Merge remote branch 'qatar/master'

* qatar/master:
  graphparser: add a NULL check on the argument passed to strstr
  setdar: prefer "sar" over "par" in log info message
  fade: fix draw_slice() check on fade->factor value
  fade: make draw_slice() chroma check against planes 1 and 2
  win32: include the correct header in cmdutils.c
  ac3: fix memleak in fixed-point encoder
  flashsv: Return more meaningful error values.
  flashsv: Employ explicit AVCodec struct initializers.
  read AVI palette from the end of extradata
  cosmetics: K&R coding style and more whitespace for Flash Screen Video
