SDL.h now exists solely as a header that includes everything else, instead
of one that forces you to include everything else when you just want the
declaration for SDL_Init().
Fixes#6840.
This fixes the following error:
error: PCH file was compiled for the target 'thumbv7-none-linux-android16' but the current translation unit is being compiled for target 'armv7-none-linux-android16'
LINKER_LANGUAGE needs to be used as following:
Usage
cmake [options] <path-to-source>
cmake [options] <path-to-existing-build>
cmake [options] -S <path-to-source> -B <path-to-build>
Specify a source directory to (re-)generate a build system for it in the
current working directory. Specify an existing build directory to
re-generate its build system.
Run 'cmake --help' for more information.
Haiku does not not this property explicitly set because CMake knows .cc files are c++
Make sure the window framebuffer is cleaned up before shutting down OpenGL, as it might be implemented using an OpenGL texture.
Fixes this call stack:
```
(gdb) p _this
$1 = (SDL_VideoDevice *) 0x42e360
(gdb) p _this->egl_data
$2 = (struct SDL_EGL_VideoData *) 0x0
```
```

This was a legitimate bug, thank you clang!

(cherry picked from commit 3b0cd441584ada86c4456afb4e8b3edaf2173073)
makes the SDL_main code shorter
Also added a generic SDL_RunApp() implementation for platforms that
don't really need it.
Some platforms (that use SDL_main but haven't been ported yet) are
still missing, but are added in the following commits.
and move the #undef main and #define main SDL_main to the start/end of
SDL_main_impl.h instead of repeating it in every platform implementation
Thanks to SDL_N3DSRunApp we don't need the #include <3ds.h> in
SDL_main_impl.h - that caused conflicts with testthread.c, because both
have (different) ThreadFunc typedefs.
and update README-visualc.md and README-gdk.md accordingly
Also moved src/main/windows/version.rc to src/core/windows/
and adjusted VS solutions, CMakeLists.txt and versioning scripts
in build-scripts/ accordingly.
This will eventually allow us to remove all of src/main/
