Up to [Development] / xfs-cmds / xfsdump / restore

Another approach to restoring the immutable flag at the correct
time. Also addresses some inefficiencies in restoring metadata
on files dumped in multiple extent groups and files with
extended attributes.
Back out changes that required the dirattr routines to be used for
restoring the immutable flag on regular files which had extended
attributes.
