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.

1) Limit maxEventsToWrite depending on the size of the socket
buffer allocated (Fix for write failure on manta).
2) Do not call flush() if the sensor is not activated (OEM issue).
Change-Id: I81ea78dbdef3a3773af505ca1c9a5e39492c0b48
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.

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().

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.

SensorService is dead locking itself when flush is called on older devices which don't support batching. mConnectionLock is acquired twice.
Change-Id: I5c25585bfb2b396df4b05826a9cba1da7997a3ee
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.

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.

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.

3) use uncalibrated gyro if availble for the system's sensor fusion

Auto disabled sensors get auto disabled after trigger.
An activation after this wasn't working because the
state was not being reset.

1. Some sensors can wake up the AP. Add wakelocks.
2. Handle backward compatibility for rotation vector
heading accuracy.
3. Cleanup auto disabled sensors.
4. Fix race condition between enable and dispatch.

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.

It shouldn't have caused much harm though.
Also log a warning when enabling a sensor
for a connection that is already enabled.
