everybody else around ;-)

Roman Shaposhnik 380fd6b1b4 * DV decoder simplifications. Now it looks to be 6% faster. At least
on my desktop.

Roman Shaposhnik e15c330246 * 3x encoding speedup. Finally we seem to be on par with libdv
in terms of time and we're doing slightly better w.r.t. to
     quality. I don't think there's much room for improvement
     left, but I'd like to try and vectorize a couple of things.
     Btw, any ideas on what may impact performance will be greatly
     appreciated.

Roman Shaposhnik ddaae6a9d1 * DV demuxer is now capable of decoding auxilary audio stream. So,
everybody who still uses second streo track for dubbing can
     now export it.

   * void* -> DVDemuxContext* change (per Fabrice's suggestion).

   * -dv1394 capture now works in all modes.

* simple/accurate implementation of dct248
   * DV encoding now supports 2-4-8 DCT
   * DV encoding gets a bit faster (but still miles away
     from what I think it could do)
   * misc. DV codec cleanups

Roman Shaposhnik 7458ccbb02 * DV handling was streamlined for both muxing/demuxing and
decoding. All muxing/demuxing functionality is now available
     in libavformat/dv.[ch].

   * dv1394.c and avidec.c were hooked up with general DV demuxer.

   * DVAUDIO is dead! Long live pcm_s16le!

   * DV audio is now always recognized -- which means we can
     now hear all those ducks quaking in pond.dv.
