Merge remote-tracking branch 'qatar/master' 

* qatar/master:
  lavf: don't guess r_frame_rate from either stream or codec timebase.
  avconv: set discard on input streams automatically.
  Fix parser not to clobber has_b_frames when extradata is set.
  lavf: don't set codec timebase in avformat_find_stream_info().
  avconv: saner output video timebase.
  rawdec: set timebase to 1/fps.
  avconv: refactor vsync code.
  FATE: remove a bunch of useless -vsync 0
  cdxl: bit line plane arrangement support
  cdxl: remove early check for bpp
  cdxl: set pix_fmt PAL8 only if palette is available
