Volume with save_on_stop=False and snap_on_start=False exists only when
VM is running and this is already handled under is_dirty() condition.
For non-running VMs, skip LVM resize step and only update internal size
attribute.
FixesQubesOS/qubes-issues#5645
When volume is resized, underlying LVM is adjusted if exists. For
persistent volumes it is enough, as generally the driver prefers
underlying LVM size than internal attribute. But volatile volume is
removed at vm shutdown, so that value is lost.
Fix it by updating Volume.size attribute too, to be updated in qubes.xml
later too.

storage/reflink: trivial style tweaks
storage/reflink: comment on _get_size() use in start()
storage/reflink: don't bother using _get_size() in create()
storage/reflink: delete all images at beginning of create()
storage/reflink: get VM dir from less arbitrary-looking path

storage/reflink: _remove_incomplete_{files -> images}()
storage/reflink: omit redundant comment
Ensure that there are no leftover image files for the volume, e.g. from
an unsuccessful removal of a previous incarnation of this vid, or from
an messily restored pool filesystem backup. We don't want to preserve
any stale data (revisions) or metadata (size) in the new incarnation.
The size config parameter might be a string coming from XML.
The Volume base class handles the conversion to integer already.
FixesQubesOS/qubes-issues#5219.
This should allow importing a volume and changing the size at the
same time, without performing the resize operation on original
volume first.
The internal API has been renamed to internal.vm.volume.ImportBegin
to avoid confusion, and for symmetry with ImportEnd.
See QubesOS/qubes-issues#5239.
* origin/pr/310:
storage/reflink: fix comment
storage/reflink: bail out early on most FICLONE errnos
storage/reflink: pool.setup_check -> pool._setup_check
Don't fall back on 'cp' if the FICLONE ioctl gives an errno that's not
plausibly reflink specific, because in such a case any fallback could
theoretically mask real but intermittent system/storage errors.
Looking through ioctl_ficlone(2) and the kernel source, it should be
sufficient to do the fallback only on EBADF/EINVAL/EOPNOTSUPP/EXDEV.
(EISDIR/ETXTBSY don't apply to this storage driver, which will never
legitimately attempt to reflink a directory or an active - in the
storage domain - swap file.)

Update tests after adding /connected-ips
Also reload /connected-ips on firewall change / domain spawn
Also store /connected-ips6 for machines that have IPv6 addresses
Don't try to write to qubesdb of an offline VM
Maintain a list of connected machine IPs in qubesdb
