Clang 15 makes implicit function declarations fatal by default which
leads to some configure tests silently failing/returning
the wrong result.

Refactor the previous sandbox check in a standalone function that also
includes Snap support.

find_lib() uses sort -V, which is a GNU extension. Users of non-GNU
operating systems should either install GNU coreutils (assumed to
provide a gsort executable), or use the CMake build system.

This reverts commit 8553632827.
An issue with choosing the shortest one, is that it will prefer development libraries: libfoo.so is shorter then libfoo.so.0.6.
SDL makes assumption that each dynamically loaded library must have
SONAME matching pattern <libname>.so.<digit>+ hence it discards any file
that has two (or more) digits after ".so". in practice however SONAME
might be in the form of ie <libname>.so.<major>.<minor>.
as a solution keep requirement for dynamically loaded files to be named
<libname>.so.* but consider all the possibilities and prefer the shortest
one.
On filesystems with large inode numbers, such as overlayfs, attempting
to stat() a file on a 32-bit system using legacy syscalls can fail
with EOVERFLOW. If we opt-in to more modern "large file support"
syscalls, then source code references to functions like stat() are
transparently replaced with ABIs that support large file sizes and
inode numbers, such as stat64().
This cannot safely be done globally by Linux distributions, because
some libraries expose types like `off_t` or `struct stat` in their
ABI, meaning that enabling large file support would be an incompatible
change that would cause crashes. However, SDL appears to be careful to
avoid these types in header files, so it should be OK to enable this.

The use of square brackets for a character set collides with the use
of square brackets for m4 quote characters, so use the other quoting
mechanism that Autoconf provides, by escaping `[` as `@<:@` and so on.

If we're strict about applying something resembling semantic versioning
to the "marketing" version number, then we can mechanically generate
the ABI version from it.
This limits the range of valid micro versions (patchlevels) to 0-99.

For stable releases, this gives us the ability to make bugfix-only point
releases such as 2.24.1 if we want to, and distinguish between them
programmatically. For example, this ability could have been useful after
2.0.16 to fix Xwayland regressions, and after 2.0.18 to fix event loop
regressions.
For development releases, this gives us the ability to make multiple
prereleases during the same feature cycle, and distinguish between them
programmatically. For example, this would have been useful during 2.0.22
development, which went through three prereleases before reaching the
final release.

- atomic subsystem is disabled by default (changed in configure)
- SDL_WAYLAND_LIBDECOR is disabled by default if SDL_WAYLAND is not set (changed in CMakeLists.txt)
- add DUMMY-define in case the subsystem is enabled but not available (filesystem/misc/locale)
- add missing PSP/VITA-filesystem defines
- sync the order of filesystems in SDL_config.h.cmake/in
- add option to disable locale subsystem in configure
This API and implementation comes from the Unreal Engine branch of SDL, which
originally called this "SDL_ConfineCursor".
Some minor cleanup and changes for consistency with the rest of SDL_video, but
there are two major changes:
1. The coordinate system has been changed so that `rect` is _window_ relative
and not _screen_ relative, making it easier to implement without having
global access to the display.
2. The UE version unset all rects when passing `NULL` as a parameter for
`window`, this has been removed as it was an unused feature anyhow.
Currently this is only implemented for X, but can be supported on Wayland and
Windows at minimum too.
We don't use it, it was a leftover from 1.2, I think, and it doesn't exist
on Solaris, so this should hopefully fix the build there.
This also means we don't need the configure/cmake checks for
SDL_VIDEO_DRIVER_X11_CONST_PARAM_XEXTADDDISPLAY, so that was removed also.
Fixes#1666.
