xwm would not let X clients change the focus behind the compositor's
back, reverting focus where it's supposed to be when this occurs.
However, X11 grab also issue focus in events, on which some clients
rely and reverting focus in this case braks the client logic (e.g.
combobox menu in gtk+ using the X11 backend).
Check if the focus event is actually coming from a grab or ungrab and
do not revert focus in this case, to avoid breaking clients logic.

This patch uses the new feature proposed for Xwayland in the patch
series https://patchwork.freedesktop.org/series/16610/ .
When the frame window is created, immediately forbid Xwayland commits on
it. This prevents commits before the decorations have been drawn and the
initial pending state has been set. Commits are enabled right after
drawing and setting.
This ensures that the decorations are fully drawn when a window is
mapped. This also solves the initial commit/pending race, but the race
is on again after mapping.
If Xwayland does not implement the needed support, we are just setting a
window property with no effect.
This patch is the final piece for solving T7622, excluding the
_NET_WM_SYNC_REQUEST handling.

Normal windows enter the MapRequest handler, which schedules drawing the
decorations. Then Xwayland realizes the window, which ends with a call
to xserver_map_shell_surface(). The decorations are already drawn, no
need to draw them a second time. However, MapRequest handler could not
set the pending state because the weston_surface did not exist at the
time, because it gets created only when Xwayland realizes the window,
which happens after XWM has forwarded the MapWindow in MapRequest
handler. Therefore set the pending state explicitly at the end.
Scheduling had it done much later anyway.
Now that the pending state is set much earlier, it seems to be more
likely that it gets set before Xwayland's first commit is handled. This
means that -geometry command line option of X11 apps already takes the
geometry (decorations) into account. I do not think it is reliable yet,
though.
There is still the race between Xwayland committing and XWM setting the
pending state assuming the very next commit latches it in appropriately.
The race exists not because of Wayland, but because WL_SURFACE_ID comes
via X11, and could be processed after wl_compositor.create_surface and
wl_surface.commit. That commit/pending race is solved by a following patch.
For override-redirect windows weston_wm_window_schedule_repaint()
reduced into a call to weston_wm_window_set_pending_state_OR(), so we
can just call that directly. It should not matter that the call is moved
to the end of the function.

Having it in a separate function makes it more clear what it is, and
allows it to be called from elsewhere.
This really is the set_pending_state() alternative for override-redirect
windows, because OR windows do not get a frame window created. Also OR
windows will never hit the normal set_pending_state() because
weston_wm_window_schedule_repaint() special-cased windows without a
frame window and returned early without scheduling.

Split the function into two:
- weston_wm_window_draw_decoration() that only draws the decorations
with Cairo, and
- weston_wm_window_set_pending_state() which sets up the surface state
to be latches into use on the next commit from Xwayland.
The new weston_wm_window_do_repaint() is the equivalent of the old
weston_wm_window_draw_decorations(), everything still happens the same
way as it was. Just some debug messages have been reworded.
weston_wm_window_read_properties() is moved into
weston_wm_window_do_repaint() because it is not strictly a part of
drawing decorations. The same with resetting repaint_source.
draw_decorations does not need the child position nor xwayland
interface. Also some convenience variables have been eliminated.
set_pending_state code has been un-indented by one level, so the change
is best viewed with whitespace changes ignored.
This patch makes the code more readable, and prepares for calling the
draw_decorations and set_pending_state from different places.

X11 applications expect -geometry command line option to work for
setting the initial window position, but currently this does not work.
During map, detect X11 windows that set an explicit position. This works
by heuristics: if window position is not 0,0 then it is explicitly
positioned. Legacy fullscreen windows are also at 0,0 but these are
detected earlier.
Explicitly store the window position at map request time to detect
client-positioned windows, and use it as the suggested initial position.
weston_wm_window::x and y have been overwritten due to reparenting when
we eventually need the initial position.
This patch requires that the new set_toplevel_with_position() hook is
implemented in the shell.
Note that this patch is about positioning xwayland toplevels, not
override-redirect windows which are already handled.

To reproduce the problem:
- start weston (x11 backend worked, glamor in Xwayland makes no
difference)
- start xterm
- very very slowly move the pointer in the xterm decorations onto or
away from a button
- the moment the decorations are updated, they will appear incomplete,
e.g. completely without buttons and title text
- if you cause just one more pointer motion event, the decorations will
update to completely drawn appearance
Another way to reproduce the problem is to have an xterm and change its
window title. This is easy if you use a shell prompt that updates the
terminal window title. When the title updates, decorations will be
half-drawn until something happens in XWM.
The fix: flush.
Apparently the drawing commands did not get flushed to the X server
until any other X11 action pushed them through.
xcb_flush() is the real fix here. cairo_surface_flush() is added just
for good measure, because documentation indicates it would be better
used, however it was not strictly necessary to fix the problem in my
experiments.

Do not check for window->name == NULL, because frame_set_title() handles

The props array contained offsets to struct members. It is convenient
for writing static const arrays as you only store a constant offset and
compute the pointer later. However, the array was not static to begin
with, the atoms are not build time constants. We can as well just store
the pointer directly in the array.
Entries that did not use the offset had bogus offsets, producing
pointers to arbitrary fields. They are changed to have a NULL pointer.
If the code unintentionally used the pointer, it will now explode rather
than corrupt memory.
Also explain the use of the #defined constants and #undef them when they
get out of scope. This clearly documents that they are just a convenient
hack to avoid lots of special cases in the function.

The legacy fullscreen state needs to be detected at MapRequest time,
because that is when the X11 client has alredy set up the initial window
state.
Doing it at xserver_map_shell_surface() meant that it would be done as a
response to Xwayland creating the wl_surface and XWM receiving the
WL_SURFACE_ID ClientMessage, whichever came later. At that point the X11
client might still be setting things up in theory, though in practice
most of the X11 communication has already happened when
xserver_map_shell_surface() gets called.
The real reason for this is to clean up xserver_map_shell_surface() from
everything that would affect drawing the decorations. This patch is one
part of that clean-up.
The weston_output_weak_ref logic is not put into compositor.h, because
there are no other users for it at this time. We need to protect against
the output going away.
A side-effect of this patch is that saved_width and saved_height will
now get overwritten also for legacy fullscreen windows. Previously, they
were left to zero as far as I could tell.
NOTE: This stops override-redirect legacy fullscreen windows from being
detected as fullscreen. MapRequest processing does not happen for OR
windows. These windows get detected as type XWAYLAND instead.
