43938bbf54 tsdemux: Fix name of CAT GstStructure

10c881b107 tsdemux: fix some inconsequential PES header parsing issues 
additional_copy_info: need to get rid of the highest
bit, not the lowest one

program_packet_sequence_counter: also need to get rid
of the highest bit instead of multiplying with a random
value

original_stuff_length: want to AND 0x3f to extract the
lowest 6 bits, not multiply by it.

None of these fields are actually used though, so these
should not have caused any issues.

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.

006fe188e7 tsdemux: correctly determine expected PES packet payload size 
Avoids consistently failing to detect that a packet is complete, which
would then only be pushed upon the start of a next packet, which leads
to quite a delay in case of a sparse (subtitle) stream.

b6732a27d3 pesparse: Be a bit more permissive with PTS/DTS parsing

detect that.

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.

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.
