core, client, server: Support auxiliary group ids
Support for auxiliary group ids is needed for transmission of more than one group id right through the xlator tree so that posix can use these group ids to perform in-house permission tests. The in-house permission checks are needed so that we do not have to depend on non-POSIX calls like setfs[ug]id for changing the user for each fop. The setfs[ug]id are also limited since they do not allow setting multiple group id as required for operation with NFS, which sends us all the group ids for a process issuing file system requests.

Avati <avati@dev.gluster.com> BUG: 400 (Support auxiliary gids in GlusterFS) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=400
