0a2e026985 mpegtsmux: detect and ignore gap buffers
Fixes #1291.  Without this, when a stream has gaps and then resumes, the next buffer PTS that is written to the TS is given the PTS of the first gap.

fecd38c8f6 tsmux: Ability for streams to disappear and reappear
Until now, any streams in tsmux had to be present when the element
started its first buffer. Now they can appear at any point during the
stream, or even disappear and reappear later using the same PID.

6892078b00 basetsmux: allow null J2K profile
Since we are not requiring that profile equals GST_JPEG2000_PARSE_PROFILE_BC_SINGLE,
(as the standard requires) we can allow profile to be null. We relax this condition because
OpenJPEG can't create broadcast profiles.

ef16d7558f mpegtsmux: Add SCTE-35 support
This adds two properties:
* scte-35-pid: If not 0, enables the SCTE-35 support for the current
  program. This will write the proper PMT and send SCTE-35 NULL
  commands (i.e. heartbeats) at a regular interval
* scte-35-null-interval: This specifies the interval at which the
  NULL commands should be sent

Sending SCTE-35 commands is done by creating the appropriate SCTE-35
GstMpegtsSection and then sending them on the muxer. See the
associated example

5464775aef tsmux: Disable bluray-isms from PMT
We were unconditionally adding top-level descriptors in the PMT which
were only related to bluray support for PS3 (from 10 years ago).

These should be re-added conditionally

73f92371b8 basetsmux: expose pcr-interval property
Instead of using a static hardcoded PCR interval, allow the user
to configure it.

Also revert back the default to a 40 ms interval, that was changed
in recent patches for no good reason.

76c3d98962 basetsmux: preserve user-specified sections across resets
As sections can be provided by the user through send_event
when the element state is NULL, their lifetime is expected
to match that of the muxer, and they must be preserved when
the state changes

91c76b0851 mpegtsmux: restore stream creation order
In 7c767f3fcd , stream creation was
refactored to occur before potential program creation. This created
issues with pipelines such as:

gst-launch-1.0 videotestsrc ! video/x-raw, format=I420, width=640, height=640, framerate=25/1 ! \
x264enc ! hlssink2 target-duration=1

eg.: gst_buffer_copy_into: assertion 'bufsize >= offset + size' failed

As this reordering was actually not needed for the purpose of allowing
to specify a PCR stream, this reverts the reordering part of the
initial commit.

14b9a34f54 mpegtsmux: add custom AC-3 descriptor
tsdemux expects a custom descriptor (GST_MTS_DESC_AC3_AUDIO_STREAM)
to detect a stream as AC3 and not EAC3.

Note that tsdemux expects this descriptor because mpegtsmux writes
a stream with a HDMV registration descriptor.

Fixes:

gst-launch-1.0 -v audiotestsrc ! avenc_ac3 ! ac3parse ! mpegtsmux ! \
tsdemux ! ac3parse ! avdec_ac3 ! audioconvert ! autoaudiosink
