* qatar/master: aacenc: Fix LONG_START windowing. aacenc: Fix a bug where deinterleaved samples were stored in the wrong place. avplay: use the correct array size for stride. lavc: extend doxy for avcodec_alloc_context3(). APIchanges: mention avcodec_alloc_context()/2/3 avcodec_align_dimensions2: set only 4 linesizes, not AV_NUM_DATA_POINTERS. aacsbr: ARM NEON optimised sbrdsp functions aacsbr: align some arrays aacsbr: move some simdable loops to function pointers cosmetics: Remove extra newlines at EOF Conflicts: libavcodec/utils.c libavfilter/formats.c libavutil/mem.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
