SensorService fixes.
1) Flush should only be received by the app calling flush(). Maintain
a queue of all flush() calls and send flush_complete events in that
order.
2) Log warnings for older HALs. Remove batch() calls with DRY_RUN flag.
3) Reallocate event cache when more sensors register and the desired
maxCacheSize increases. Clear NEEDS_ACK flag in the buffer whenever
there is a write() failure.
4) More dump information. Add wake-up flag, maxDelay and timestamps for
sensor events.
