X11 server side focus changes, such as when a focus change was requested by mutter for a globally active window, did not go through meta_display_set_input_focus(), which is responsible for emitting the `focus-window` signal. Since this signal is what triggers the display server specific code to handle focus changes, this was leading to a problem on Wayland where the focus remained on the last active Wayland window when the focus got changed to a globally active XWayland window. This commit now changes handling X11 server side focus changes to also go through the code path that emits the signal while making sure to not trigger another focus change and keeping the same serials as the previous code to not interfere with future focus changes.

Mutter
Mutter is a Wayland display server and X11 window manager and compositor library.
When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.
When used on top of Xorg it acts as a X11 window manager and compositing manager.
It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.
Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork of Clutter, a scene graph and user interface toolkit.
Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.
