Merge remote-tracking branch 'qatar/master'

* qatar/master:
  lavf: Detect discontinuities in timestamps for framerate/analyzeduration calculation
  lavf: Initialize the stream info timestamps in avformat_new_stream
  id3v2: Match PIC mimetype/format case-insensitively
  configure: Rename check_asm() to more fitting check_inline_asm()
  fate: Only test enabled filters
  avresample: De-doxygenize some comments where Doxygen is not appropriate
  rtmp: split chunk_size var into in_chunk_size and out_chunk_size
  rtmp: Factorize the code by adding find_tracked_method

Conflicts:
	configure
