This implements a new API for EC modules to define MKBP event sources and send MKBP event to the AP. Also, a new host command EC_CMD_GET_NEXT_EVENT is added for the AP to query the pending MKBP events. Each event type may have custom event data sent along with the event. BRANCH=None BUG=chrome-os-partner:33194 TEST=Enable MKBP event on Ryu. Set a host event from EC console, run 'ectool nextevent', and see MKBP event 0x01 (HOST_EVENT) and the set host event.
