6a8c461e38 Codechange: [OSX] GameLoop is really more like MainLoop 
MainLoop() is used to bootstrap OSX, where later a callback is
done to GameLoop() to execute OpenTTD. All other video drivers
don't need that, so what is in GameLoop is in MainLoop for all
other drivers. This is rather confusing. So, instead, name
GameLoop MainLoopReal to be more in sync with the other drivers.

6098811b49 Codechange: [SDL2] Split Start() in a few more functions

Reworked the code slighly while at it, to return early where
possible.
