Merge remote-tracking branch 'qatar/master'

* qatar/master:
  rtmp: Add a new option 'rtmp_buffer', for setting the client buffer time
  rtmp: Set the client buffer time to 3s instead of 0.26s
  rtmp: Handle server bandwidth packets
  rtmp: Display a verbose message when an unknown packet type is received
  lavfi/audio: use av_samples_copy() instead of custom code.
  configure: add all filters hardcoded into avconv to avconv_deps
  avfiltergraph: remove a redundant call to avfilter_get_by_name().
  lavfi: allow building without swscale.
  build: Do not delete tests/vsynth2 directory, which is no longer created.
  lavfi: replace AVFilterContext.input/output_count with nb_inputs/outputs
  lavfi: make AVFilterPad opaque after two major bumps.
  lavfi: add avfilter_pad_get_type() and avfilter_pad_get_name().
  lavfi: make avfilter_get_video_buffer() private on next bump.
  jack: update to new latency range API as the old one has been deprecated
  rtmp: Tokenize the AMF connection parameters manually instead of using strtok_r
  ppc: Rename H.264 optimization template file for consistency.
  lavfi: add channelsplit audio filter.
  golomb: check remaining bits during unary decoding in get_ur_golomb_jpegls()
  sws: fix planar RGB input conversions for 9/10/16 bpp.
