The purpose of the serial field is to accompany the decoded data during the
decoding process to know if the decoded data belongs to the data stream after
the latest packet queue flush.

We now initalize the external clock to 0 and, we use the system clock to
regulate the timings of audio and video in external clock sync mode.  We
recover from external clock sync loss, when the delay to external clock is
bigger than AV_NOSYNC_THRESHOLD.

This makes sensible audio and video clock values even before displaying the
first frame.

When using external sync, framedrop is perfectly fine.

This is not based on lucas work due to code divergence (its less work this way
than trying to merge from a split based on 2 years outdated code)

The libav code depends on mp3 startcodes only occuring at the start of
frames. But there is nothing in mp3 that prevents them occuring elsewhere
by chance. Thus the code would fail randomly, the new code searches for 3
consecutive valid frames. If this turns out to be still insufficient the
number can be raised further, or additional checks added.
