Makes ff_id3v2_read reset stream position at the end of ID3 data if the
header size is not matched (caused by an EOF for example).

Current behaviour (without the patch):
    filesize = 400
    id3 data size = 399
    file offset after ff_id3v2_read is 400 instead of 399

Correct the time interval between logged data rows to the expected
value of 100 milliseconds by naming a new loop counter variable
to be distinct from loop counters for inner loops that
inadvertently change the outer loop operation.

This suggested patch is 1 of 3 for Ticket #2144 "libavfilter ebur128
loudness inaccuracy, irregular time interval, LFE interference".
This suggested patch supersedes the contribution of January 15, 2013
in the thread “[PATCH] lavfi: EBU R.128 irreg time, ch weights, skip
LFE” which combined multiple fixes in one patch.

Previously VideoPicture->skip was used for that, using videoq.serial enables us
to detect obsolete frames right after pushing flush_pkt to the packet queue, so
we don't have to wait for the decoder thread to pop the flush packet anymore.

This is good because until now a full video picture queue may have blocked the
decoder thread.
