livesync: Fix #452

• livesync: Split fallback_duration into in_ and out_duration
  Make it independent of the latency; this was inconsistent anyway, where the default latency of zero got you a fallback duration of 100 ms and something else got you half the latency.

  Maintain a separate duration for the in and the out side so we change the duration of repeat buffers after a caps change, not just before.

• livesync: Keep existing buffer duration in some cases
  Resize a repeat buffer only if caps gave us a duration to use, or we consider its current duration unreasonable.

  In particular, for audio streams we should prefer reusing the buffer size upstream gave us, as we did before 6633cc40.

• livesync: Remove the stop from outgoing segments
  Our buffer duplication can extend a segment indefinitely.
