Android: create Pause/ResumeSem semaphore at higher level than CreateWindow()

Browse Source 
- If you call onPause() before CreateWindow(), SDLThread will run in infinite loop in background.

- If you call onPause() between a DestroyWindow() and a new CreateWindow(), semaphores are invalids.

SDLActivity.java: the first resume() starts the SDLThread, don't call
nativeResume() as it would post ResumeSem. And the first pause would
automatically be resumed.
