5de6fd1ff8 mpegtspacketizer: Cache the GIConv

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.

76aedf5641 tsdemux: more correctly determine expected PES packet payload size 
... particularly considering that packet_length == 0 is possible.

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.

a996d2f01a Correct satellite delivery descriptor parsing. 
Original code to parse satellite delivery descriptors to generate
"satellite" structures appeared to be copy & pasted from cable's code
without amending for satellite.

Also added 8PSK to dvbsrc's enum for modulation.

b8f32811ca tsparse: Rework handling and cleanups 
tspad always has a static source pad which output everything received
(not functional yet).

Program pads are now request pads.

Remove all cruft that should have been removed from the switch over
to mpegtsbase.

5f7ecaa0f1 mpegtspacketizer: Reduce usage of GstAdapter 
Peek as much as possible in one go. Ideally we should remove usage of
adapter altogether, but for the time being it provides a big enough
speedup (around 2 times faster per packet processed).

b6732a27d3 pesparse: Be a bit more permissive with PTS/DTS parsing 
According to the specifications a PTS_DTS_flags value of 0x01 is forbidden.
... but there are some rare files out there that do that.

Instead of erroring out, let's warn, carry on parsing accordingly.

If the packet is really corrupted there are enough checks afterward to
detect that.

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

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.
