This is a work in progress that builds Xvfb, Xephyr, Xwayland, Xnest,
and Xdmx so far. The outline of Xquartz/Xwin support is in tree, but
hasn't been built yet. The unit tests are also not done.
The intent is to build this as a complete replacement for the
autotools system, then eventually replace autotools. meson is faster
to generate the build, faster to run the bulid, shorter to write the
build files in, and less error-prone than autotools.
v2: Fix indentation nits, move version declaration to project(), use
existing meson_options for version-config.h's vendor name/web.

Despite all the careful planning of the kernel, a link may become
insufficient to handle the currently-set mode. At this point, the
kernel should mark this particular configuration as being broken
and potentially prune the mode before setting the offending connector's
link-status to BAD and send the userspace a hotplug event. This may
happen right after a modeset or later on.
Upon receiving a hot-plug event, we iterate through the connectors to
re-apply the currently-set mode on all the connectors that have a
link-status property set to BAD. The kernel may be able to get the
link to work by dropping to using a lower link bpp (with the same
display bpp). However, the modeset may fail if the kernel has pruned
the mode, so to make users aware of this problem a warning is outputed
in the logs to warn about having a potentially-black display.
This patch does not modify the current behaviour of always propagating
the events to the randr clients. This allows desktop environments to
re-probe the connectors and select a new resolution based on the new
(currated) mode list if a mode disapeared. This behaviour is expected in
order to pass the Display Port compliance tests.

The X11 window manager (XWM) of a Wayland compositor can use the
_XWAYLAND_ALLOW_COMMITS property to control when Xwayland sends
wl_surface.commit requests. If the property is not set, the behaviour
remains what it was.
XWM uses the property to inhibit commits until the window is ready to be
shown. This gives XWM time to set up the window decorations and internal
state before Xwayland does the first commit. XWM can use this to ensure
the first commit carries fully drawn decorations and the window
management state is correct when the window becomes visible.
Setting the property to zero inhibits further commits, and setting it to
non-zero allows commits. Deleting the property allows commits.
When the property is changed from zero to non-zero, there will be a
commit on next block_handler() call provided that some damage has been
recorded.
Without this patch (i.e. with the old behaviour) Xwayland can and will
commit the surface very soon as the application window has been realized
and drawn into. This races with XWM and may cause visible glitches.
v3:
- introduced a simple setter for xwl_window::allow_commits
- split xwl_window_property_allow_commits() out of
xwl_property_callback()
- check MakeAtom(_XWAYLAND_ALLOW_COMMITS)

- use PropertyStateCallback instead of XACE, based on the patch
"xwayland: Track per-window support for netwm frame sync" by

- check property type is XA_CARDINAL
- drop a useless memcpy()
