9e3adfcebf SensorService flush fixes.
i) Fix a possible race condition when adding a pending flush connection
 to mActiveSensors data structure.
 ii) Invalidate flush_complete_events as soon as they are consumed by a
 connection so that they are not used by other connections which are
 registered for the same sensor.

6c2664ae34 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.

9a844cf78f Enable wakeup sensors.
SensorService should hold a wakelock till the app reads events from a wakeup sensor. Currently drivers hold a wakelock with a
timeout while delivering events from a wake up sensor like Significant Motion. This hack can be removed now.

90ed3e8d78 fix a few problems with BitTube
BitTube used to send objects one at a time and didn't
handle errors properly.

We now send all the objects in one call, which means they
have to be read as a single batch as well. This changes the
BitTube API.

Update SensorService to the new API.

Also added an API to set the size of the send buffer.

59abe7e090 Replace epoll() with poll() and rename PollLoop to Looper.
As part of this change, consolidated and cleaned up the Looper API so
that there are fewer distinctions between the NDK and non-NDK declarations
(no need for two callback types, etc.).

Removed the dependence on specific constants from sys/poll.h such as
POLLIN.  Instead looper.h defines events like LOOPER_EVENT_INPUT for
the events that it supports.  That should help make any future
under-the-hood implementation changes easier.

Fixed a couple of compiler warnings along the way.

a48bcf62b6 Added SensorManager.getMinDelay()
Exposed the new "min delay" sensor property through native and
java sensor apis. This allows the caller to know what is the
maximum rate at which a sensor can return events, or, if a sensor
works in "update" mode (events returned only when the value changes).

Also augmented SensorManager.regusterSensorEvent() so that it can
accept a value in microsecond in addition to the 4 constants already
defined.

a7352c9f4a new SensorService
remove old sensor service and implement SensorManager
on top of the new (native) SensorManger API.

589ce85ee4 first step at implementing the native sensor support
in this commit:
- implemented the C stub
- implemented the binder interfaces involved
- implemented most of the C++ client side

missing:
- SensorManager cannot connect to the SensorServer yet
(because there is no SensorServer yet)
