communication techniques bench: refactoring (1)
...
Main changes:
* change library initialization: initialization is done with
init_library once and init_thread_comm by each thread
* cont is now directly accessed by main
* list of struct communication_assoc -> array of struct thread_comm
* struct communication_channel -> struct comm_channel

* prod_idx and cons_idx aren't declared volatile so compiler could
sur-optimize access to these variable and lead to a deadlock

storage they have which could lead to sigsegv from consumer
