Whenever a surface was attached to a context, it was dequeing a new
buffer, and enqueing it when detached. This has the effect of doing a
SwapBuffers on detach/attach cycle, which is just wrong and
occasionally caused visible glitches (e.g. animations going backwards
for one frame). It also broke some SurfaceTexture tests which
(validly) depend on specific buffer production/consumption counts.

Pass the swap interval from eglSwapInterval to the native window so it
can enable/disable SurfaceTexture's async mode. Fixes the deadlock in
SurfaceTextureGLToGLTest.EglDestroySurfaceUnrefsBuffers.

The gralloc API assumes system-wide reference counting of gralloc
buffers. The host-GL accelerated gralloc maps buffers to host-side
ColorBuffer objects, but was destroying them unconditionally in
gralloc_free(), ignoring any additional references from
gralloc_register_buffer().
This affected the SurfaceTexture gralloc buffers used by the
Browser/WebView. For some reason these buffers are actually allocated
by SurfaceFlinger and passed back to the WebView through Binder. But
since SurfaceFlinger doesn't actually need the buffer for anything,
sometime after the WebView has called gralloc_register_buffer()
SurfaceFlinger calls gralloc_free() on it. This caused the host
ColorBuffer to be destroyed long before the WebView is done using it.

The emulator EGL implementation tried to hold its own reference to
buffers acquired/released with dequeueBuffer/queueBuffer, but was
missing an incRef after dequeueBuffer during swapBuffers.
Since the native window holds a reference to the buffer between
dequeueBuffer and queueBuffer, the EGL reference isn't needed anyway.

This patches fixes a minor invalid usage of delete (instead of delete[])
and reformats the source code a little to make it more obvious.

The modules here are only built when BUILD_EMULATOR_OPENGL is defined to true
in your environment or your BoardConfig.mk (see tools/emulator/opengl/Android.mk)
