Michael Niedermayer 2cae9809e2 Merge remote branch 'qatar/master'
* qatar/master:
  fate: fix partial run when no samples path is specified
  ARM: NEON fixed-point forward MDCT
  ARM: NEON fixed-point FFT
  lavf: bump minor version and add an APIChanges entry for avio changes
  avio: simplify url_open_dyn_buf_internal by using avio_alloc_context()
  avio: make url_fdopen internal.
  avio: make url_open_dyn_packet_buf internal.
  avio: avio_ prefix for url_close_dyn_buf
  avio: avio_ prefix for url_open_dyn_buf
  avio: introduce an AVIOContext.seekable field
  ac3enc: use generic fixed-point mdct
  lavfi: add fade filter
  Change yadif to not use out of picture lines.
  lavc: deprecate AVCodecContext.antialias_algo
  lavc: mark mb_qmin/mb_qmax for removal on next major bump.
