It may happen when stream is being copied.
This commit allows to store such stream and provides
backward compatibility with version prior 2.5 release.

If src_len is too small for nal_size, we already print a warning
above, and the next step is to check the while loop condition
anyway, so this one serves no purpose.

Previously, errors were only logged but the code kept on trying,
and never actually returning the error as a return value.

Including libavcodec/get_bits.h is superfluous for AV_RB16 - nothing
in this file uses any actual bitstream reader.

This allows the output to be used with stream copy, which discards
packet from the start until the first keyframe.

Outputting DNxHD into .mov containers 'corrupts' following atoms until end of stsd

ffmpeg and qtdump could not decode pasp/colr atoms in the files made by ffmpeg,
when outputting DNxHD due to the incorrect padding placement. Now we add the
padding in the correct place

Tidy up FATE changes due to padding changes.
