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/

As the implementation requires C++, the user will have to include
SDL_main.h in a C++ source file (that needs to be compiled with /ZW).
It's ok to keep the standard main() implementation in plain C and use
an otherwise empty C++ source file for the SDL_main implementation part,
if both source files #include <SDL3/SDL_main.h>
Including SDL_main.h in a C source file will print a message at
compilation (when building for WinRT or possibly other not yet implemented
platforms that require C++ for main), to remind the user of also
including it in a .cpp source file. This message/warning can be disabled
with #define SDL_MAIN_NOIMPL before including SDL_main.h in the C file.
When including it in a .cpp file, there will be a compiler error with
helpful message if it's not compiled with /ZW
For this I renamend _SDL_MAIN_NOIMPL to SDL_MAIN_NOIMPL, because now it's
not for internal use only anymore, but also useful for users (that want
their main() function in a different file than the SDL_main implementation)
Add a project for the testdraw2.c test to the WinRT solution to at least
get some minimal testing on WinRT.
I won't add all tests because it's a lot of manual clicking per test,
but this should be better than nothing :)
Also adjusted iOS demo's includes to <SDL3/..> and explicit SDL_main.h
untested, I don't have Xcode (or a Mac, for that matter)
The xcode projects (for both Xcode-iOS/ and Xcode/) will probably
have to be adjusted for the SDL_main changes to work, but now at least
the iOS demo source should work as is :)
this should hopefully make the automated builds work again
(this commit can probably be removed once all affected platforms are
converted to header-only SDL_main)
(remaining platforms will follow)
SDL_main.h is *not* included by SDL.h anymore, users are supposed to
include it directly now, usually only in the file they implement main() in.
If they need the header elsewhere or don't want SDL_main to implement
main() (but only call SDL_SetMainReady() or whatever), they
can #define SDL_MAIN_HANDLED first, same as before.
For SDL-internal usage, I added _SDL_MAIN_NOIMPL, which *also* skips the
implementation and `#define main SDL_main`, but still defines
SDL_MAIN_AVAILABLE and SDL_MAIN_NEEDED in SDL_main.h, as before.
To make the implementaion in the header shorter and avoid including windows.h,
I moved most of the Win32 SDL_main code into SDL3.dll via SDL_Win32RunApp(),
so the header-only part is just the different main functions calling
SDL_Win32RunApp(SDL_main, NULL)
Note that I changed changed the return value and type of OutOfMemory()
to return -1 instead of FALSE, so main() (or WinMain() or whatever)
returns -1 instead of 0 in case of an out-of-memory error
Compared to original Win32 SDL_main, I tweaked the part of the
implementation in SDL_main_impl.h a bit to avoid linker warnings
and conflicts with stuff from windows.h:
- replaced windows.h with own define of WINAPI
and typedef-ing HINSTANCE and LPSTR.
This prevents conflicts between all the generically-named #defines and
types in windows.h and user code (like DrawState in some SDL tests)
- only using one of main() or wmain() gets rid of a MSVC linker error
("warning LNK4067: ambiguous entry point")
If this still causes problems, we might try getting rid of wmain(),
seemed to me like MSVC can use regular main() in UNICODE mode as well
- simplified the UNICODE logic for that - while this is not exactly
equivalent to the old, it should make sense and Works For Me
This simplifies some things, clarifies some things, and also allows
for the possibility of RWops that offer non-blocking i/o (although
none of the current built-in ones do, intentionally, we could add this
later if we choose, or people could provide things like network socket
RWops implementations now, etc.
Fixes#6729.
On window focus, look up the pressed modifier keys via keycodes instead of scancodes to handle the case of remapped keys, as xkb remapping changes the associated keycode, not the scancode.
The annotations have been added to SDL_mutex.h and have been made public so applications can enable this for their own code.
Clang assumes that locking and unlocking can't fail, but SDL has the concept of a NULL mutex, so the mutex functions have been changed not to report errors if a mutex hasn't been initialized. We do have mutexes that might be accessed when they are NULL, notably in the event system, so this is an important change.
This commit cleans up a bunch of rare race conditions in the joystick and game controller code so now everything should be completely protected by the joystick lock.
To test this, change the compiler to "clang -Wthread-safety -Werror=thread-safety -DSDL_THREAD_SAFETY_ANALYSIS"
This was still conditional on whether SDL2::SDL2-static exists, but
it's now SDL3 that matters.

Some of these are probably unnecessary now that Autotools (with its
optional in-tree builds) has been deleted in favour of CMake (with
mandatory out-of-tree builds), but let's be consistent.
Spotted while doing a `git grep` for other bugs of the same form as #6801.

It was previously thought that these function calls were unnecessary as the initial bug and reproduction case that necessitated their addition seemed to be fixed, but apparently there are still cases where this needs to be set explicitly. Set the xdg surface geometry at creation time and when the window size changes.
Partially reverts #6361. This is not needed in the libdecor path, as libdecor calls this for the content surface internally.
* N3DS: Make Sem waits cooperative friendly.
The 3DS has a cooperative threading model. Sleeping after TryWait and
WaitTimeout avoid starving other threads. It inccurs a runtime penalty,
but it's better than having to hard reset your console to recover from
a deadlock.
