libceph: eliminate sparse warnings
Eliminate most of the problems in the libceph code that cause sparse to issue warnings. - Convert functions that are never referenced externally to have static scope. - Pass NULL rather than 0 for a pointer argument in one spot in ceph_monc_delete_snapid() This partially resolves: http://tracker.ceph.com/issues/4184 Reported-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Alex Elder <elder@inktank.com> Reviewed-by: Josh Durgin <josh.durgin@inktank.com>
