When using gtk under X11 some WM related events are always filtered and not
delivered when using the gdk Window filters.
So, add a new one with higher priority than the GTK events one so that we can
pick those events before than Gtk itself.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/669
Allow to set/unset WM_TAKE_FOCUS from client window.
This is added by default by gtk, but this might not happen in other toolkits,
so add an ability to (un)set this.
So fetch the protocols with XGetWMProtocols and unset the atom.
test-client now needs to depend on Xlib directly in meson build.

The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
Add a "set_parent_exported" command to test the xdg-foreign support, so
that we can add a test which uses the GDK API for exported window:
`gdk_wayland_window_set_transient_for_exported()`
That will allow to detect if transient is applied correctly between
foreign windows and detect possible crashes such as issue !174.

Previously we relied on the test-client to make sure that a window was
shown. For X11, we did not need to do anything, but for Wayland we had
to make sure we had drawn the first frame, otherwise mutter wouldn't
have a buffer making the window not showable.
Doing it this way doesn't work anymore however, since the 'after-paint'
event will be emitted even if we didn't actually paint anything. This is
the case with current Gtk under Wayland, where we won't draw until the
compositor has configured the surface. In effect, this mean we'll get a
dummy after-paint emission before the first frame is actually painted.
Instead, move the verification that a "show" command has completed by
having the test-runner wait for a "shown" signal on the window, which is
emitted in the end of meta_window_show(). This requires an additional
call to gdk_display_sync() in the test-client after creating the window,
to make sure that the window creation vents has been received in the
compositor.
The test runner sends a "show" command to the test clients and assumes
this was enough work done by the client to enable the compositor to map
the window. Now that we wait to show a Wayland window until the first
buffer is attached (see bug 750552), we need to make sure that we attach
a buffer before assuming that we have the final stacking order.
So, to in order to continue relying on "show" to be enough to actually
show a window, let the test client wait until it has drawn the first
frame.
This makes the tests using Wayland clients test non-flaky.

Add commands to request the client to minimize or unminimize the window;
unminimize doesn't currently work for GTK+ because it expects XMapRequest
to be received by the window manager, but the window is already mapped.

Add a basic framework for tests of Mutter handling of client behavior;
mutter-test-runner is a Mutter-based compositor that forks off instances
of mutter-test-client and sends commands to them based on scripts.
The scripts also include assertions.
mutter-test-runner always runs in nested-Wayland mode since the separate
copy of Xwayland is helpful in giving a reliably clean X server to
test against.
Initially the commands and assertions are designed to test the stacking
behavior of Mutter, but the framework should be extensible to test other
parts of client behavior like focus.
The tests are installed according to:
https://wiki.gnome.org/Initiatives/GnomeGoals/InstalledTests
if --enable-installed-tests is passed to configure. You can run them
uninstalled with:
cd src && make run-tests
(Not in 'make check' to avoid breaking 'make distcheck' if Mutter can't be
run nested.)
