[Hans Petter Selasky]

Hi,

Can we agree on the following return values for callout_stop() and 
callout_reset() and their variants:

If the callout was scheduled regardless of being serviced or not,
.Dv CALLOUT_RET_CANCELLED
is returned.
If the callout was stopped and is still being serviced
.Dv CALLOUT_RET_DRAINING
is returned.
If the callout was stopped and is no longer being serviced
.Dv CALLOUT_RET_STOPPED
is returned.
