/**
 * The user-handlerX gets invoked each time there is a new can message on connectionX, according to HW sync.
 * We put this message into a buffer, protect it from the wait, and notify the wait that
 * the new msg can be picked up. Using boost for sync.
 *
 * this handler must be connected to the CanModule access point by this wrapper in the canmodule_init call,
 * and this is hardcoded. We can have only static mutexes and cond_vars, therefore we have to decide BEFORE
 * compile-time how many reception threads we want. While in principle we can have a big number easily, let's
 * limit the number of connections ( PC port or ip-number && CAN port ) we can have PER TASK to 16.
 * This corresponds to 16 CAN buses, using i.e. one systec16 module or 8 anagate-duos.
 *
 * The user can conveniently pick up the new message from the waitForNewMessage call which
 * blocks until new reception. Just a separate thread or whatever sequence is needed for the
 * blocking reception call, the user can implement whatever scheme she likes.
