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.
