c3a161f287 basetsmux: rework SCTE section handling to handle passthrough
mpegtsmux can receive SCTE sections from two origins: events
created by the application, and events forwarded downstream by
mpegtsdemux, containing sections that may not have been fully
parsed, and additional data to help tsmux translate times to
the correct domain, both for requesting keyframes and calculating
an accurate pts_adjustment.

The complete approach is documented further in a comment above
the relevant function.

e4f40ba526 mpegtspacketizer: handle "packetizing" already packetized data
.. when the section didn't have a packetizer. This can happen
as a result of building a new section from a copy of the original
data of another section.

61fecce193 gst-scte-section: implement partial parsing
In cases where either the SIT is encrypted, or an unknown
command is encountered, we still want to send an event downstream.

d17c7f25e6 scte35-section: semantic API break
Document that the constructors for the splice events expect
a running time, as users of the API can not be expected to
predict the appropriate local PTS.

a9787d0c85 scte-section: add support for packetizing time_signal splices
time_signal splices are trivial, they only contain a splice_time()
and all the relevant information is carried in descriptors.

a03c395582 mpegtssection: expose event constructor
This allows the demuxer to forward sections of interest downstream,
for example SCTE 35 splice information. These can then be reinjected
appropriately by a muxer for example.
