* qatar/master:
  mov_chan: Pass a separate AVIOContext for reading
  af_asyncts: check return value from lavr when flushing.
  mss2: simplify loop in decode_rle()
  mss12: avoid unnecessary division in arith*_get_bit()
  mss2: do not try to read too many palette entries
  mpegvideo: set AVFrame fields to NULL after freeing the base memory
  configure: Set the right cc_e flags for msvc
