e74baf6ca7 SensorService fixes.
i) Add more debug stats (acks needed, acks received)
  ii) Comment out write failure message.

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.

56ae42613c SensorService performance improvements.
i) Send ack for wake_up sensors on the socket connection instead of using Binder RPC.
  ii) Cache events per connection in case there are write failures. Compute cache size
      from FIFO counts of sensors.
 iii) Send FlushCompleteEvent only for apps that explicitly called flush().

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.

i) SensorService dropping events. Increase SOCKET_BUFFER_SIZE in BitTube ctor.
ii) Call flush before every activate.
iii) Emulate flush for older devices. Add a trivial flush complete event when flush is called.

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.

ac9a96da65 fix a dead-lock in sensorservice
sensorservice would deadlock if for some reason
a sensor failed to enable.

simplifed the code a bit, and made it behave a little
closer to mr1.1 -- I couldn't convince myself that
some changes in how locks were used were correct.

787ac1b388 improve sensor battery usage tracking
until now we were tracking when a sensors was
physically enabled or disabled and we were reporting
that to the BattaryService.

this wasn incorrect because we could have several different
apps enabling the same sensor, so the accounting by the
battery service would be incorrect in that case (depending
on the order in which these apps disabled said sensor).

BatteryService tracks sensors per uid, however SensorService
does this per binder connection, so we could have several
binder connections for the same uid, to solve this we keep
a list of sensor/uid -> count, which is the bulk of this
change.
