4ca886c53b mpegtsbase: Call ::program_stopped after removing all streams 
Subclasses want to access the program while removing the streams
and will currently crash because of dereferencing NULL in some cases.

cc40d49bed mpegtsbase: flush in FLUSH_STOP to avoid race conditions 
Ensure the chain is not running before reset the state to avoid race
conditions and random corruptions downstream.
Also fixes segfaults in the packetizer due wrong available values that
causes gst_adapter_map to return a NULL pointer.

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.

651203de07 mpegts: Only use timestamp-based PCR/PTS estimation when needed 
When dealing with non-time based push-mode streams, we need to revert
to using the offset-based PCR/PTS estimation logic of packetizer.

This solves uses cases such as:
 pushfile:// ! tsdemux
 src ! queue ! tsdemux

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.

8cb0e87f56 mpegtsdemux: Not apply various time the same PMT to a program when repetead 
Sometimes their are several times the same PMT applying to a same program in a stream,
tsdemux was totally baffled when this was happening, we now keep the one we
already applied so it works properly.
