cleanup and fix xattr namespace flip
- function of actual flipping made static - clean out references to particular namespaces from flipping logic - namespaces involved in flipping defined at single location - fix fnmatch(3) invocation with reversed pattern and string arguments - instead of "user", use "system" to flip from, because latter is free from supervision of the VFS layer (cf. attr(5)) Change-Id: I3cc5836fadcad5b237fd5c67d0dcaea63aee9164 BUG: 798716 Signed-off-by: Csaba Henk <csaba@redhat.com> Reviewed-on: http://review.gluster.com/2890 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Venky Shankar <vshankar@redhat.com>
