There is some cleanup to be done in this package now, but I'm
deferring it until later in the cycle.
We should probably also change the semantics slightly: main should
be called for all-Go apps (that is, apps that use NativeActivity),
but it would be more consistent with buildmode=c-shared and c-archive
if we did not call main for Go shared libraries being included in
Java android apps.

Drain the event queue between ALooper_pollAll calls. ALooper_pollAll
makes an epoll to see if there is any I/O going on the underlying
resources and is relatively a costly operation. Try to consume the
queue first and block on pollAll again if necessary.
We should stop retrying if timeout occurs and return immediately.

If the looper is waking up, the current timeout limit is exceeded.
There are no external APIs to query if a looper is trying to wake up
or blocking to wait for the event data. Therefore, I'm this
change and will replace the timeout with a significantly high number
that could only be exceeded if sensor fails with a fatal problem.
The goal is not to wait on ALooper_pollAll forever.

Instead of the ad-hoc output directory structure to hold java source code
and compiled .so files, this change makes the bind command create an AAR
bundle. AAR is the format for Android library project/module outputs.
AAR is similar to .jar except that includes resource files.
http://tools.android.com/tech-docs/new-build-system/aar-format
This AAR format is in the Android's new build system's roadmap (
http://tools.android.com/tech-docs/jackandjill) and Android IDEs
are likely supporting the format.
For integration with Android Studio project, the user is expected to place
the .aar file to the main app's libs directory and specify the dependency
in the gradle rule. This can be done through a gradle plugin or with Android
Studio integration. For Buck, the .aar file can be the input of the
android_prebuilt_aar rule.
This depends on the availability of javac and android SDK -
which may not be an issue because the bind users will need them anyway
to build their main app.

Sensors package will contain APIs to read data from a wide variety
of movement, position and other physical signals.
This CL contains the initial APIs that are targeting event-based
sensors. Some of the concerns that influenced the APIs are:
- Target game developers. Latency is critical, allow output rates
up to ~10 samples per second.
- It’s rarely possible to predetermine the minimally viable sample
rate requirement of the app. - Allow users to set an upper bound rate
to avoid garbage and preserve battery life.
- Allow multiple instances of accelerometer, gyroscope, magnetometer
and altimeter sensors to be started. Optimize the share of the
underlying resources as long as it is not a bottleneck for the
sample rate.
- Prefer blocking APIs. An automatic
poll-timeout could be useful if we’re far behind the sample rate.
But, sensor initialization and waking-up significantly take longer
and there is no easy way to determine a sensor is in either one of
these states.
- Provide timestamps for each event to determine the actual rate of
the sensor data.
- Allow user to return multiple events from each call. Buffering the
events at the cost of additional latency is sometimes more
neglectable than the overhead of a function call that polls the
events one by one. Allow user to determine how many items they want
to buffer. The typical latency of a read a single event is 56 usec.
Reading 8-16 events at once has a relatively lower bound per event.
For high precision throughput, the opportunity to minimize a
function call overhead could be useful.
- Allow users to check the sensor availability on the device.
