Launching pipewire and wireplumber is racy, as there is an arbitrary
amount of time between pipewire is launched, and that the socket is
bound.
In order to eliminate this race, bind the pipewire sockets ourselves,
and launch pipewire (and wireplumber) when there is activity on the
socket. This is using the systemd method of doing socket activation,
which consists of passing the number of passed file descriptors via
$LISTEN_FDS, and the pid of the launchee via $LISTEN_PID.
The former is easy, just pass the file descriptors, but the former is
more tricky when using python, as executing code before exec() is poorly
supported and likely to be deprecated. To address this, socket
activation services are wrapped in a socket-launch.sh helper which sets
the $LISTEN_PID to itself before calling exec().

list = ['one']
list.append('two,three'.split(','))
results in ['one', ['two', 'three']]
while
list += 'two,three'.split(',')
results in ['one', 'two', 'three']

While when running with meson, we want the output to be in meson-logs
for convenience, such a path isn't feasible when running as an installed
test. To address this, make the destination path configurable via an
environment variable.

This aims to replace a reoccuring arbitrary sleep followed by a focus
assertion. The problem with these is that the sleep does not reliably
wait for long enough, due to arbitrary system resource usage in CI and
elsewhere. By instead waiting, and instead asserting we don't have any
intermediate wrong focus, we remove the race, and test for more invalid
situations.

If the KMS thread is using the deadline timer, and a valid sync_file
descriptor is passed in:
1. The update is deferred, and the deadline timer is left armed, until
the sync_fd signals (becomes readable).
2. Implicit synchronization is disabled for the KMS update.
This means cursor updates should no longer miss a display refresh
cycle due to mutter's compositing GPU work finishing too late.

If the window_drag->handle ClutterActor:visible property is FALSE,
then we avoid a full-framebuffer damage on the monitor when beginning
and ending a drag.
Testing with `mutter --wayland --display-server` still shows a full-
framebuffer damage on the first drag, but that appears to be unrelated
to this. Subsequent full-framebuffer damage which would occur on
drag-begin and drag-end have been elided.

Toplevels get the main monitor from their MetaWindow and have no main
monitor when the toplevel is not mapped.
Subsurfaces get the main monitor from their parent surface.
DnD and cursors get the main monitor from the current cursor position no
matter if the cursor is actually being shown or not.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3941>
The main monitor is role dependent. For a toplevel this comes from the
MetaWindow main monitor, for a subsurface from the parent surface, for
pointer and dnd from the cursor position.
The next commit will use meta_wayland_surface_set_main_monitor in the
different roles to keep the property up-to-date.

So far, the tests relied on the host system to provide pipewire and
wireplumber. This seperates the tests from the host system which is
especially useful if the tests are run in a toolbox which has a
different pipewire installed than the host. It also should make it
harder to have a mismatch between the pipewire library and the pipewire
daemon.

We're already inhibiting real time scheduling when reading new KMS state
after hot plugs, as well as when during mode sets, due to the kernel not
being able to reliably handle these within the 250 ms limit. However, we
didn't do this during initial probing, which meant that occasionally
we'd run into these kind of issues during startup.
Handle this by always inhibiting real time scheduling up front, and
don't uninhibit until all initially discovered device have finished
processing their initial mode set.

If an application is maximised, clutter_stage_pick_and_update_device()
goes into the
if ((flags & CLUTTER_DEVICE_UPDATE_IGNORE_CACHE) == 0)
condition and returns the current actor for the device. This means no
CLUTTER_LEAVE/ENTER events are generated and in turn means the focus is
never invalidated and updated.
This leads to tool->focus_surface always being NULL and all events are
discarded.
Notably, tool->current is set to the right surface but
that one never changes either so meta_wayland_tablet_tool_set_current_surface()
exits early too because surface == tool->current and we thus never call
meta_wayland_input_invalidate_focus().

Clutter's "device-removed" signal is sent in
clutter_seat_handle_event_post(). Our tablet code is set up to handle
that signal to then notify wayland clients of removed tablet devices.
However, returning CLUTTER_EVENT_STOP for a DEVICE_REMOVED event means
we never get to the point where we send out the signals and thus never
remove the tablets.

Let's add a bunch of tests for the newly introduced monitor config
migration code. We're verifying that:
- monitor configs get migrated and monitors.xml is updated on startup
- existing monitor configs in LOGICAL layout mode (ie.
"scale-monitor-framebuffers" was enabled before updating mutter) get
migrated
- the migration of various more complex monitor layouts from PHYSICAL
to LOGICAL layout mode works
- for monitor layouts where conversion to LOGICAL fails, the PHYSICAL
layout mode still is migrated, while for LOGICAL at least primary
monitor and disabled monitors are preserved
- simple monitor configurations (with no scaled monitors, or with only
"irrelevant" scaled monitors at the end of the layout) do not go through
the conversion code paths
- monitor configs in PHYSICAL layout mode with integer scale factors
which will result in non-integer logical monitor sizes get converted
to the closest fractional scale factor
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3596>
We don't want to do the work of the layout mode detection and conversion
every time we read the monitors.xml file.
Instead, when the detection logic is used, set a flag to automatically
update the config files after the parsing is finished.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3596>
Introduce some "best effort" conversion code to migrate monitor configurations
from PHYSICAL (the old default) to LOGICAL (the new default on wayland)
layout mode.
This conversion will only be used when the old PHYSICAL layout-mode
configuration is not compatible with the new LOGICAL layout-mode one.
This only applies if 1) there's a monitor that needs scaling in the
layout, and 2) the scaled monitor comes before other monitors in the
coordinate system (ie. it's not the rightmost or bottommost monitor).
There are two algorithms added here to convert monitor layouts:
- One for "simple" 1-dimensional monitor layouts, where all monitors are
aligned on a vertical or horizontal strip.
Here's a few (inaccurate) examples of how this would look with different
layouts (left side is PHYSICAL, right side is LOGICAL, x is the origin of
the coordinate system, the numbers are scales of the monitors):
```
x──────┬──────┬──────┐ x ┌──────┐
│ 2 │ 1 │ 2 │ 2┌──┤ 1 ├──┐2
│ │ │ │ ──► └──┤ ├──┘
└──────┴──────┴──────┘ └──────┘
x ┌──────┐ x ┌──────┐
┌────┤ 1 │ ┌──┤ 1 │
│ 2 │ │ ──► └──┤ │
└────┴──────┘ 2 └──────┘
x ┌────┐
┌──────┤ │ x──────┐

│ │ │ │ ├─┴────┘
└──────┤ │ └──────┘
│ ├────┐
│ │ 1 │
└────┴────┘
```
- A second more complex algorithm for 2-dimensional monitor layouts with
a common baseline that all monitors are aligned to.
And examples for this one:
```
x ┌──────┐
┌──────┤ │
│ 1 │ 2 │ x──────┐
│ │ │ │ 1 ├────┐
└──┬───┴───┬──┘ ──► │ │ 2 │
│ 3 │ ├──┬───┴────┘
│ │ └──┘3
└───────┘
x ┌──────┬──────┐
│ 1 │ │
│ │ │ x──────┬──────┐
┌─────┴──────┤ 1 │ │ 1 │ │

│ │ ├──┴┬─────┴───────┘
│ 2 │ │ 2 │
│ │ └───┘
└────────┘
```
These algorithms will fail for any more complex 2d monitor layout, eg.
```
x ┌───┬────┐
│ 2 │ 1 │
│ ├────┘
┌───┴┬──┘
│ 1 │
└────┘
x───┬───┬───┐
│ 1 │ 2 │ 1 │
├───┼───┼───┤
│ 1 │ 1 │ 1 │
├───┼───┼───┤
│ 1 │ 1 │ 1 │
└───┴───┴───┘
```
In those cases where the conversion failed, we fall back to aligning
the monitors on a horizontal line, preserving the scale, the primary
monitor and the disabled monitors.
Note that we also need to convert the scale factor in some cases,
because LOGICAL layout mode also behaves different here:
When the scale results in a fractional logical monitor size (eg.
the native monitor width is 2560px, and a scale of 3 is set =>
2560px / 3 = 853.333px), in LOGICAL mode we won't use that scale.
Instead we have an algorithm (see
meta_monitor_get_closest_scale_factor_for_resolution()) to find
the nearest fractional scale factor which doesn't result in
fractional logical monitor size. We reuse this algorithm here for
the conversion.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3596>
We'll reuse meta_monitor_get_closest_scale_factor_for_resolution() for the
conversion of monitor configs, and during those conversions, we probably don't
want to impose the same limits to fractional scales that we usually impose.
This means that we can even convert physical layout configs where the user
manually changed to a value higher than what our fractional scale calculations
would allow.
Move this check into the calling function so that it's not imposed by
meta_monitor_get_closest_scale_factor_for_resolution() directly.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3596>
When there is no layout mode set in a logical monitor config, we currently just
assume the configuration matches the mode that the system expects. This blows
up when the layout mode expected by the system changes (eg. by turning on
"scale-monitor-framebuffers" in mutter): Suddenly configs fail the validation
check and get thrown away.
Since we now can add one configuration for each layout mode to the config store,
we can do better here: Let's only add configurations to the store where we
verified beforehand that the monitor layout is compatible with that mode, either
because we set it ourselves using the <layout_mode> key, or by detecting which
modes the layout is compatible with.
Also update monitor config ifiles to adjust for the new layout_mode, as
they all are assumed to be "logical".
