a0a184931a tsdemux: Add language code to taglist.

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.

c6035d403c mpegtspacketizer: Avoid usage of GstBuffer internally 
The overhead of creating/using 188 byte GstBuffer from GstAdapter
is too expensive.
We now peek the next packet, and provide a data/size which is only
valid until the packetizerpacket is cleared.

In addition, cleanup all the internal code to deal with that new
behaviour and remove double-checks which are no longer needed.

The section_length is now the corrected section_length (i.e. with
the additional 3 bytes).

Avoid using gst_adapter_prev_timestamp and instead track
the timestamp ourself.

6d01f5f1b3 mpegtspacketizer: Detect PCR wraparound in skew code

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.

c557f71756 tsdemux: Push packets as early as possible

packet downstream as soon as we have the specified size instead of waiting
for the beginning of the next packet.

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)

cbc0a2f056 mpegtsbase: Prevent stack gardening by using the right type 
stream_type is stored as guint inside the GstStructure but was retreived
using valist with a pointer to guint16. This would cause stack gardening
when code is compiled without optimisation (e.g. in -O0 the compiler wont
pad the stack to optimise out required mask).
