4af003bc02 tsdemux: switch SCTE 35 sections handling to a passthrough model
Instead of modifying the splice times in the incoming sections
to running time and expecting eg mpegtsmux to convert those back
to its local PES time domain, which might be impossible when
those splice times are encrypted or the specification is extended,
transmit the needed information to the muxer as separate fields in
the event:

* A pts offset field can be used by the muxer in order to calculate
  a final pts_adjustment

* A rtime_map can be used by the muxer to determine the correct
  running times at which it should request keyframes

be4d0fff23 basetsmux: extend SCTE 35 support
Makes it possible to support passing SCTE 35 cue points from
demuxer to muxer, while preserving correct timing.

This will also improve ex nihilo cue points injection, as splice
times and durations are now interpreted as running time values,
and may trigger key unit requests.

1ca08bff57 tsdemux: Expose send-scte35-events property
When enabled, SCTE 35 sections (eg ad placement opportunities)
are forwarded as events donwstream.
