storage/posix: Add virtual xattr to fetch path from gfid
The gfid2path infra stores the "pargfid/bname" as on xattr
value for each non directory entry. Hardlinks would have a
separate xattr. This xattr key is internal and is not
exposed to applications. A virtual xattr is exposed for
the applications to fetch the path from gfid.
Internal xattr:
trusted.gfid2path.<xxhash>
Virtual xattr:
glusterfs.gfidtopath
getfattr -h -n glusterfs.gfidtopath /<aux-mnt>/.gfid/<gfid>
If there are hardlinks, it returns all the paths separated
by ':'.
A volume set option is introduced to change the delimiter
to required string of max length 7.
gluster vol set gfid2path-separator ":::"
