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.
