With this property, one can enable compression for individual files
without the need to mount the filesystem with the compress or
compress-force options, and specify the compression algorithm.
When applied against a directory, files created under that directory
will inherit the compression property.
This requires the corresponding kernel patch, which adds the support
for setting and getting properties and implements the compression
property.

So that we can get the label of a mounted filesystem.
Before this change:
$ btrfs prop get /mnt/btrfs label
ERROR: object is not compatible with property
$ btrfs prop get /dev/sdb3 label
ERROR: dev /dev/sdb3 is mounted, use mount point
ERROR: failed to set/get property for object.
After this change:
$ btrfs prop get /mnt/btrfs label
label=foobar

"btrfs filesystem property" is a generic interface to set/get
properties on filesystem objects (inodes/subvolumes/filesystems
/devs).
This patch adds the generic framework for properties and also
implements two properties. The first is the read-only property
for subvolumes and the second is the label property for devices.
