In order to inhibit the screen saver, SDL currently uses
`org.freedesktop.ScreenSaver.Inhibit()` and, as a fallback, a protocol
specific method for X11 or Wayland.
Accessing `org.freedesktop.ScreenSaver` is usually not allowed when
inside a sandbox like Flatpak, unless the permission has been explicitly
granted to the application.
Another issue is that the Wayland protocol "Idle inhibit" is relatively
new and not yet widely adopted. For example Mutter still doesn't support
it.
For those reasons, when running under Flatpak or Snap, we should try to
inhibit the screen saver by using xdg-desktop-portal instead. This
should give us an higher chance of success.

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

SDL_DBus_CallWithBasicReply() allows us to send a DBus message and get
its result, if it is a basic type, e.g. integer or string.
With this function we avoid duplicating code.

If the D-Bus subsystem is shutdown and restarted mid-execution, the cached connection will be invalid. Fetch it each time that it is used to ensure that the connection is always from the current context.
This is necessary for consistent position reports with absolute mice
and improves application performance with relative mice by cutting the
number of reported mouse motion events roughly in half.
Use the xdg-desktop-portal interface to RealtimeKit1, when available, to set realtime scheduling and elevated priority for threads. This portal allows for the use of rtkit within containers such as Flatpak. It will fall back to using RealtimeKit1 directly if the xdg-desktop-portal interface is too old or not available.
The documentation doesn't state that the argument is ever modified,
and no implementation does so currently.
This is a non-breaking change to guarantee as much to callers.
* Xbox GDK support (14 squashed commits)
* Added basic keyboard testing
* Update readme
* Code review fixes
* Fixed issue where controller add/removal wasn't working (since the device notification events don't work on Xbox, have to use the joystick thread to poll XInput)
