The usage() in help.c calls exit(1), so the break behind is nonsense
and should be removed.

Several fixes:
1) The function check_is_root() returns 0 if the object is root;
2) Don't treat any error from get fsid ioctl as meaning the target
is root. Only -ENOTTY means it's a root (parent directory is
not a btrfs fs) and a -ENOTDIR means our target object is not a
directory, therefore it can be the root;
3) Fix the comparison of the target and target's parent fs ids. If
they are different, it means the target is a mount point in a
btrfs fs, therefore it's a root, otherwise it isn't.

"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.
