Revert all recent GLSurfaceView changes.

Several issues have been identified that will need to be
resolved carefully before we attempt to make similar changes.

1. Some applications make assumptions about the fact that all
   Runnables posted with queueEvent() will be executed before
   the next draw.  Because the Choreographer may post messages
   in the past (due at the frame time), these Runnables were
   not always running at the expected time.

2. Some applications apparently hijack the GLThread and try
   to run their own Looper on it.  This obviously won't work
   if we are already running one of our own.

We may need to add new rendering modes or target API checks
to provide an opportunity for applications to opt-in to the
changes in the future.
