  http: Increase buffer sizes to cope with longer URIs
  nutenc: const correctness for ff_put_v_trace/put_s_trace function arguments
  h264_refs: Fix debug tprintf argument types
  golomb: const correctness for get_ue()/get_se() function arguments
  get_bits: const correctness for get_bits_trace()/get_xbits_trace() arguments
