The new expansion mechanism uses the %{...} notation.
For compatibility reasons, it must be enabled explicitly,
but a warning is printed if a conflict is likely to happen.

I guess the user expects to see the stream with the highest bitrate, not with
the most frames, this is especially useful for multi bitrate streams.

This patch changes av_find_best_stream to select the stream based on a number
of conditions, the first condition has the highest priority, the last condition
has the lowest:

1) Select the stream with the highest FFMIN(5, codec_info_nb_frames) value
2) Select the stream with the highest bitrate
3) Select the stream with the highest codec_info_nb_frames
4) Select the first stream

Fixes crashes on Win32 and stack overruns on x86-32 in general.

If there are any samples remaining in the output fifo from previous conversion
calls, we have to output those samples first instead of doing direct output
of the current samples.
