This is only the first half of physical key event mapping. The
modifiers and hardware key codes will be in a followup CL. I'm
splitting this out because it covers two other parts of the problem:
first is maintaining a JNIEnv pointer for the main routine, the
second is access to the Android unicode key map. The NDK does not have
a method to give us the key mapping, so we get to it via
GoNativeActivity.
Tested with a USB keyboard. I'll attempt an abd-based unit test later,
but I suspect it will be difficult to set a device ID.

Subclassing NativeActivity makes two things possible. Firstly, we can
implement an InputConnection to offer good support for IMEs,
necessary for good keyboard support. Secondly, we can use it to
overlay WebViews onto the NativeActivity.
But to sublcass NativeActivity, we need to compile Java. To keep the
toolchain go gettable, this is done with go generate.
While here, check the exception after FindClass. Apparently it can
throw an exception.
