And remove the function altogether while at it. It's a duplicate of
another.

This effectively copies the side data elements from src instead of
potentially merging them with those already existing in dst.
This by extension also removes the only dependency on existing values
in the dst packet.

Right now, the PTS always starts out as 0, which causes problems on a
seek or when inserting this filter mid-stream.

Initialize it instead to AV_NOPTS_VALUE and copy the PTS from the first
frame instead if this is the case.

When ff_h264_decode_mb_cavlc() failed due to wrong sl->qscale values,
e.g. dquant out of range, set the qscale to be a valid value before
returning -1 and exiting the function. The qscale value can be used
later e.g. in loop filter.

These were needed for ABI compatibility with Libav. We don't need them
anymore.

This changes how NTSC VANC is extracted from the buffer. In NTSC the vanc data
is interleaved between luma and chroma, and not just the luma as in high
definition resolutions.

In my testing this allows a decklink card encoding valid NTSC closed
captions to pass the caption data to the x264 encoder.

Updated with reviews from Devin Heitmueller and Marton Balint.

In a recent commit the default was changed from 0 (component) to 5
(unspecified), however some standards require using 0. With this option, the
user will be able to do so.

Fixes an assertion failure:
Assertion size >= 2 failed at libavformat/matroskaenc.c:298

A basic test for demuxing raw AAC (ADTS) with ID3v2 tags.

While rare, ID3 tags may be inserted between ADTS frames. This change enables
parsing them and setting the appropriate metadata updated event flag.

Fixes compilation of libavformat when librtmp is enabled but all the
relevant protocols are disabled.
