Jeff Muizelaar 1268f26df1 Bug 730898. Merge LayerView and GLSurfaceView. r=pcwalton
Once, GLThread is gone we don't have any need to support both styles of GL
rendering. Merging LayerView and FlexibleGLSurfaceView makes it clearer what's
going on, and I expect we'll also be able to take out some dead code from the
resulting LayerView.

This patch is mostly uninteresting. The interesting bits are that
implementations of requestRender and the constructors are merged. Everything
else is mostly copying over methods and renaming FlexibleGLSurfaceView's
mController to mGLController.
