REVIEW: https://review.gluster.org/21068 (server-protocol: don't allow '../'
path in 'name') posted (#1) for review on master by Amar Tumballi

COMMIT: https://review.gluster.org/21068 committed in master by "Amar Tumballi"
<amarts at redhat.com> with a commit message- server-protocol: don't allow '../'
path in 'name'

This will prevent any arbitrary file creation through glusterfs
by modifying the client bits.

Also check for the similar flaw inside posix too, so we prevent any
changes in layers in-between.

Fixes: bz#1625095
