    cluster/ec: Add support for hardware acceleration
    
    This patch implements functionalities for fast encoding/decoding
    using hardware support. Currently optimized x86_64, SSE and AVX is
    added.
    
    Additionally this patch implements a caching mecanism for inverse
    matrices to reduce computation time, as well as a new method for
    computing the inverse that takes quadratic time instead of cubic.
    
    Finally some unnecessary memory copies have been eliminated to
    further increase performance.
