Whenever a new surface is created, we have to update the cursor focus,
even if there's no input event. So, we generate one motion event, and
reuse the code to update the proper cursor focus. We need to do this
for all surface roles - toplevels, popups, subsurfaces.

153f37bdf5 (#1145) removed the
wlr_xwayland_is_unamanged function while fixing OR, because it was
belieived that it's supposed to work around the broken OR handling.
This was a misunderstanding. is_unmanaged is (while sort of a hack)
intended to work around inherent differences between "real" X sessions
and our Xwayland/wayland situation.
The main reason it exists is to support applications like rofi and dzen,
while not handing focus to other OR windows (which should *not* be
required).
Traditionally, these applications just grabbed input from X and didn't
need to be focused by any logic in the WM. Which of course doesn't work
in wayland compositors. So we have to give them focus in some way.
Giving *every* OR window focus, breaks other applications that don't
expect focus to change.
A testcase that was pointed out to me where wlr_xwayland_is_unamanged was
breaking things is https://github.com/swaywm/sway/issues/2128 (syncplay,
gitk, gitgui)
Supposedly it broke using keyboard to navigate the menus.
I can't reproduce this with this patch. The popups can be navigated as
long as the parent has focus.
Just install a SIG_IGN handler, which is defined by POSIX.1-2001 to
reap the child.
To test, spawn any process (e.g. GUI application) with a keybinding,
close that process, verify it doesn't show up as a <defunct> zombie in
ps(1) output.
The override_redirect flag can change on configure notify and
on map notify. This adds an event to know when it changes.
This removes wlr_xwayland_surface_is_unmanaged which was wrongly
using the window type to decide whether the view should be
unmanaged.
A similar patch was proposed to Weston, but has never been
merged upstream [1].

The previous naming was based on the input-device capability names from
libinput.
With code that uses the libinput_tablet_tool and mapping into tablet-v2,
this is confusing, so the name is changed to follow the names used in
the protocol.
It's possible that a non-default keyboard grab exists when we are trying
to change focus. For example, say there is an XDG popup when we click on
a different window. This popup's keyboard grab will swallow any
keyboard_notify_enter(), meaning the newly-clicked window won't receive
keyboard input.
So, we cancel any existing grabs in roots_seat_set_focus(). Before this
fix, a window would have been set as active but not receive keyboard
entry.
Fixes#233.
