6622e2dacf mpegtsdemux: Implement efficient program updates

bcc06d679a mpegtsdemux: Switch to using GstStream/GstStreamCollection
For each MpegTSBaseStream, we have a GstStream object which
subclasses can extend with information.

For each program a GstStreamCollection is created with all
GstStream from each stream.

14e6d2d427 mpegtsdemux: Allow deactivation of programs to be delayed
When changing programs, the order of events needs to be the following:
* add pads from new program
* send EOS on old pads
* remove old pads
* emit 'no-more-pads'

Previously tsdemux was not doing that, and was first deactivating and
removing old pads before adding new ones.

We fix this by allowing subclasses of mpegtsbase to be able to handle
themselves the deactivation of programs. In this case tsdemux will
properly deactivate it once it has activated the new program.

a49ce685d1 tsparse: Implement timestamp/retimestamping of output buffers
When the set-timestamps property is set, use PCRs on the provided
(or autodetected) pcr-pid to apply (or replace) timestamps on the
output buffers, using piece-wise linear interpolation.

This allows tsparse to be used to stream an arbitrary mpeg-ts file,
or to smooth jittery reception timestamps from a network stream.

The reported latency is increased to match the smoothing latency if
necessary.

22dfd9aef3 mpegts: Unify API : GstMpegts / gst_mpegts_ / GST_*_MPEGTS_
It was previously a mix and match of both variants, introducing just too much
confusion.

The prefix are from now on:
* GstMpegts for structures and type names (and not GstMpegTs)
* gst_mpegts_ for functions (and not gst_mpeg_ts_)
* GST_MPEGTS_ for enums/flags (and not GST_MPEG_TS_)
* GST_TYPE_MPEGTS_ for types (and not GST_TYPE_MPEG_TS_)

The rationale for chosing that is:
* the namespace is shorter/direct (it's mpegts, not mpeg_ts nor mpeg-ts)
* the namespace is one word under Gst
* it's shorter (yah)

* Avoids handling twice the same seek (can happen with playbin and files
  with subtitles)
* Set the sequence number of the segment event to the sequence number of
  the seek event that generated it (-1 for the initial one).

1c96c79b88 mpegtsdemux: Handle private section streams
Until now we simply ignored those streams (since we couldn't do anything
with it anyway). Now that we have the mpegts library and we offload the
section handling to the application side we can properly identify and
extract them.

By default it is disabled for tsparse and enabled for tsdemux, but there is
a property to change that.

This should open the way to properly handle all private section streams,
including:
* DSM-CC
* MHEG
* Carousel data
* Metadata streams (though I haven't seen any of those in the wild)
* ... And all other specs/protocols making use of those

Partially fixes #560631

80dd130fb0 Revert "tsbase: add a guard with an atomic boolean when flushing"
This reverts commit e14e310f71.

Would be better move the packetizer flushing to FLUSH_STOP and avoid
the race that way. Without introducing a memory barrier that could
have impact in the performance.

558beab1b4 mpegtbase: vmethod to notify when we're done processing input
This can be used to notify subclasses no more data is expected this
round.
tsparse will use it to push whole buffers (without copy) on the main
source pad.
It could also be used later to decide whether to push pending data
in order to reduce latency.
