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.
Fixes: 31d133db "Define SDL_PLATFORM_* macros instead of underscored ones (#8875)"

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 fixes a warning that could show up on some MS linkers which use a
slightly different warning message than expected.
Amends check_linker_supports_version_file to include the "unrecognized
option" warning message.
This reverts commit 6fd0613ac841b2e4384ded3097a6453b7b7b5e53.
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.
Previously, `open()` was used with the default option of `newline=None`,
which means that “any '\n' characters written are translated to the
system default line separator”. Now, `xxd.py` always writes `\n` line
endings. This eliminates the need for the .gitattributes file.
The ability to pass a pathlib.Path to open() was new in Python 3.6,
and the oldest branch of the Steam Runtime only has Python 3.5 available.
Even without considering retrocomputing, using the Path.open method is
more consistent with how we read the input 2 lines earlier.

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!
