fuse: flip xattr key from user to trusted namespace for certain
clients.
This is needed for gsyncd/hadoop-plugin running as non-super
user to be able to request extended attributes under trusted
namespace. Request for a key is made under 'user.' namespace
and is flipped by fuse xlator for specific xattr name to the
corresponding 'trusted.' extended attribute.
Both applications set a identifier (client-pid) while doing a
FUSE mount, which is checked by get/set/remove interfaces in
FUSE translator.
