test/testdrawchessboard.c checks out of hg with DOS line endings on non-dos systems. Fixed via:
perl -pi -e 's/\r//g' test/testdrawchessboard.c
If the app is in landscape mode and the user presses the power button, a pause
is followed immediately by a surfaceChanged event because the lock screen
is shown in portrait mode. This triggers a "false" resume.
So, we just pause and resume following the onWindowFocusChanged events.
Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before
blocking the event pump.
