proxying the getcaps query to the downstream peer pad.

1b747bfecb h264parse: Fix splitting of multiple NALU per buffer
Conversion to byte-stream/nal crashes without that because the
baseparse frame of all NALUs is finished for the first NALU, then
used again for parsing the second NALU. Just that now the buffer
of the frame is already gone. Instead we create temporary frames
for every NALU.

7c23a6f23c mpegvparse: Fix last start code position when input buffer is empty
When the input buffer is empty and we need more data to determine
whether or not to terminate the previous frame, the last start code
location needs to be set to 4 bytes before the the current position
(size of start_code is 32-bits)

31d1c05871 h264parse: Add support for stream-format=avc3
When outputting in AVC3 stream format, the codec_data should not
contain any SPS or PPS, because they are embedded inside the stream.

In case of avc->bytestream h264parse will push the SPS and PPS from
codec_data downstream at the start of the stream, at intervals
controlled by "config-interval" and when there is a codec_data change.

In the case of avc3->bytstream h264parse detects that there is
already SPS/PPS in the stream and sets h264parse->push_codec to FALSE.
Therefore avc3->bytstream was already supported, except for the stream
type.

In the case of bystream->avc h264parse will generate codec_data caps
from the parsed SPS/PPS in the stream. However it does not remove these
SPS/PPS from the stream. bytestream->avc3 is the same as bytestream->avc
except that the codec_data must not have any SPS/PPS in it.

|--------------+-------------+-------------------|
|stream-format | SPS in-band | SPS in codec_data |
|--------------+-------------+-------------------|
| avc          | maybe       | always            |
|--------------+-------------+-------------------|
| avc3         | always      | never             |
|--------------+-------------+-------------------|

Amendment 2 of ISO/IEC 14496-15 (AVC file format) is defining a new
structure for fragmented MP4 called "avc3". The principal difference
between AVC1 and AVC3 is the location of the codec initialisation
data (e.g. SPS, PPS). In AVC1 this data is placed in the initial MOOV box
(moov.trak.mdia.minf.stbl.stsd.avc1) but in AVC3 this data goes in the
first sample of every fragment.

b17676a1d5 h264parse: Do not trigger caps update if we only have PPS updates
Updating caps results in downstream elements potentially reconfiguring themselves
(such as decoders). If we do this in the middle of keyframes, we would result
in those elements being reconfigured and handling garbage until the next keyframe.

Instead of this only send (potentially) new codec_data when we have *both* SPS and
PPS.

The caps should always represent what the user is supposed to see.
So if there is a sequence_display_extension associated with the
stream then use the display_horizontal_size/display_vertical_size
to update the src caps (if they are less than the values provided
by sequence header).

Also fixes issues when using playbin with decoder
sinks that want width/height etc.
