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.
