* qatar/master:
  configure: add functions for testing code fragments
  af_amix: avoid spurious EAGAIN.
  af_amix: return AVERROR(EAGAIN) when request_frame didn't produce output.
  af_amix: only consider negative return codes as errors.
  avconv: use only meaningful timestamps in start time check.
  avconv: fix the check for -ss as an output option.
  mss3: add forgotten 'static' qualifier for private table
  lavc: options: add planar names for request_sample_fmt
  flacdec: add planar output support
  flvdec: Treat all nellymoser versions as the same codec

Conflicts:
	ffmpeg.c
