crypto: sha-mb - multibuffer crypto infrastructure
This patch introduces the multi-buffer crypto daemon which is responsible for submitting crypto jobs in a work queue to the responsible multi-buffer crypto algorithm. The idea of the multi-buffer algorihtm is to put data streams from multiple jobs in a wide (AVX2) register and then take advantage of SIMD instructions to do crypto computation on several buffers simultaneously. The multi-buffer crypto daemon is also responsbile for flushing the remaining buffers to complete the computation if no new buffers arrive for a while.
