EC-BPC: adding BPC code to Jerasure plugin
EC-BPC: refactor BPC code
EC-BPC: format layout
EC-JERASURE: rewrite region-xor function using vector operations to get ~ x1.5 speedups for erasure code
EC-BPC: extend test to run internally <n> times to get a good measurement for smalle object encodings
EC-BPC: extend test to provide a fine-grained benchmark if '--bench' is provided
EC-BPC: add assembler SSE implementation to do parity XOR over regions giving ~ x 2.5 speedup for BPC parity computations
EC-BPC: apply vector operations starting with gcc 4.4
EC-BPC: use new vector_sse_xor function for BPC parity computation
EC-BPC: guarantee that the 'decoded' map is cleaned after an decoding error and cleared before a new decoding is done
EC-BPC: fix alignment function not to create too large unnecessary bounderies to deal with vector operations
