Fix #1924: add snapshot parameter
The qm CLI command offer the config and showcmd functions. Both of those
outputs may vary with respect to a given snapshot. This adds a switch
that shows the corresponding snapshot's config and command line.
The code needs a newer libpve-guest-common-perl, thus bumping the
dependency.

migrate: fix local disk migration with online VMs
commit 4530494bf9f3d45c4a405c53ef3688e641f6bd8e introduced an
regression with local disk migrations if the VM is online and thus
needs to live migrated and no target storage was passed as parameter.
We made the hack to write "1" to the targetstorage option in this
case obsolete, but it was still used on deciding if there are any
drives to mirror at all. Here it is enough to check if there are any
'online_local_volumes' because that hash gets only filled if we can
and are told to live mirror local disk on migrations anyway. Also,
we abort early if local disks are found and the 'with-local-disks'
option is not set.

fix local disk migration when no target storage is set
the check for targetstorage in:
if ($self->{running} && $self->{opts}->{targetstorage} && $local_volumes->{$volid}->{ref} eq 'config') {
was obsolete, as we always set the tragetstorage opts variable to '1'
in a broader "use same sid for remote local" check above.
So removing it leads to the same if truthtable but fixes the
check if we should fallback to the volume's SID if targetstorage is
not set, as else it seemed to be always set, and '1' is naturally not
a correct stroage ID.

add win7 pcie quirk
Win7 is very picky about pcie assignments and fails with
'error 12' the way we add hospci devices.
To combat that, we simply give the hostpci device a normal port
instead.
Start with address 0x10, so that we have space before those devices,
and between them and the ones configured in pve-q35.cfg should we
need it in the future.

t/cfg2cmd: ensure tests can pass again
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.

fix check if machine type is q35
When live migrating, with a q35 machine will get the qemu version
encoded in the machine type, for example,'pc-q35-2.12', so we need to
allow this too and cannot expect that all q35 machine have
q35' in verbatim as their type.
So, when migrating such a machine live, we missed to include the q35

add qmeventd
this adds a program that can listen to qemu qmp events on a given socket
and if a shutdown event followed by a disconnected socket occurs,
executes qm cleanup with arguments that indicate if the
vm was closed gracefully and whether the guest initiated it
this is useful if we want to cleanup after the qemu process exited,
e.g. tap devices, vgpus, etc.
On arm we start off with a pcie bridge pcie.0. We need a
keyboard in addition to the tablet device, and we need to
connect both to an 'ehci' controller.
To do all this, we also pass the $arch variable through a
whole lot of function calls to ultimately also adapt the
hotplug code to take care of the new keyboard device.

Add `ssd` property to IDE, SATA, and SCSI drives
When enabled, the `ssd` property exposes drives as SSDs (rather than
rotational hard disks) by setting QEMU's `rotation_rate` property [1,
2] on `ide-hd`, `scsi-block`, and `scsi-hd` devices. This is required
to enable support for TRIM and SSD-specific optimizations in certain
guest operating systems that are limited to emulated controller types
(IDE, AHCI, and non-VirtIO SCSI).
This change also unifies the diverging IDE and SATA code paths in
QemuServer::print_drivedevice_full(), which suffered from:
* Code duplication: The only differences between IDE and SATA were in
bus-unit specification and maximum device counts.
* Inconsistent implementation: The IDE code used the new `ide-hd`
and `ide-cd` device types, whereas SATA still relied on the deprecated
`ide-drive` [3, 4] (which doesn't support `rotation_rate`).
* Different feature sets: The IDE code exposed a `model` property that
the SATA code didn't, even though QEMU supports it for both.
Instead of our own. The code is almost the same, but the
upstream implementation uses qemu's transactional system and
performs a drain() on the block device first. This seems to
help avoid some issues we run into with qcow2 files when
creating snapshots.

this adds a VM Generation ID device uses by Windows (Server) to determine
some specific actions that may have happened with the vm
such as rollback, restore, etc.
the OVF tests use `qemu-img`, which is provided by either our
pve-qemu(-kvm) or qemu-utils (upstream).
Use qemu-utils as it's provided by ours and upstreams package and
thus makes bootstrapping easier, e.g., if our qemu package is not yet
installed this can still be build.
