Get decoding diagnostic request from decoding thread of can_bus_t
Decoding divided in 2 subfunctions dedicated to decode either pure CAN messages or diagnostic (obd2) message. About now, a diagnostic request has a name then it will be pushed on the event_queue as a SimpleMessage. Without name full details of diagnostic response will be pushed as diagnostic response. This behavior follows the one from OpenXC. Change-Id: I255f3f6487fa9511ea47c74606014995a7b0f720 Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>
