When converting to virObject, the probes on the 'Free' functions were removed on the basis that there is a probe on virObjectFree that suffices. This puts a burden on people writing probe scripts to identify which object is being dispose. This adds back probes in the 'Dispose' functions and updates the rpc monitor systemtap example to use them Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
