    xfixes: Add ClientDisconnectMode
    
    The Xserver itself is capable of terminating itself once all X11 clients
    are gone, yet in a typical full session, there are a number of X11
    clients running continuously (e.g. the Xsettings daemon, IBus, etc.).
    
    Those always-running clients will prevent the Xserver from terminating,
    because the actual number of X11 clients will never drop to 0.
    
    To solve this issue directly at the Xserver level, this add new entries
    to the XFixes extension to let the X11 clients themselves specify the
    disconnect mode they expect.
    
    Typically, those X11 daemon clients would specify the disconnect mode
    XFixesClientDisconnectFlagTerminate to let the Xserver know that they
    should not be accounted for when checking the remaining clients prior
    to terminate.

+13. Disconnect mode
+
+The X11 server is capable of terminating itself once all X11 clients are
+gone.
+
+Yet, in a typical user session, there are a number of X11 clients running
+continuously (e.g. Xsettings daemon, IBus, etc.). Those always-running
+clients will prevent the X11 server from terminating, because the actual
+number of X11 clients will never drop to 0.
+
+Disconnect mode allows the X11 clients themselves to specify that they
+should not be accounted for when checking the remaining clients prior
+to terminate the X11 server.
+
+This can be particularly useful for Wayland compositors which are able to
+start Xwayland on demand, as this allows Xwayland to terminate automatically
+when the relevant X11 clients have quit.
+
+13.1 Types
+
+	XFixesClientDisconnectFlags
+
+		XFixesClientDisconnectFlagDefault:	    0
+		XFixesClientDisconnectFlagTerminate:	    1 << 0
+
+	XFixesClientDisconnectFlagDefault is the default behavior for
+	regular clients, i.e. the X11 server won't terminate as long as such
+	clients are still connected.
+
+	XFixesClientDisconnectFlagTerminate indicates to the X11 server that
+	it can ignore the client and terminate itself even though the client
+	is still connected to the X11 server.
+
+13.2 Requests
+
+SetClientDisconnectMode
+
+		disconnect-mode:	    CARD32
+
+	Sets the disconnect mode for the client.
+
+	The disconnect-mode is a bit mask of XFixesClientDisconnectFlags.
+
+
+GetClientDisconnectMode
+
+	Gets the disconnect mode for the client.
+
+		->
+
+		disconnect-mode:	    CARD32
+
+	The disconnect-mode is a bit mask of XFixesClientDisconnectFlags.
