Merge remote-tracking branch 'qatar/master'
* qatar/master: SBR DSP: fix SSE code to not use SSE2 instructions. cpu: initialize mask to -1, so that by default, optimizations are used. error_resilience: initialize s->block_index[]. svq3: protect against negative quantizers. Don't use ff_cropTbl[] for IDCT. swscale: make filterPos 32bit. FATE: add CPUFLAGS variable, mapping to -cpuflags avconv option. avconv: add -cpuflags option for setting supported cpuflags. cpu: add av_set_cpu_flags_mask(). libx264: Allow overriding the sliced threads option avconv: fix counting encoded video size.
