ca234639ac avidec: avoid infinite loop due to negative ast->sample_size 
If max in clean_index is set to a negative ast->sample_size, the
following loop never ends:
        while (max < 1024)
            max += max;

Thus set ast->sample_size to 0 if it would otherwise be negative.

0eec40b713 avidec: check for valid bit_rate range 
If bit_rate is negative, it can trigger an av_assert2 in av_rescale_rnd.

Since av_rescale returns int64_t, but st->codec_bit_rate is int, it can
also overflow into a negative value.

90411b333d Allow reading of growing avi files (currently being written) 
This uses the RIFF header stored size to figure out the expected AVI
file size, instead of the actual file. To work fully it requires handling
failed avio_seek() instead of assuming they always succeed.

Some fate file has been cut off and contains half a frame at the end which
previously was not output during demuxing. This frame is now output to
encoder, thus the fate diff update.
