This makes it possible to pass custom properties to backends when
constructing tests. This will be used to create "headless" native
backend instances for testing the headless native backend.

With this commit, it's possible to run mutter without being DRM master.
It's not yet possible to add virtual monitors, but one can for example
already add virtual input devices.
This currently doesn't try to hook up to any logind session, thus will
not have a real seat assigned. Currently it's hard coded to "seat0".

Currently our only entry point for DRM devices is MetaKms*, but in order
to run without being DRM master, we cannot use /dev/dri/card*, nor can
we be either of the existing MetaKmsImplDevice implementation (legacy
KMS, and atomic KMS), as they both depend on being DRM master.
Thus to handle running without being DRM master (i.e. headless), add a
"dummy" MetaKmsImplDevice implementation, that doesn't do any mode
setting at all, and that switches to operate on the render node, instead
of the card node itself.
This means we still use the same GBM code paths as the regular native
backend paths, except we never make use of any CRTC backed onscreen
framebuffers.
Eventually, this "dummy" MetaKmsImplDevice will be replaced separating
"KMS" device objects from "render" device objects, but that will require
more significant changes. It will, however, be necessary for e.g. going
from being headless, only having access to a render node, to turning
into a real session, with a seat, being DRM master, and having access to
a card node.
This is currently not hooked up, but will be in a later commit.

Add a flag to MetaSeatNative and MetaSeatImpl that tells it not to
attempt to create a libinput context. This is intended to be used when
mutter is to run headless, as in without any input devices other than
virtual ones.
Currently not hooked up.

This leaves only the atomic mode setting cap check before creating the
impl device, aiming to make it possible to create a non-mode-setting
MetaKmsImplDevice implementation.

Make it possible to pass --headless as a command line argument in order
to turn the native backend "headless". This currently doesn't do
anything, but the intention is that it should not use logind nor KMS,
and work completely headless with only virtual outputs.

Input settings requires a valid seat in order to initialize the a11y
settings (since commit 1609d145), however in X11 we never set it and
even if we create the input settings early (as per commit 7547891a) we
never initialize the seat for it.
This leads to startup critical errors on X11:
clutter_seat_get_pointer_a11y_settings: assertion
'CLUTTER_IS_SEAT (seat)' failed

This commit adds the events created in the function
`meta_seat_x11_notify_devices` to the clutter events queue, which
are currently only added to the stage queue making the events not
being picked up by the `clutter_seat_handle_event_post` function.
This results in devices not getting added to the device-list of
`MetaInputSettings`.
Fixes the bug in which mouse and touchpad settings are not working in
the settings app during x11 session.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1767>
Since commit 2ceac4a device-related X11 events aren't processed anymore,
causing the input settings not to handle the devices.
This is due to the fact that we may never call clutter_seat_handle_event_post()
for such events.
While this is always happening for the native backend, it doesn't happen in
X11 because the events are removed from the queue as part of
meta_x11_handle_event(), and thus no event was queued to the stage by the
backend events source.
This also makes sure that the event post handler is called after the
event is actually processed, and not before an event is queued.

The nested backend may need to have an input setting implementation,
while we don't want to change the host settings (re-using an X11 input
settings) we can add a dummy implementation, until something more
complex is needed.

The sync ring has an API about "frames", where it is notified about
the end of frames. However, its "insert wait" call is done before
updates, meaning that some "insert waits" will never see the "after
frame" if there was no frame drawn. This will cause mismatching in the
frame counting, causing freezes in the synchronization until something
else triggers an actual frame, effectively "unfreezing" the sync ring.
Fix this by not only notifying the sync ring about frames when there
were actual frames drawn, but also on plain updates which didn't result
in a drawn frame.

When a gtk theme uses larger shadows for the unfocused state than for
the focused one, this can cause a crash in meta_frame_left_click_event.
Since whether to call meta_frame_left_click_event is decided based on
the decoration size before focusing and the control that was clicked on
after focusing, this can result in an event handled in
meta_frame_left_click_event being on the client area.

With commit 7d78768809 we switched to
storing pointer coordinates in MetaInputDeviceNative instead of
ClutterInputDevice, and while we had set the coordinates of the
ClutterInputDevice in ClutterStage when queueing an event, we now set
the MetaInputDeviceNative coordinates in new_absolute_motion_event().
Here a small mistake snuck in: new_absolute_motion_event() only
translates the coordinates of the event, but we call
meta_input_device_native_set_coords() using the x and y variables
(which remain untranslated), so now the input device coordinates are no
longer translated.
Fix that by translating the coordinates of the x and y variables in case
we're we handling a tablet/stylus event instead of only translating the
event coordinates.

This fixes the interpolate test to not use the wall clock, but the
monotonic clock. It also cleans up the timestamp granularity naming, so
that the different granularity is clearer, as in the test, different
timestamps have different granularity.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1751>
This more or less rewrites this test so that it explicitly tests the
"interpolation" when a timeline loops, i.e. that if something occupies
the thread when a timeline was supposed to have looped, we end up in the
right place "in the middle" of the next timeline cycle.
The test more or less does this:
* Start a 3 second looping timeline
* Sleep so that we're in the middle of the first cycle
* Sleep again so that we end up in the middle of the next cycle
The semantics checked are that we see the following frames:
* The first frame with timestamp 0
* The second frame in the middle of the first cycle (timestamp ~= 1.5
sceonds)
* The third frame in the end of the first cycle (timestamp == 3.0
seconds)
* The fourth frame, first in the second cycle, with timestamp ~= 1.5
seconds)
This means we can increase the "grace period" to the double (from 0.5 s
to 1 s), while at the same time decrease the time spent running the test
(from 10 s to 4.5 s). This should hopefully make the test less flaky,
especially in slower runners, e.g. aarch64.

With commit c985753442 the support for
multiple hardware cursors broke, but those were never properly supported
anyway as we usually assume there's only one hardware cursor around.
With the introduction of the KMS thread in the future, we'll only have
one KMS cursor that gets updated directly from the input thread. So
apart from the fact that it never really makes sense to have two cursors
visible, in this new model having multiple cursors won't work anyway.
So make the cursor we show for stylii a software cursor again.
Eventually the plan is to make the input device that's driving the KMS
cursor interchangeable, so that we can always use hardware cursors.
This reverts commit 165b7369c8.

This commit assumes that cursor surfaces work in a "mailbox" fashion. If
they are painted multiple times before a successful flip, all commits
but the last get discarded, and the last commit gets presented after the
flip succeeds. This is more or less how it works in the atomic backend,
and also more or less how it works in other backends, with the exception
that the cursor painting might fail without any way of knowing. This
assumption is still better than unconditionally discarding all cursor
surface feedbacks as if the cursor painting always fails.

Regarding the sequence = 0 fallback: in some cases (moving a cursor
plane on atomic amdgpu) we get sequence = 0 in the page flip callback.
This seems like an amdgpu bug, so work around it by assuming a sequence
delta of 1 (it is equal to 1 because of the sequence != 0 check above).
Sequence can also legitimately be 0 if we're lucky during the 32-bit
overflow, in which case assuming a delta of 1 will give more or less
reasonable values on this and next presentation, after which it'll be
back to normal.
Sequence is also 0 on mode set fallback and when running nested, in
which case assuming a delta of 1 every frame is the best we can do.

The presentation-time protocol allows surfaces to get accurate
timestamps of when their contents were shown on screen.
This commit implements a stub version of the protocol which correctly
discards all presentation feedback objects (as if the surface contents
are never shown on screen). Subsequent commits will implement sending
the presented events to surfaces shown on screen.

This concerns only the cases when the presentation timestamp is received
directly from the device (from KMS or from GLX). In the majority of
cases this timestamp is already MONOTONIC. When it isn't, after this
commit, the current value of the MONOTONIC clock is sampled instead.
The alternative is to store the clock id alongside the timestamp, with
possible values of MONOTONIC, REALTIME (from KMS) and GETTIMEOFDAY (from
GLX; this might be the same as REALTIME, I'm not sure), and then
"convert" the timestamp to MONOTONIC when needed. An example of such a
conversion was done in compositor.c (removed in this commit). It would
also be needed for the presentation-time Wayland protocol. However, it
seems that the vast majority of up-to-date systems are using MONOTONIC
anyway, making this effort not justified.

KMS and GLX device timestamps have microsecond precision, and whenever
we sample the time ourselves it's not the real presentation time anyway,
so nanosecond precision for that case is unnecessary.
The presentation timestamp in ClutterFrameInfo is in microseconds, too,
so this commit makes them have the same precision.

This is definitely the case for page_flip_handler(), and I'm assuming
this is also the case for the two instances in the GLX code.
