The input queue runs concurrent with the native activity lifecycle,
and so the getKey helper Java method might be called after the
app has been destroyed. This is particularly likely for "back"
key presses that destroys activities.
Change the getKey method to be static so that it can be called
outside the app lifecycle.
Run `go generate ./cmd/gomobile` to update the compiled dex file that
contains GoNativeActivity.

The OpenGL C function glTexImage2D has the following signature:
void glTexImage2D(GLenum target,
GLint level,
GLint internalFormat,
GLsizei width,
GLsizei height,
GLint border,
GLenum format,
GLenum type,
const GLvoid * data);
However, the corresponding Context.TexImage2D method in package gl
does not include the internalFormat parameter, and use the format
argument instead. That's ok for many texture formats; for example,
RGBA textures have both format and internalFormat set to GL_RGBA.
But not always. In particular, OpenGL ES 3 allows the use of sRGB
encoded textures by specifying GL_SRGB8_ALPHA8 as internalFormat,
but keeping GL_RGBA as format.
Add the internalFormat to the Context package. This is unfortunately
a breaking change, but adding a new function ("glTexImage2D2"?) to
Context is too ugly for a parameter that should have been there all
along. (Adding a new method to the Context interface is technically
also a breaking change, but I don't expect that there are any
external implementers of the interface).

CL 122897 changed the visibility of the global JavaVM, JNIEnv and
android.context.Context variables to be internal to gomobile.
However, users of gomobile build programs used those internal
variables to access Java API through Cgo and JNI without Java code.
Make an exported version of mobileinit.RunOnJVM available. This is
quite possibly not the right API for this, but I don't have the
bandwidth to design a better solution. On the other hand, without
access to Java APIs, gomobile build programs are unfairly forced to
add Java code where before there were no need.

Android runs a finalizer watchdog that tracks the running time of
finalizers and throws an exception if any runs too long. Our
finalizers do very little work and as such are not affected by the
timeout. However, there has been reports, for example:
https://stackoverflow.com/questions/24021609/how-to-handle-java-util-concurrent-timeoutexception-android-os-binderproxy-fin
that the watchdog does not take into account periods where the device
goes to sleep in the middle of a finalizer run. So if a given app runs
in the background, the Java GC starts a finalizer and the device goes
to sleep before it returns, an exception will crash the app if the sleep
period extends the watchdog timeout.
The problem might be fixed on some newer version of Android, but the
problem is reported for as late as Android 6.
The suggested workaround is to use PhantomReferences and run a
background thread that take dead references off a ReferenceQueue and
perform cleanup.
This CL builds on the previous CL and splits up the Ref class so Refs
only reference counts Java objects, while a new class GoRef tracks Go
references. The Go references are wrapped in PhantomReferences that in
turn appear on a GoRefQueue to be cleaned up by a background (daemon)
Thread.

Today, the Seq.Ref class has two purposes. For Java references,
Ref contains the refnum, a reference to the Java object and a
reference count. For Go references, Ref contains the refnum and
its finalizer makes sure to decrement the reference count on the Go
side.
The next CL will replace the use of finalizers with an explicit
ReferenceQueue of Go references, and the Ref class will no longer
be used for Go refences. To prepare for that, this CL pulls up the
construction of Go referencing Ref instances into the Seq.trackGoRef
function.

Standalone toolchains fixes the 24058 build and is the official way
to build Android programs. So gomobile should be less affected by
future changes in the NDK toolchain internals.
Create the standalone toolchains with gomobile init.
With the new Go 1.10 build cache, the prebuild work by the gomobile
init command is useless. Use the opportunity to simplify init to
only creating NDK toolchains and, optionally, building OpenAL for
Android. With that, it is no longer necessary to use gomobile init
