Use a queue now for sync events, this will allow multiple interrupts to be called before the motion sense task executes. The events (including timestamps) get stored in a small queue. 8 events for the queue size should be plenty, most applications will have latency concerns anyway once we get a couple of queued up events. Also changed the init function to be a little bit more robust to race conditions. Added count argument to the "sync" simulation command to test the queue behavior. BRANCH=master BUG=b:73551961, b:67743747 TEST="sync 4" yields 4 events on the AP, whereas before it would only give the AP the last event.
