The table is automatically generated from the definition of enum CodecID in
avcodec.h and contains the name of all known codecs, even those for which no
encoder nor decoder exists or is enabled.

The table is queried using the avcodec_get_name function.

If CONFIG_SMALL is true, the table is not compiled in; the avcodec_get_name
looks for names in the list of available decoders and encoders.

This is required for the pending lavfi indev extension, also
consistent with the video buffer sink.

Allow factorization for the pending work on the audio movie source.

libmp3lame if available, ac3 otherwise.

libvorbis/libx264 for video if available, otherwise ac3/mpeg4.

Clarify with an example what the user should use instead of the
deprecated (and no longer working) -s/-pix_fmt options.

Getting rid of globals are generally a good thing. The patch also makes
toggle_pause and step_to_next_frame use a function parameter instead of
the global cur_stream variable.

Add the sar option. Useful for debugging/testing purposes.

This fixes the situation when there are not enough entries in the index
(e.g. on initial seek there's only one index entry in the index) and index
search returns just the last known entry. That causes seeking function just to
seek there instead of trying harder to get at the requested position.

Currently for multichannel audio position for the last block position is
stored in index (and used for seeking), which is obviously not correct.
