We now use 'pixelformat' for V4L2_PIX_FMT_* (as they do in v4l2
documentation) and 'pix_fmt' for AVPixelFormat.

No functional change in the code.

It is not supposed to be set by demuxers.

The reasoning is the same as for
0097cbea.

The only parameters needed by the demuxers are the sample rate and sample
count, which can be trivially extracted manually, without resorting to
an avpriv function.

It will not be set unless the codec context is used as the encoding
context, which is discouraged. For MP2, av_get_audio_frame_duration()
will already set the frame size properly. For MP3, set the frame size
explicitly.
