afs: Add metadata xattrs
Add xattrs to allow the user to get/set metadata in lieu of having pioctl()
available. The following xattrs are now available:
- "afs.cell"
The name of the cell in which the vnode's volume resides.
- "afs.fid"
The volume ID, vnode ID and vnode uniquifier of the file as three hex
numbers separated by colons.
- "afs.volume"
The name of the volume in which the vnode resides.
For example:
# getfattr -d -m ".*" /mnt/scratch
getfattr: Removing leading '/' from absolute path names
# file: mnt/scratch
afs.cell="mycell.myorg.org"
afs.fid="10000b:1:1"
afs.volume="scratch"
