Moved the user and group functions to libxcpu.
libxcpu now provides an API to add/delete/flush users.
for xuserset and xgroupset, it's just a matter of calling these
functions now.
the main motivation for this patch is that schedulers need to call these
functions to add/delete users from the group pool when they submit a
job.
