This reverts commit f792c78c96.
With the "Use range_streamer everywhere" (7217b7ab36) series,
all the user of streaming now do streaming with relative small ranges
and can retry streaming at higher level.
Reduce the time-to-recover from 5 hours to 10 minutes per stream session.
Even if the 10 minutes idle detection might cause higher false positive,
it is fine, since we can retry the "small" stream session anyway. In the
long term, we should replace the whole idle detection logic with
whenever the stream initiator goes away, the stream slave goes away.
