* qatar/master:
  mpegvideo_enc: don't use deprecated avcodec_encode_video().
  cmdutils: refactor -codecs option.
  avconv: make -shortest a per-output file option.
  lavc: add avcodec_descriptor_get_by_name().
  lavc: add const to AVCodec* function parameters.
  swf(dec): replace CODEC_ID with AV_CODEC_ID
  dvenc: don't use deprecated AVCODEC_MAX_AUDIO_FRAME_SIZE
  rtmpdh: Do not generate the same private key every time when using libnettle
  rtp: remove ff_rtp_get_rtcp_file_handle().
  rtsp.c: use ffurl_get_multi_file_handle() instead of ff_rtp_get_rtcp_file_handle()
  avio: add (ff)url_get_multi_file_handle() for getting more than one fd
  h264: vdpau: fix crash with unsupported colorspace
  amrwbdec: Decode the fr_quality bit properly
