This pull request adds an implementation of a Vulkan Render backend to SDL. I have so far tested this primarily on Windows, but also smoke tested on Linux and macOS (MoltenVK). I have not tried it yet on Android, but it should be usable there as well (sans any bugs I missed). This began as a port of the SDL Direct3D12 Renderer, which is the closest thing to Vulkan as existed in the SDL codebase. The shaders are more or less identical (with the only differences being in descriptor bindings vs root descriptors). The shaders are built using the HLSL frontend of glslang.
Everything in the code is pure Vulkan 1.0 (no extensions), with the exception of HDR support which requires the Vulkan instance extension `VK_EXT_swapchain_colorspace`. The code could have been simplified considerably if I used dynamic rendering, push descriptors, extended dynamic state, and other modern Vulkan-isms, but I felt it was more important to make the code as vanilla Vulkan as possible so that it would run on any Vulkan implementation.
The main differences with the Direct3D12 renderer are:
* Having to manage renderpasses for performing clears. There is likely some optimization that would still remain for more efficient use of TBDR hardware where there might be some unnecessary load/stores, but it does attempt to do clears using renderpasses.
* Constant buffer data couldn't be directly updated in the command buffer since I didn't want to rely on push descriptors, so there is a persistently mapped buffer with increasing offset per swapchain image where CB data gets written.
* Many more resources are dependent on the swapchain resizing due to i.e. Vulkan requiring the VkFramebuffer to reference the VkImageView of the swapchain, so there is a bit more code around handling that than was necessary in D3D12.
* For NV12/NV21 textures, rather than there being plane data in the texture itself, the UV data is placed in a separate `VkImage`/`VkImageView`.
I've verified that `testcolorspace` works with both sRGB and HDR linear. I've tested `testoverlay` works with the various YUV/NV12/NV21 formats. I've tested `testsprite`. I've checked that window resizing and swapchain out-of-date handling when minimizing are working. I've run through `testautomation` with the render tests. I also have run several of the tests with Vulkan validation and synchronization validation. Surely I will have missed some things, but I think it's in a good state to be merged and build out from here.
It is becoming necessary to enable additional features as libdecor continues to evolve, and checking against a single base version will no longer be adequate. Libdecor doesn't provide versioning defines in its headers, so split the version string into parts to allow for discrete version detection and feature enablement at build time.
At the point that we run this, nothing SDL-specific is set up yet.
__APPLE__ is a compiler predefined macro that forms part of the API on
Apple platforms, so it's fine to rely on it.
This partially reverts commit 31d133db.

These were added a very long time ago and seem to serve no purpose now, as the functionality they provided is now in core Wayland protocols, current information on their usage and status is nonexistent, no modern compositor seems to support them, and the code paths are untested and subject to bit-rot at this point. It also causes duplicate symbol issues when statically linking an application to both Qt and SDL.
This reverts commit 6fd0613ac8.
Turns out that the Steam Runtime is still on PulseAudio 1.1, and the only
thing we (currently) need a newer Pulse for is pa_threaded_mainloop_set_name,
so let's just go back to treating that symbol as optional.
We might need to force a higher version at some point, but it's not worth it
over this.
main features:
- No more sdl-build-options/sdl-shared-build-options/sdl-global-options
- Dependency information is stored on SDL3-collector for sdl3.pc
- Use helper functions to modify the SDL targets;
- sdl_sources to add sources
- sdl_glob_sources to add glob soruces
- sdl_link_dependency to add a link dependency that might also
appear in sdl3.pc/SDL3Config.cmake
- sdl_compile_definitions to add macro's
- sdl_compile_options for compile options
- sdl_include_directories for include directories
They avoid repeated checks for existence of the SDL targets
- A nice feature of the previous is the ability to generate
a sdl3.pc or SDL3Config.cmake that describes its dependencies
accurately.
various:
- remove duplicate libc symbol list
- add CheckVulkan
- remove unused HAVE_MPROTECT
- add checks for getpagesize
Adds the SDL_EVENT_WINDOW_OCCLUDED events and the window flag SDL_WINDOW_OCCLUDED to report when the window occlusion state has changed, so that the application can take appropriate measures, as it may wish to suspend drawing, throttle, or otherwise behave in a more energy efficient manner when the window is not visible. When the window is no longer occluded, the SDL_EVENT_WINDOW_EXPOSED event is sent and the occlusion flag is cleared.
This is handled on macOS via the window occlusion state event (available as of 10.9), and via the xdg-shell protocol on Wayland (version 6, wayland-protocols 1.32, passed through in libdecor 0.1.2).
- SDL_AudioCVT is gone, even internally.
- libsamplerate is gone (I suspect our resampler is finally Good Enough).
- Cleanups and improvements to audio conversion interfaces.
- SDL_AudioStream can change its input/output format/rate/channels on the fly!

On Fedora, the headers for 32-bit and 64-bit are shared.
When building a 32-bit library, CMake found the header (that was installed
for the 64-bit libsamplerate development package). Because no 32-bit libsamplerate
library was installed, linking failed. (SDL_LIBSAMPLERATE_DYNAMIC was set to FALSE
because CMake could not find a library)
libdecor plugins can change the min/max window size values internally to enforce a minimum window size, and errors and crashes can result if the window size is below the internal limit.
On versions of libdecor >= 0.1.1, the minimum width and height can be queried and the minimum required window size will be enforced. The application requested window size is still respected, however, the actual window may be slightly larger than the drawable area to accommodate the required libdecor minimum size.
On version 0.1.0 of libdecor, which lacks the function to retrieve the minimum size, the internal limits are overridden before committing a frame, so that the internal limits always match the window size as a workaround, even if the window is technically smaller than the plugin would normally allow.
