* 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.
