6bf54ff850 tsdemux: Adapt to new packetizer API
We no longer use GstBufferList and instead copy the incoming data
into newly allocated memory.

This makes tsdemux behaviour 3 to 4 times faster.

5536bcf8b8 tsdemux: flush on pusi only for payload packets
Data should not be flushed out of the tsdemux because a payload unit start
indicator (pusi) is seen in a adaptation only ts packet. If the package contains no
payload a pusi does not indicate a new PES packet, but PSI information, etc.
This fixes playback of several TS files which contain ts packets without
payload but with pusi set to 1.

e75612c3fd tsdemux: Don't queue data for streams that don't have a pad
This would result in an error further down, and it also avoids processing
for that data which we wouldn't be using anyway.

We need to reset the stream on a flush or else old packets could be added to the

c557f71756 tsdemux: Push packets as early as possible
When the PES header tells us how big the outgoing packet is, push the
packet downstream as soon as we have the specified size instead of waiting
for the beginning of the next packet.
Reduces latency and removes issues with very sparse streams (like subtitles
and subpictures).

818762e8fc tsdemux: do not send a new-segment on stream removal
When a program is changed, stream_added is called which sets the
need_newsegment to TRUE, then stream_removed is called, which calls
the flush_pending_data, which checks for the newsegment and causes
it to send a new-segment.

We must not send the newsegment when flushing the pending data on the
removed stream. We should only push it when flushing data on the newly
added streams (after they finish parsing their PTS header)

and the current PTS of the stream

57279cdd24 tsdemux: Refactor stream/program removal
The program_stopped vmethod was called before stream_removed vmethod
was being called. Since we only did stream-related operations in there,
we just remove the program_stopped vmethod and do everything in the
stream_removed one.

Also, make sure we flush out all pending data before sending EOS.
