Subject: [PATCH] Android: fixed immediate transition to pause and resume.

"Pause" transition will add events:
 SDL_WINDOWEVENT_ENTER
 SDL_WINDOWEVENT_FOCUS_LOST
 SDL_WINDOWEVENT_MINIMIZED
 SDL_APP_WILL ENTER BACKGROUND
 SDL_APP_DID ENTER BACKGROUND

"Resume" transition will add events:
 SDL_APP_WILL ENTER FOREGROUND
 SDL_APP_DID ENTER FOREGROUND
 SDL_WINDOWEVENT_FOCUS_GAINED
 SDL_WINDOWEVENT_RESTORED

If Android application doesn't empty the event loop in between, it enters in
"paused" state when SDL_WINDOWEVENT_RESTORED is fetched.

See bug 3250 for pratical case.
