i) Call removeFd() only if the fd in the BitTube has been
previously added to the Looper. Use a flag to determine whether the fd
has been previously added or not.
ii) Increment mPendingFlushEventsToSend after holding a connectionLock.
iii) Store the number of acks that are pending in SensorEventQueue
and send them all at once.

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.

90ed3e8d7883d9c80fb8bf11b1c593bd8b2b39d0 10-Sep-2013 Mathias Agopian <mathias@google.com> 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.

- In SensorEventQueue, only bail on errors from Looper::loopOnce
- Improve sensor error logging

59abe7e0909bf4b7bf7b9601e1e40a05f6d4fd8a 14-Sep-2010 Jeff Brown <jeffbrown@google.com> 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.

45e0acb41acf30a1b7592ea7e695d96aca3ccd3b 08-Sep-2010 Dianne Hackborn <hackbod@google.com> Modify native ALooper to take an explicit ident.

The ALooper API now uses an explicit "identifier" for the integer
that is returned rather than implicitly using the fd. This allows
the APIs that had the fd to be a little more sane.

a48bcf62b6a26f24a0bdd2b44bb39fadce499e92 30-Jul-2010 Mathias Agopian <mathias@google.com> 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

a7352c9f4a6e642c29782b19db5bc0bd98feddc8 15-Jul-2010 Mathias Agopian <mathias@google.com> new SensorService

on top of the new (native) SensorManger API.

589ce85ee4174829cfedce91b6b2509d2a4002eb 14-Jul-2010 Mathias Agopian <mathias@google.com> 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

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