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`.

Prefer not casting at all to make sure we don't miss such an issue.

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.

950789f61b tsmux: tsmux_packet_out should always consume its buffer
Consuming the buffer only when successful is an antipattern and easily
leads to leaks.

55658ad166 tsmux: Don't memset in pad_stream when writing a PCR packet
tsmux_write_ts_header will write a stuffing adaptation field, so we
don't need to prefill the buffer.

2dbd89b036 tsmux: Move out parameters of tsmux_write_ts_header
Move them to the end of the parameter list and also allow passing NULLs
to ignore the payload information, but assert that the payload length is
zero in this case.

b1810d83bc tsmux: Fill padding packets with stuffing bytes
Instead of leaving it uncleared, emitting probably old packet data but
potentially also random or sensitive application data.

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.
