commandline, now we fail)
this also slightly changes the commandline for qemu (adding always
the domain), which is not a problem since we cannot live migrate
or snapshot such vms, but we have to adapt the tests

With our QEMU 4.1.1 package we can pass a additional internal version
to QEMU's machine, it will be split out there and ignored, but
returned on a QMP 'query-machines' call.
This allows us to use it for increasing the granularity with which we
can roll-out HW layout changes/additions for VMs. Until now we
required a machine version bump, happening normally every major
release of QEMU, with seldom, for us irrelevant, exceptions.
This often delays rolling out a feature, which would break
live-migration, by several months. That can now be avoided, the new
"pve-version" component of the machine can be bumped at will, and
thus we are much more flexible.
That versions orders after the ($major, $minor) version components
from an stable release - it can thus also be reset on the next
release.
The implementation extends the qemu-machine REGEX, remembers
"pve-version" when doing a "query-machines" and integrates support
into the min_version and extract_version helpers.
We start out with a version of 1.

QMP and monitor helpers are moved from QemuServer.pm.
By using only vm_running_locally instead of check_running, a cyclic
dependency to QemuConfig is avoided. This also means that the $nocheck
parameter serves no more purpose, and has thus been removed along with
vm_mon_cmd_nocheck.
Care has been taken to avoid errors resulting from this, and
occasionally a manual check for a VM's existance inserted on the
callsite.
Methods have been renamed to avoid redundant naming:
* vm_qmp_command -> qmp_cmd
* vm_mon_cmd -> mon_cmd
* vm_human_monitor_command -> hmp_cmd
mon_cmd is exported since it has many users. This patch also changes all
non-package users of vm_qmp_command to use the mon_cmd helper. Includes
mocking for tests.

vm_exists_on_node in PVE::QemuConfig checks if a config file for a vmid
exists
vm_running_locally in PVE::QemuServer::Helpers checks if a VM is running
on the local machine by probing its pidfile and checking /proc/.../cmdline
check_running is left in QemuServer for compatibility, but changed to
simply call the two new helper functions.
Both methods are also correctly mocked for testing snapshots.

The reason for why we did not do this in the first place was the fact
that the "usb3" flag could be set in older qemu-server versions, we
just ignored it but not filtered it out of the config..
That means there can be VMs out there which would now become a
different HW layout, and issue for migration and live-snapshot
restore.
But, actually, while the "usb3" property could be set it allowed to
start the VM in only if an additional USB devices was added to the VM
with USB2, or the VM uses "q35" based machine - as else no "ehci" was
available, and thus the "ignored" USB3 - SPICE could not get attached
anywhere -> QEMU chickened out.
And if a user had a configuration where this could started we have
still a bit luck, live-migration was not possible as the "can't
migrate VM which uses local devices:" check still hit, as in
qemu-server older than 6.0-8 we explicitly checked for "spice" when
seeing what usb device were not local, so a "spice,usb3=X" was always
(luckily) wrongly detected as local device -> migration was blocked.
So we only have one case left: restoring a live-snapshot. Here sadly
there seems no way out, it was possible to do with a "spice,usb3=1"
usb device, and thus all Snapshots taken on such VMs after they had a
clean restart on PVE 6 (to have a machine version >= 4.0) are broken
- but can be easily fixed by removing the "usb3=1" from the
problematic snapshot config.
As restoring a snapshot can be repeated more than once even on
failure without rendering the snapshot or VM permanently unusable,
this should be a reasonable compromise.
I strongly believe that the chance is so small that no one is
affected in practice and the property description mentioned that it
was not supported. If anybody is affected on snapshot restore we can
help them on a case-per-case basis.

the change to use a real diff to check tests, with it's nicer output
for failing cases, failed to ensure that the test system knew if a
case passed - earlier done indirectly by 'is_deeply', thus add a
manual 'pass' call if the tes was OK.
Further, the firs test failing aborted everything, which isn't to
nice, normally it's much more convenient if all test get run and one
can view at the results of all of them. So put the diff in an eval
and fail/note the test manually.
