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.
