A patch including the changes described in this ticket.

The included patch makes the following changes, which are designed to make it easier to use SDL from a Xamarin iOS project:

1. When the XAMARIN flag is defined as part of the build arguments, the main() function defined in SDL_uikitappdelegate.m is removed. The Xamarin runtime already defines a main() function, so this being present causes linker errors.

2. When the SDL_DYNAMIC_MAIN flag is defined, the following new API functions are exposed:

 * SDL_SetDynamicMain()
 * SDL_GetDynamicMain()

A C# application can use P/Invoke to pass a pointer to managed code into the SDL_SetDynamicMain() function; a simple replacement for the SDL_main function is included which will invoke this function at the necessary time.

The SDL_DYNAMIC_MAIN flag is automatically set when the XAMARIN flag is set and the target platform is iOS.
