avformat/mp3: large id3 tags break concatenated file detection If the file size is much larger than what is indicated in the XING header, the demuxer assumes it's a concatenated file, and throws away the (presumably) incorrect duration information. Unfortunately, this also triggers if the id3 tags are very large (embedded pictures and such). Then the half-baked heuristic not only breaks the duration display, but also gapless audio. Fix it by subtracting the size of the headers (the check is off by some bytes, but that doesn't matter at all). Note that there could be an arbitrary amount of tags _after_ the mp3 data, but hopefully these are not too large to trigger the heuristic in practice. Also add a warning when this happens.
