Add native algo from OpenMP stream extension
...
Add native algorithm from OpenMP stream extension. This require adding
one function in commtech.h: end_producer(). This function does nothing
for all communication algorithm but gomp_stream (the algorithm added by
this commit).

[commtech] Refactor to chain more than 2 nodes
...
* Refactor the source to be able to chain more than 2 nodes together
* Compile all binaries by default (binList must be set manually in
lancement.sh to run only a subset of the binaries

[commtech] Varying size of buffer for BatchQueue
...
Create several variation of BatchQueue, each with a different buffer
size: batch_queue_1024, batch_queue_512, ..., batch_queue_2.

[commtech] Fix cache line size
...
Cache line size in current processors (at least the one used for tests:
cerclon) is 64 bytes, not 128. Thus modifying the declaration in
commtech.h

Split CSQ in 2 communication techniques.
...
* 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)
