b405ff34d3 mpegtsmux: allow attaching PCR to non-PES streams 
There is an existing PMT mapping between PCR_%s and an mpegtsmux sink
pad name, where %s equals the program number that the PCR corresponds
to. We re-purpose this functionality to also support a mapping between
PCR_%s and an arbitrary PID. If this mapping is set, then the header PCR
PID is set to this value, and PCR is attached to the stream with this
PID.

Note: the current implementation also attaches PCR to the video stream,
so this may be inefficient.

6053dd0d1b tsmux: Fix default get_es_descrs_func 
`tsmux_stream_default_get_es_descrs` is missing the `user_data`
parameter and shouldn't be cast to `TsMuxStreamGetESDescriptorsFunc`.

db88612853 tsmux: Simplify tsmux_section_write_packet 
- Don't try to make the parameters match `GHFunc`. Use a dedicated
  callback for `g_hash_table_foreach`.
- Don't try to be clever with buffer memories. We're allocating a full
  packet anyway, might as well memcpy and save on a lot of complexity.

a72ca72a27 mpegtsmux: add stream-number property on GstBaseTsMuxPad 
This new property allows setting of PES stream number for AAC audio
and AVC video streams.

The stream number is subject to the following constraints:

1. it must be between 0 and 15 for video
2. it must be between 0 and 31 for audio

Currently the PES stream number is hard-coded to zero for these
stream types.

52c419b799 mpegtsmux: Disable aggregator's default negotiation 
mpegtsmux can't negotiate caps with upstream/downstream and always outputs
specific caps based on the input streams. This will always happen before
it produces the first buffers.

By having the default aggregator negotiation enabled the same caps
would be pushed twice in the beginning, and again every time a
reconfigure event is received.

95ff949eff mpegtsmux: Start last_ts with GST_CLOCK_TIME_NONE 
And use the output segment position for the outgoing timestamp while it
is. This is needed to delay the calculation of `output_ts_offset` until
we actually have a usable timestamp, as tsmux will output a few initial
packets while `last_ts` is still unset.

Without this, the calculation would use the initial `0` value, which did
not have the intended effect of making VBR mode behave like CBR mode,
but always calculated an offset equal to the selected start time.

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.
