native-activity: complete (first-pass) port of C code to Rust

Browse Source 
At this point the C code has been fully ported to Rust but it's not yet
well integrated with the pre-existing Rust code and the port is not yet
particularly idiomatic Rust code.

/**
* The native activity interface provided by <android/native_activity.h>
* is based on a set of application-provided callbacks that will be called
* by the Activity's main thread when certain events occur.
*
* This means that each one of this callbacks _should_ _not_ block, or they
* risk having the system force-close the application. This programming
* model is direct, lightweight, but constraining.
*
* The 'android_native_app_glue' static library is used to provide a different
* execution model where the application can implement its own main event
* loop in a different thread instead. Here's how it works:
*
* 1/ The application must provide a function named "android_main()" that
* will be called when the activity is created, in a new thread that is
* distinct from the activity's main thread.
*
* 2/ android_main() receives a pointer to a valid "android_app" structure
* that contains references to other important objects, e.g. the
* ANativeActivity obejct instance the application is running in.
*
* 3/ the "android_app" object holds an ALooper instance that already
* listens to two important things:
*
* - activity lifecycle events (e.g. "pause", "resume"). See APP_CMD_XXX
* declarations below.
*
* - input events coming from the AInputQueue attached to the activity.
*
* Each of these correspond to an ALooper identifier returned by
* ALooper_pollOnce with values of LOOPER_ID_MAIN and LOOPER_ID_INPUT,
* respectively.
*
* Your application can use the same ALooper to listen to additional
* file-descriptors. They can either be callback based, or with return
* identifiers starting with LOOPER_ID_USER.
*
* 4/ Whenever you receive a LOOPER_ID_MAIN or LOOPER_ID_INPUT event,
* the returned data will point to an android_poll_source structure. You
* can call the process() function on it, and fill in android_app->onAppCmd
* and android_app->onInputEvent to be called for your own processing
* of the event.
*
* Alternatively, you can call the low-level functions to read and process
* the data directly... look at the process_cmd() and process_input()
* implementations in the glue to see how to do this.
*
* See the sample named "native-activity" that comes with the NDK with a
* full usage example. Also look at the JavaDoc of NativeActivity.
