Merge remote-tracking branch 'qatar/master'

* qatar/master:
  fix hardcoded tables compililation caused by missing math constants
  lavf: Make codec_tag arrays constant
  twinvq: give massive struct a name.
  lavf, lavu: version bumps and APIchanges for av_gettime() move
  lavfi/audio: don't set cur_buf in ff_filter_samples().
  lavfi/fifo: add audio version of the fifo filter.
  fifo: fix parenthesis placement.
  lavfi: rename vf_fifo.c -> fifo.c
  lavc: remove stats_in from AVCodecContext options table.
