Provide a new method, GLSurfaceView.setEGLContextClientVersion. Clients
call this method to define which level of OpenGL ES support they want.
This method only affects the default behavior of GLSurfaceView. If clients
have supplied their own EGLContextFactory or EGLConfigChooser then they
are on their own if they want to create an OpenGL ES 2.0 context.
This API is currently hidden.
Update the gl2_java test to use this new API.
Update the gl2_java test's AndroidManifest.xml file to indicate that
it requires OpenGL ES 2.0.
+ The mDone flag is now a pair of flags: mShouldExit and mExited. The
problem with mDone was that it meant "had been asked to exit", but was
being used by some observers as "had exited". Using two variables means
that observers can observe either "had been asked to exit" or "had exited",
as they prefer.
+ Simplyify where we check for mShouldExit. We now check for it at the
top of our innermost guardedRun while loop.
+ requestExitAndWait now waits for mExited to be set to true to know
that a thread has exited, rather than using join(). This means we can use
wait() for the check, which releases the sGLThreadManager
monitor, avoiding a potential deadlock.
+ move the event queue into the sGLThreadManager monitor. This avoids
having to acquire two locks in order to enque/deque events, which also
avoids the potential for lock ordering deadlocks.
+ Simplify the event dequeueing code. We now deque one event each time
through the main GLSurfaceView loop. Events still have priority over
rendering, so there isn't any semantic change, it just cleans up the code.
+ Avoid trying to acquire an egl Surface if we're paused.
+ To simplify reasoning about the code, call sGLThreadManager.notifyAll()
in every case where we modify one of the variables that's protected by
the sGLThreadManager monitor. It would be slightly more efficient to only
notify when we change variables that could cause a thread to wait(), but
then we would have to redo our analysis every time we change any code.
+ Clean up the logic for creating the EGL surface and then calling the
renderer's onSurfaceCreated / onSurfaceChanged methods.
+ Implement work-around for bug 2263168 "Need to draw twice after
screen rotation..."

There were potential deadlocks between the per-GLThread monitors and the
GLThreadManager monitor.
To avoid these deadlocks we now use a single monitor for
both the GLThreadManager state and the per-GLThread state.
Converted GLThreadManager's semaphore into the equivalent
synchronized-wait-notifyAll code. This enables us to wait for
either mDone, or user events, or the EGL surface with a single "wait()".
Simplified the logic used to acquire and release the EGL surface. The
EGL surface is now only requested while the surfaceFlinger surface
is acquired.
Removed the "egl surface stealing" policy we had recently inserted.
It's not needed now that we reliably quit when requested.
Pulled user event processing outside of the GLThreadManager monitor
so that we don't call any potentially-long-running code while
inside the monitor.
This should help with bug 2228262.

Merge commit '3f857b78fc68e5d700139bdc6078c5333b62a9bc' into eclair-plus-aosp
* commit '3f857b78fc68e5d700139bdc6078c5333b62a9bc':
Allow a GLThread to release and reacquire the EGL Surface as needed.
We currently only allow one GLThread to have an active EGL Surface at a
time.(This may be lifted in the future, when EGL and GL are reentrant.)
Prior to this change we would enforce this rule by having older GLThreads
quit when a new GLThread started. That had the drawback of leaving the
older GLSurfaceViews in a zombie state -- their GLThreads would be
gone.
We now enforce this rule by just releasing and reacquiring the EGL surface
context as needed.
Specific changes to the code:
created private helper methods - startEgl and stopEgl to help manage
starting and stopping EGL.
Move the calls to sGLThreadManager start and end from the outermost run
method into the startEgl / stopEgl methods.
Reworked the wait loop to handle starting and stopping EGL as needed.
needToWait() gets simpler -- just looks at current status.
sGLThreadManager.shouldQuit was replaced by shouldHaveEgl.
This is another step in fixing bug 2228262.
