* Add memcache limitor-support to imbufs

* Add ffmpeg-read support in anim.c and util.c
* Makes ImBufs refcountable. You can now increase an internal refcounter
  in ImBufs (using IMB_refImBuf) which is decreased by freeImBuf.
  This makes it possible to simply pass ImBuf pointers around in the
  sequencer saving a few memcopies.
