For a 'raw' volume, the path includes the '/disk.raw' suffix, but the
check expects the containing subvolume directory.

Hard-coding a list of sensitive properties means that custom plugins
cannot define their own sensitive properties for the on_add/on_update
hooks.
Have plugins declare the list of their sensitive properties in the
plugin data. For backwards compatibility, return the previously
hard-coded list if no such declaration is present.

The helper iterates with the BTRFS_SNAPSHOT_REGEX regular expression,
so there will always be a snapshot name.

It was originally introduced as $snapshot to match the argument name of
foreach_subvol, we rename it here to make it clear that it only contains
the snapshot name.

When a subvolume is transferred via btrfs send/receive the resulting
image contains the received_uuid property set. This property is required
to do incremental snapshots.
A downside though is that once the received_uuid property is set, it is
not possible to make the image readwrite again without the force (-f)
flag, and in such case the received_uuid property is lost. Since we know
the images are only set to rw for the duration of the move, it is safe
to set the flag forcefully and then in a future commit add the
received_uuid property by force.

Replaces the current use without changes. The `$dir` variable is not
used anymore at that moment so it is defined later.

Suppose we are taking a snapshot of VM 100's disk-0. The
dir_glob_foreach runs over $path=/subvolume/images/100, lists all
snapshot names and appends their names to the path of the disk, e.g.
/subvolume/images/vm-100-disk-0@SNAP_NAME, but the original directory
$path might contain a second disk `vm-100-disk-1` which is also listed
by the dir_glib_foreach.
By using the helper we only iterate over the snapshots of the guest.

In this context a subvolume means a BTRFS subvolume.
`$volume\@$snap_name` would be for example
`btrfs_volume/images/102/vm-102-disk-0@snap_name`.

The only (transitive) caller that seems to be interested in the format
is the API endpoint for content listing.
The warning about not being able to query in the expected format might
not be seen by consumers that only use the API result, so this helps
admins detect such images. It is also for future-proofing, should any
new callers want to use only images of certain formats to error out
early.

This avoids auto-detection by qemu-img and so the information will be
correct with respect to the actual image format on the storage layer.
Should the image not be in the correct format, warn and try again
querying as raw, so the image is still listed. The image is present,
so it is better if it is listed and for some backwards compatibility.
The format is still returned as the matched format in such a case,
because that is how the image is treated, even if corrupt.

Adds the ability to change the owner of a guest image.
Btrfs does not need special commands to rename a subvolume and this can
be achieved the same as in Storage/plugin.pm's rename_volume taking
special care of how the directory structure used by Btrfs.

If we want to forward to the create_base of the directory plugin while
making that use our $class for the operations that call might do, we
cannot use the -> notation (which would resolve the next actual
implementation) but rather pass the class directly.
But, DirPlugin reuses the create_base method from the base Plugin
method, so we also need to call that, because on direct call notation
the inheritance fallback to super methods isn't available.

The `mkdir` option has two meanings[0][1] which are split up in `create-path`
and `create-sub-dirs`.
The `create-base-path` option decides if the path to the storage is
automatically created or not.
The `create-subdirs` options decides if the default directory
structure (dump, images, ...) at the storage location is created.
The `mkdir` option is still working but will trigger a warning in the
logs.
As a side effect, this also fixes#3214 because the `create-base-path` option
is now run after the `is_mountpoint` check in the `activate_storage`
method in DirPlugin.pm.
The 'mkpath' command has been moved into a new helper function that
first determines if the conditions to create the path is true, called
'config_aware_base_mkdir'.
