Fixed bug 4246 - Android: orientation between portrait<->landscape doesn't work 

Improve handling of landscape/portrait orientation. Promote to SCREEN_ORIENTATION_SENSOR_* when needed.
Android window can be somehow resizable.
If SDL_WINDOW_RESIZABLE is set, window size change is allowed, for instance when orientation changes (provided the hint allows it).
