SDL has been building on GNU/Hurd for a long time, using either drivers
based on external libraries (e.g. X11, pulseaudio, sndio, etc) or dummy
drivers. This commit introduces it explicitly as platform, so it can be
recognized, and tweaked as needed. In particular:
- introduce the SDL_PLATFORM_HURD define
- tighten/improve the platform detection in cmake, and use "Hurd" as
identifier
- return the platform name in SDL_GetPlatform()
- tweak the CFLAGS/LDFLAGS so pthreads can be used properly
- implement SDL_GetExeName(), using /proc/self/exe as provided by the
basic Linux-like procfs
- enable GLES 2 in tests (mostly for consistency with Linux)
- Removed GTK signal handler in x11settings. XSettings events are now properly dispatched to X11_XsettingsNotify.
Previously events were not being passed to xsettings-client as no SDL xsettings_window was created. Now all events
are filtered through xsettings_client_process_event allowing it to process the external window events that are selected.
Global content scale is updated for changes to any recognized dpi settings.
- X11_GetGlobalContent now reads the current RESOURCE_MANAGER prop off of the root window to ensure it sees the
current value. XResourceManagerString is now only used if getting the current prop fails as it caches the current resource
manager value per-display connection.
- Clean up some warnings in SDL_gtk.
- gtk_init_check claims it will not terminate the program on failure, however this is does
not apply to the internal check it performs to see whether another GTK library is already
loaded, the detection of which triggers a g_error which glib treats as fatal.
- gtk_progress_get_type and gtk_misc_get_type are checked to match the checks done
by _gtk_module_has_mixed_deps.
- Clean up gtk/gdk loading. There are no library fallbacks so the one option available can
be loaded rather than iterating through a list of one item.
The Wayland keyboard repeat code assumes that if we have a certain timeout then we'll wait at least that long, and generate a key repeat event on timeout. If we wait a shorter time, we won't generate a key repeat event and then return 0, even if we were supposed to wait indefinitely.

Removed duplicate hints SDL_HINT_APP_NAME, SDL_HINT_APP_ID, and
SDL_HINT_AUDIO_DEVICE_APP_NAME.
Wired up a few things to use the metadata; more to come!
Fixes https://github.com/libsdl-org/SDL/issues/4703
Consolidate the X11_WMCLASS and WAYLAND_WMCLASS envvars into one SDL_HINT_APP_ID hint. This hint serves the same purpose on both windowing systems to allow desktop compositors to identify and group windows together, as well as associate applications with their desktop settings and icons.
The common code for retrieving the value is now consolidated under core/unix/SDL_appid.c as it's common to *nix platforms, and the value is now retrieved at window creation time instead of being cached by the video driver at startup so that changes to the hint after video initialization and before window creation will be seen, as well as to accommodate cases where applications want to use different values for different windows.
I updated .clang-format and ran clang-format 14 over the src and test directories to standardize the code base.
In general I let clang-format have it's way, and added markup to prevent formatting of code that would break or be completely unreadable if formatted.
The script I ran for the src directory is added as build-scripts/clang-format-src.sh
This fixes:
#6592#6593#6594
I ran this script in the include directory:
```sh
sed -i '' -e 's,#include "\(SDL.*\)",#include <SDL3/\1>,' *.h
```
I ran this script in the src directory:
```sh
for i in ../include/SDL3/SDL*.h
do hdr=$(basename $i)
if [ x"$(echo $hdr | egrep 'SDL_main|SDL_name|SDL_test|SDL_syswm|SDL_opengl|SDL_egl|SDL_vulkan')" != x ]; then
find . -type f -exec sed -i '' -e 's,#include "\('$hdr'\)",#include <SDL3/\1>,' {} \;
else
find . -type f -exec sed -i '' -e '/#include "'$hdr'"/d' {} \;
fi
done
```

Add a new flag to avoid suppressing EINTR in SDL_IOReady(). Pass the
flag in WaitEventTimeout() to ensure that a SIGINT will wake up
SDL_WaitEvent() without another event coming in.

HAVE_POLL is correctly defined in SDL_config.h when running configure. However, in the only place where it's used, it's undefined at the start of the file.
