Make GLSurfaceView handle eglSwapBuffers errors more robustly.

A careful reading of the EGL spec, as well as experience with many
different EGL drivers, has shown that it is error prone to attempt to
discriminate between different error conditions.

We now treat any error besides EGL_CONTEXT_LOST as an indication that the
EGL context is in a bad state, most likely due to the window manager
having removed the underlying surface flinger surface.

In addition, we changed the way we deal with this kind of error:
Previously we would ignore the error and keep rendering. But if the
EGL context and surface has become invalid, it would be better to
stop drawing. We now stop drawing until the surface view surface is
recreated.

See b/6032663 for an example of this problem affecting the GMM app,
but note that GMM is using their own version of GLSurfaceView, so this
change won't help them directly. They'll have to make a similar change
to their version of GLSurfaceView.
