afs: Get YFS ACLs and information through xattrs
The YFS/AuriStor variant of AFS provides more capable ACLs and provides
per-volume ACLs and per-file ACLs as well as per-directory ACLs. It also
provides some extra information that can be retrieved through four ACLs:
(1) afs.yfs.acl
The YFS file ACL (not the same format as afs.acl).
(2) afs.yfs.vol_acl
The YFS volume ACL.
(3) afs.yfs.acl_inherited
"1" if a file's ACL is inherited from its parent directory, "0"
otherwise.
(4) afs.yfs.acl_num_cleaned
The number of of ACEs removed from the ACL by the server because the
PT entries were removed from the PTS database (ie. the subject is no
longer known).
