We have 2 sources (this one in MetaSeatNative, and the one in
MetaBackend) dispatching ClutterEvents to the stage. Make the
MetaSeatNative one exclusively about dispatching the libinput
queue, and leave ClutterEvents to the other.

This will resort to SW rendering if this cursor renderer does not
own the MetaKmsCursorRenderer, so it's pretty much equivalent thus
far, except we may now implement logic to flip the kms cursor renderer
around.

We actually have a set_send_events() vfunc that can enable or disable
devices at the libinput and X11 input driver level, so use that. A
positive side effect is that those layers will leave the device at
a consistent idle state (as opposed to going mute maybe amid user
input).

We are aiming for a split of HW and SW cursor rendering management.
Given the HW plane is a limited resource and the amount of cursor
renderers may be >1 (due to tablets, even though we currently use an
always-software cursor renderer there), it would ideally be able to
switch between renderers.
Being MetaCursorRenderer not really a singleton, having cursor
inhibitor accounting here doesn't pan out. Make it MetaBackend API
so all cursor renderers get the same picture.

These use now more of a "pull" model, where they receive update
notifications and the relevant input position is queried, instead
of the coordinates being passed along.
This allows to treat cursor renderers all the same independently
of the device they track. This notifying of position changes should
ideally be more backend-y than core-y, a better location will be
figured out in future commits.

Instead of letting the wayland bits maintain an always-software
cursor renderer, let the cursor renderer be managed by the backend,
and only hook to it (as we do for pointer cursor) in the wayland
bits.
ATM, make the cursor renderer still always-software, although
ideally we should allow moving the HW cursor management between
renderers.

Different devices may get standalone cursor renderers, add this API
to adapt slowly to this. The meta_backend_get_cursor_renderer() call
still exists, but shortcuts to the mouse pointer's renderer (as it
actually did before).

Use a new set in MetaInputDeviceNative, this coexists with
ClutterInputDevice coords for the time being. This API will
eventually be only accessed from the input thread.

While multiple built-in panels isn't actually supported in any
meaningful manner, if we would ever end up with such a situation, e.g.
due to kernel bugs[0], we shouldn't crash when trying to set an
'external only' without any external monitors.
While we could handle this with more degraded functionality (e.g. don't
support the 'switch' method of monitor configuration at all), handle it
by simply not trying to switch to external-only when there are no,
according to the kernel, external monitors available. This would e.g.
still allow betwene 'mirror-all', and 'linear' switches.
The crash itself was disguised as an arbitrary X11 BadValue error, due
to mutter trying to resize the root window to 0x0, as the monitor
configuration that was applied consisted of zero logical monitors, thus
was effectively empty.

xkb recently gained support for user-specified keymaps, which means we
can no longer assume that the configuration data is necessarily fully
complete or correct; and the configuration language is quite a labyrinth,
so it's easy to get wrong. If setting the keymap fails, leave it in
whatever state it previously had, since that seems preferable to crashing
with a NULL pointer dereference.

In case we only have a single view (or there's only one view left to
check and the actor is visible on previous views) we can take a short-
cut, saving a region allocation and some calculations.
While on it, declare float numbers in '.f' style to make them more
recognizable.

Commit 03c69ed8 ("Do not go past size hints on resize") was meant to
ensure the size hints set by the client would be honored during resize,
as going past those values could cause the window to move on resize.
However, it did so by calling ensure_size_hints_satisfied() which works
with the frame rect rather than the client rect. As a result, the
minimum size enforced would end up being larger than expected with
client-side decorations.
Use meta_window_maybe_apply_size_hints() instead which automatically
adjusts for client size.

Since we schedule frames for each stage view seperately now, surfaces receive
frame callbacks for each stage view they are visible on.
Only emit frame callbacks for the primary stage view.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1468>
Our main use case of `is_obscured()` is frame callback emission.
Since we now support stage views running at differt speeds, we
need to know whether an actor is visible on a specific stage view
in order to schedule frame callbacks accordingly.

Commit e28c1ab4 added a hints_have_changed() function to only
recalculate windows features when the WM_NORMAL_HINTS change.
That function hints_have_changed() however was merely checking whether
the various XSizeHints flags where flipped, which is not sufficient
because the hints may remain the same while the actual values are
changed.
Not checking for the actual value differences would prevent some windows
from being able to switch fullscreen.
Improve the helper function hints_have_changed() to check not only for
flags being flipped, but also for the values being changed for each
relevant XSizeHints flags being set currently.

Sometimes the automatically selected primary GPU isn't suitable with no
way to make an well educated guess to do it better. To make it possible
for the user to override the automatically calculated default, make it
possible to override it using a udev rule.
E.g. to select /dev/dri/card1 as the primary GPU, add a file e.g.
/usr/lib/udev/rules.d/61-mutter-primary-gpu.rules (path my vary
depending on distribution) containing the fellowing line:
ENV{DEVNAME}=="/dev/dri/card1", TAG+="mutter-device-preferred-primary"
Reboot or manual triggering of udev rules to make it take effect may be
required.

Instead of aborting with an error, display a half transparent gray
square instead of cursors and log a warning in the journal, allowing the
user to fix their system withotu having to rely on switching to a TTY.
It will be immediately obvious the cursor is silly looking, which will
be a better hint than just aborting.
