Merge remote-tracking branch 'qatar/master'
* qatar/master: libx264: fix indentation. vorbis: fix overflows in floor1[] vector and inverse db table index. win64: add a XMM clobber test configure option. movdec: Parse the dvc1 atom ARM: ac3: fix ac3_bit_alloc_calc_bap_armv6 swscale: K&R formatting cosmetics for Blackfin code frwu: lowercase the FRWU codec name movdec: fix dts generation in fragmented files fate: make acodec-ac3_fixed test output raw AC3 APIchanges: add missing commit hashes swscale: implement MMX, SSE2 and AVX functions for RGB32 input. ra144enc: drop pointless "encoder" from .long_name bethsoftvideo: fix palette reading. mpc7: use av_fast_padded_malloc() mpc7: simplify handling of packet sizes that are not a multiple of 4 bytes doc: decoding Forward Uncompressed is supported Fix a typo in the x86 asm version of ff_vector_clip_int32() pcmenc: Do not set avpkt->size. ff_alloc_packet: modify the size of the packet to match the requested size Conflicts: doc/APIchanges libavcodec/libx264.c libavcodec/mpc7.c libavformat/isom.h libswscale/Makefile libswscale/bfin/yuv2rgb_bfin.c tests/ref/fate/bethsoft-vid tests/ref/seek/ac3_ac3 Merged-by: Michael Niedermayer <michaelni@gmx.at>
