838c5f3df7 avformat/utils: Redesign scoring in av_find_default_stream_index() 
This avoids empty streams from being selected if a equivalent non empty one is available
The new system is also clearer and more systematic
This may need finetuning, which should be easy to do ...

Fixes Ticket2687

6c7f1155bb avformat/mp3dec: avoid early EOF with concatenated gapless mp3s 
Consider a file created with something like:

    cat file1.mp3 file2.mp3 > result.mp3

Then if file2.mp3 has gapless information, result.mp3 would stop playing
something in the middle. This happens because the gapless info directs
the decoder to discard all samples after a certain position. To make
matters worse, the gapless info of file2.mp3 will be used when playing
the file1.mp3 part, because the gapless info is located at the end of
the file.

While handling concatenated gapless files correctly would be insane and
a lot of effort (especially without scanning the whole file on opening),
it's easy to prevent at least early EOF. Playback will happen to work,
even if it's slightly broken.

d87fe2687f avformat/mp3dec: fix gapless audio support 
The code already had skipping of initial padding, but discarding
trailing frame padding was missing.

This is somewhat questionable, because it will make the decoder discard
any data after the declared file size in the LAME header. But note that
skipping full frames at the end of the stream is required. Encoders
actually create such files.

d92550d191 lavf: eliminate ff_get_audio_frame_size() 
It is basically a wrapper around av_get_audio_frame_duration(), with a
fallback to AVCodecContext.frame_size. However, that field is set only
when the stream codec context is actually used for encoding or decoding,
which is discouraged.

For muxing, it is generally the responsibility of the caller to set the
packet duration.
For demuxing, if the duration is not stored at the container level, it
should be set by the parser.

Therefore, removing the frame_size fallback should not break any
important case.
