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.
