Modify create_for_builtin_display_rotation to lookup the
MetaLogicalMonitorConfig for the panel in the logical_monitor_configs
list instead of only working when there is only 1 monitor.
The goal of this change is to honor accelerometer value changes when there is
more than 1 monitor.
Note, since create_for_builtin_display_rotation is also used for handling the
"rotate-monitor" hotkey and this commit modifies the common path of
create_for_builtin_display_rotation this means that we will now also honor
"rotate-monitor" hotkey keypresses when there is more than 1 monitor and
update the builtin display rotation instead of ignoring "rotate-monitor"
hotkey keypresses when there is more than 1 monitor. If this is deemed
undesirable this is easy to fix, but I believe that doing things this way
is more consistent.

Add a clone_logical_monitor_config_list helper function for making a deep
copy of MetaLogicalMonitorConfig lists.
This is a preparation patch for honoring accelerometer value changes when
there is more than 1 monitor.

When creating a new config because of a monitor being (un)plugged or
because of super+p being pressed, honor the orientation reported by
the accelerometer for the internal panel.
Before this commit we would always configure the internal panel with
a normal / upright transform when e.g. an external monitor gets plugged
in even if another transform was in use before plugging in the external
monitor. This is inconsistent and causes problems for several use-cases.
This commit fixes this by querying the accelerometer when creating a new
config for an internal panel.

Bail out of sync_state() immediately if the orientation is locked, before
calling read_iio_prox() which updates the curr_orientation value.
There are 2 reasons for this change:
1. Currently meta-monitor-config-manager.c always assumes normal / upright
orientation when generating a new config. This means that e.g. when an
external monitor gets plugged in the builtin panel's transform will be reset
to normal / upright even if the device is not in an upright orientation.
To fix this meta-monitor-config-manager.c needs to call
meta_orientation_manager_get_orientation() to get the current orientation
when generating a new config. Without this change locking the orientation
would stop the emitting of "orientation-changed" signals but we would
still update the curr_orientation value. So when a new config needs to
be generated the latest orientation would be used, effectively ignoring
the "orientation-lock" setting, not updating curr_orientation when
locked fixes this.
2. This ensures we properly emit an an "orientation-changed" signal when
the orientation has changed between when it was locked and it was
unlocked. Before this change if the user locked the orientation, changed it
and then unlocked it, no signal would be raised as we would already have
updated the curr_orientation value turning the sync_state() call in
orientation_lock_changed() into a no-op.

When creating a virtual device for the native backend, no "device-added"
is emitted.
Similarly, no "device-removed" signal is emitted either when the virtual
device is disposed.
However, the backend plugs into the "device-added" signal to set the
monitor device. Without the "device-added" signal being emitted, the
monitor associated with a virtual device remains NULL.
That later will cause a crash in `meta_idle_monitor_reset_idlettime()`
called from `handle_idletime_for_event()` when processing events from a
virtual device because the device monitor is NULL.
Make sure to emit the "device-added" signal when creating a virtual
device, and the "device-removed" when the virtual device is disposed.

The devices_by_id hash table is responsible for managing the reference
to the devices. In remove_device however, for non-core devices there are
additional calls to dispose/unref, after the last reference has
already been dropped by the hash table.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1032
e9fbbd5853 changed meta_backend_get_idle_monitor() to use
ClutterInputDevice pointers instead of device IDs, but did not adjust
the call in meta_backend_native_resume() which was still using 0 to get
the core idle monitor resulting in a NULL pointer dereference.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1029
The meta_seat_native_constrain_pointer() function receives the current
pointer position, and the new pointer position as in/out parameters.
We were however calculating the new coordinates based on the last pointer
position if there was no pointer constrain in place.
Fortunately to us, this didn't use to happen often/ever, as a pointer
constrain function is set on MetaBackend initialization. This behavior
did also exist previously in MetaDeviceManagerNative.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1028
The backend being initialized triggers a pointer warp (and motion event)
where we want to observe the callbacks put in place. So ensure we set
up the hooks before that could happen.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/852
Just go ATM through backend checks, and looking up directly the
native event data, pretty much like the rest of the places do that...
Eventually would be nice to have this information in ClutterEvent,
but let's not have it clutter the MetaBackend class.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/852
This is unlikely to happen, and unlikely to be right (eg. we don't translate
input event coordinates, since those are not in display coordinate space, we
don't offer any feedback for those either).
This can simply be dropped, we listen to XIAllMasterDevices, which suffices
for what we want to do.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/852
The gamma value pointers of the current_state are overwritten by the
calls to memdup causing a small leak. while the leak itself is small, it
can be triggered quite often from things like night light.

Where possible, try to export the buffer rendered by the primary GPU as a
dmabuf and import it to the secondary GPU and turn it into a DRM FB for
scanout. If this works, we get a zero-copy path to secondary GPU outputs.
This is especially useful on virtual drivers like EVDI (used for DisplayLink
devices) which are not picky at all about what kind of FBs they can handle.
The zero-copy path is prioritised after the secondary GPU copy path, which
should avoid regressions for existing working systems. Attempting zero-copy
would have the risk of being less performant than doing the copy on the
secondary GPU. This does not affect the DisplayLink use case, because there is
no GPU in a DisplayLink device.
The zero-copy path is prioritised before the primary GPU and CPU copy paths. It
will be tried on the first frame of an output and the copy path is executed
too. If zero-copy fails, the result from the copy path will take over on that
frame. Furthermore, zero-copy will not be attemped again on that output. If
zero-copy succeeds, the copy path is de-initialized.
Zero-copy is assumed to be always preferable over the primary GPU and CPU copy
paths. Whether this is universally true remains to be seen.
This patch has one unhandled failure mode: if zero-copy path first succeeds and
then fails later, there is no fallback and the output is left frozen or black.

With all the three paths this is quite a handful of code, and it was mostly
duplicated in two places. A follow-up patch would need to introduce a third
copy of it. Therefore move the code into a helper function.
There are two behavioral changes:
- The format error now prints the string code as well, because it is easy to
read.
- The g_debug() in init_dumb_fb() is removed. Did not seem useful.

There will be another place where I need to release the dumb buffers but not
destroy the whole secondary_gpu_state, so extract this bit of code into a
helper.
The checks of fb_id are dropped as redundant with the check already in in
release_dumb_fb ().
https://gitlab.gnome.org/GNOME/mutter/merge_requests/810
release_dumb_fb () checks 'map' to see if anything needs freeing. Other places
are checking fb_id instead. The checks maybe redundant, but let's reset all
fields here while at it, so that all the checks work as expected.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/810
Simplify the bo freeing functions by not checking what the copy mode is. This
matches what swap_secondary_drm_fb () already does. g_clear_object () is safe
to call even if the value is already NULL.
The copy mode does not change mid-operation. If it did, this change would
ensure we still clean up everything. So this is more future-proof too.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/810
To mirror what happens in meta_onscreen_native_swap_buffers_with_damage(), warn
here too if next_fb is not NULL. This makes it clear to the reader of what the
expectations are inside this function.
Ensuring next_fb is NULL as the first thing in the function will make all error
paths equal: no longer some failures reset next_fb while others don't. Removing
such special cases should reduce surprises.

If we end up trying to do a mode set on a DRM state that has already
changed behind our back without us yet having seen the hotplug event we
may fail with `EINVAL`. Since the renderer layer doesn't handle mode set
failure, it'll still try to page flip later on, which will then also
fail. When failing, it'll try to look up the cached mode set in order to
retry the mode set later on, as is needed to handle other error
conditions. However, if the mode set prior to the page flip failed, we
won't cache the mode set, and the page flip error handling code will get
confused.
Instead of asserting that a page flip always has a valid cached mode set
ready to look up, handle it being missing more gracefully by failing to
mode set. It is expected that things will correct themself as there
should be a hotplug event waiting around the the corner, to reconfigure
the monitor configuration setting new modes.

The method `relative_motion_across_outputs` is used to adjust the
distance/delta of a mouse movement across multiple monitors to take the
different scale factors of those monitors into account. This works by
getting the adjacent monitors that the movement-line/vector intersects
with and adjusting the final position (or end point of the
movement-line) by multiplying the parts of the line spanning across
different monitors with the scale factors of those monitors.
In the end of this calculation, we always want to set the new end
coordinates of the relative motion to the new end coordinates of the
adjusted movement-line. We currently only do that if all adjacent
monitors the line is crossing actually exist, because only then we end
up inside the "We reached the dest logical monitor" else-block and set
`x` and `y` to the correct values. Fix that and make sure the returned
values are also correct in case an adjacent monitor doesn't exist by
adding separate `target_x` and `target_y` variables which we update during
each pass of the while loop so we're always prepared for the while loop
exiting before the destination monitor was found.
Thanks to Axel Kittenberger for reporting the initial bug and tracking
the issue down to `relative_motion_across_outputs`.

Touch-wise, those are essentially giant touchpads, but have no buttons
associated to the "touchpad" device (There may be pad buttons, but
those are not mouse buttons).
Without tap-to-click/drag, touch in those devices is somewhat useless
out of the box. Have them always enable these features, despite the
setting.

Using the same scale for the window as the
logical monitor only works correctly when having
the experimental 'scale-monitor-framebuffer'
feature enabled.
Without this experimental feature, the stream
will contain a black screen, where the actual
window only takes a small part of it.
Therefore, use a scale of 1 for the non-
experimental case.
Patch is based on commit 3fa6a92cc5.

Presumably this function is supposed to be like
meta_kms_impl_simple_handle_page_flip_callback() but the condition in the
if-statement is inverted. Fix the inversion to make these two functions look
alike.
This is part 2 of 2 fixing a complete desktop freeze when drmModePageFlip()
fails with EINVAL and the fallback to drmModeSetCrtc() succeeds but the success
is not registered correctly as completed "flip". The freeze occurs under
wait_for_pending_flips() which calls down into meta_kms_impl_device_dispatch()
which ends up poll()'ing the DRM fd even though drmModeSetCrtc() will not
produce a DRM event, hence the poll() never returns. The freeze was observed
when hotplugging a DisplayLink dock for the first time on Ubuntu 19.10.
This patch makes meta_set_fallback_feedback_idle() actually end up calling into
notify_view_crtc_presented() which decrements
secondary_gpu_state->pending_flips so that wait_for_pending_flips() can finish.
