Many tablets have a native portrait mode panel, yet come with a keyboard dock,
where the device gets docked in landscape mode. To avoid the display being
on its side when mutter starts while the tablet is docked, we need to take
the accelerometer reported orientation into account even if there is a
tablet-mode-switch which indicates that the device is NOT in tablet-mode
(because it is docked).
Add special handling for the first time the "orientation-changed"
signal gets signalled by the orientation-manager, which happens after it
has successfully claimed the accelerometer with iio-sensor-proxy.
The added special handling of the initial "orientation-changed" signal
does a number of checks:
1. panel_orientation_managed is false because of the tablet-mode-switch and not
because of other reasons.
2. The device has a native portrait mode panel (and thus likely needs rotation
to display the image the right way up when docked).
If all these checks succeed then it continues with creating a new
monitors-config based on the orientation ignoring the panel_orientation_managed
value (for the initial/first "orientation-changed" signal only).
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1506
The orientation reported by the orientation_manager may have changed while
panel_orientation_managed was false. So when panel_orientation_managed
changes to true we should re-check the orientation.
This fixes the orientation not being correct when e.g. taking a 360 degree
hinges 2-in-1 in clamshell mode (so landscape orientation) and then folding
it into tablet mode while holding it in portrait orientation.

We only want the panel autorotation to happen if the laptop has an
accelerometer, and is in tablet mode. Regular laptop mode should
lock the orientation, and let it be configured manually.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1311
So far, we've expected this signal to not happen whenever autorotation
shouldn't apply (no accelerometer is a strong reason). In future commits
we'll add further checks to this policy, so prevent autorotation to
change the display configuration if the MetaOrientationManager signal
happens but it should be ignored.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1311
Instead of having everyone check net.hadess.SensorProxy themselves, have
this all controlled by the MetaOrientationManager, and proxied everywhere
else via a readonly property in org.gnome.Mutter.DisplayConfig.
We want to attach more complex policies here, and it seems better to
centralize the handling of the autorotation feature rather than
implementing policy changes all over the place.

The ID and name are just moved into the instance private, while the rest
is moved to a `MetaCrtcModeInfo` struct which is used during
construction and retrieved via a getter. Opens up the possibility to
add actual sub types.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1287
Now set as a property during construction. Only actually set by the
Xrandr backend, as it's the only one currently not supporting all
transforms, which is the default.
While at it, move the 'ALL_TRANFORMS' macro to meta-monitor-tranforms.h.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1287
The output info is established during construction and will stay the
same for the lifetime of the MetaOutput object. Moving it out of the
main struct enables us to eventually clean up the MetaOutput type
inheritence to use proper GObject types.

That is is_presentation, is_primary, is_underscanning and backlight.
The first three are set during CRTC assignment as they are only valid
when active. The other is set separately, as it is untied to
monitor configuration.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1287
To make it more reliable to distinguish between values that are read
from the backend implementation (which is likely to be irrelevant for
anything but the backend implementation), split out those values (e.g.
layout).
This changes the meaning of what was MetaCrtc::rect, to a
MetaCrtcConfig::layout which is the layout the CRTC has in the global
coordinate space.

This is inspired by 98892391d7 where the usage of
`g_signal_handler_disconnect()` without resetting the corresponding
handler id later resulted in a bug. Using `g_clear_signal_handler()`
makes sure we avoid similar bugs and is almost always the better
alternative. We use it for new code, let's clean up the old code to
also use it.
A further benefit is that it can get called even if the passed id is
0, allowing us to remove a lot of now unnessecary checks, and the fact
that `g_clear_signal_handler()` checks for the right type size, forcing us
to clean up all places where we used `guint` instead of `gulong`.
No functional changes intended here and all changes should be trivial,
thus bundled in one big commit.

Instead of doing a roundtrip to the X server before setting it, rely on
the previous value fetched before the configuration was sent over DBus.
This matches the argument check we already do elsewhere, and will allow
us to more easily add an additional condition to determine if underscan
is supported.

Since 4cae9b5b11, and indirectly before that as well, the
MetaMonitorManager::power-save-mode-changed is emitted even
when the power save mode didn't actually change.
On Wayland, this causes a mode set and therefore a stuttering.
It became more proeminent with the transactional KMS code.
Only emit 'power-save-mode-changed' when the power save mode
actually changed.

The display name is being used by the monitor manager to expose to name
to the DBUS API.
It is being rebuilt each time, so instead build the displa yname once
for the monitor and keep it around, with an API to retrieve it, so that
we can reuse it in preparation of xdg-output v2 support.

DPMS is configured from a bit all over the place: via D-Bus, via X11 and
when reading the current KMS state. Each of these places did it slightly
differently, directly poking at the field in MetaMonitorManager.
To make things a bit more managable, move the field into a new
MetaMonitorManagerPrivate, and add helpers to get and set the current
value. Prior to this, there were for example situations where the DPMS
setting was changed, but without signal listeners being notified about
it.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/506
Commit 25f416c13d added additional compilation warnings, including
-Werror=return-type. There are several places where this results
in build failures if `g_assert_not_reached()` is disabled at compile
time and the compiler misses a return value.

MonitorManager was inheriting from MetaDBusDisplayConfigSkeleton, this was
causing introspection to see this like a GDBus skeleton object exposing to
clients methods that were not required.
Also, this required us to export meta_dbus_* symbols to the library, while
these should be actually private.
So, make MetaMonitorManager to be just a simple GObject holding a skeleton
instance, and connect to its signals reusing most of the code with just few
minor changes.

Switch-configs are only to be used in certain circumstances (see
meta_monitor_manager_can_switch_config()) so when ensuring
configuration and attempting to create a linear configuration, use the
linear configuration constructor function directly without going via the
switch config method, otherwise we might incorrectly fall back to the
fallback configuration (only enable primary monitor).
This is a regression introduced by 6267732bec.

It wasn't implemented by any subclass, it's not provided by DRM either.
And even if a subclass were to have only a file available, it could read
it into a GBytes as well and just use `read_edid()`.
Found this while working on !269.
The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
When constructing MetaMonitorsConfig objects, store which type
of switch_config they are for (or UNKNOWN if it is not such
type of config).
Stop unconditionally setting current_switch_config to UNKNOWN when
handling monitors changed events. Instead, set it to the switch_config
type stored in the MonitorsConfig in the codepath that updates logical
state. In addition to being called in the hotplug case along the same
code flow that generates monitors changed events, this is also called
in the coldplug case where a secondary monitor was connected before
mutter was started.
When creating the default linear display config, create it as a
switch_config so that internal state gets updated to represent
linear mode when this config is used.
The previous behaviour of unconditionally resetting current_switch_config
to UNKNOWN was breaking the internal state machine for display config
switching, causing misbehaviour in gnome-shell's switchMonitor UI when
using display switch hotkeys. The lack of internal tracking when the
displays are already in the default "Join Displays" linear mode was
then causing the first display switch hotkey press to do nothing
(it would attempt to select "Join Displays" mode, but that was already
active).

Avoid exporting through org.gnome.Mutter.DisplayConfig.GetCurrentState
excessively-low screen resolutions setting both a minimum width and a minimum
height. GetCurrentState is e.g. used by Gnome Control Center to build a list of
selectable resolutions.

Rather than handle UpClient in both MetaBackend (to reset the idletime
when the lid is opened), and in MetaMonitorManager and
MetaMonitorConfigManager (to turn the screen under the lid on/off
depending on its status), move the ability to get the lid status from
UPower or mock it in one place, in MetaBackend.
Restarting UPower will make every property of UpClient emit a "notify"
signal (as a GDBusProxy would). Avoid mutter reconfiguring the displays
when upower restarts by caching the last known value of "lid-is-closed"
and only reconfiguring the displays if it actually changed.
This fixes a black out of the screen when UPower restarts.
