Moved D3D_LoadDLL and SDL_Direct3D9GetAdapterIndex to SDL_windowswindow.c at Jorgen's insistence. That file is wrapped in a more appropriate define check so it will work if somebody builds a binary without D3D support.
Added a reference to SDL_Direct3D9GetAdapterIndex to SDL_test_common.c so SDL will fail to compile if the new symbol isn't included properly. CR: Jorgen
