7c6093357b videoparsers: Fix GstBaseParse::get_sink_caps() implementations 
They should take the filter caps into account and always return
the template caps appended to the actual caps. Otherwise the
parsers stop to accept unparsed streams where upstream does not
know about width, height, etc.

Fixes bug #677401.

9f7e70f754 mpegtbase: ECM/CA sections don't have a CRC 
So don't check for it :)

Also add a bit more info in the warning message to speed up detecting
whether it's a false-positive or not.

7784c0d350 mpegtsbase: Check before getting descriptors from structure 
Avoids spurious warnings. Not having those descriptors is nothing
fatal, so check their presence before trying to get them.

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.

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.

35a58df012 mpegvideoparse: Revert "fix crash" 
This reverts commit 91210831ee672343a296f31357144359d5c2e768.

Such explicit reset should not be needed as it is arranged for by
the baseclass in unison with monitoring for a new frame by subclass.

As such it might wrongfully hide something else going on ...

See #674073.

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.
