* Provide for BatchQueue, CSQ, FastForward, MCRingBuffer and GOMP stream
a version using 64 cache lines in total for all buffers.
* Rename common version from _common_comm.h to _common.h to avoid
considering them as communication technique on their own
* Divide CSQ in 2 communication techniques: one with 2 slots (as in
BatchQueue aka c_cache) and one with 64 slots (as in the article)
* Rename fake communication technique in none communication technique
and disable any activity (send no longer does anything)
