5c500ad402 backend: Move GPU ownership from the monitor manager to the backend
Lets work towards making MetaMonitorManager about managing monitors, and
not about managing GPUs. This changes other units to keep a pointer to
the backend instead of a monitor manager, in case their ownership
changed, or their main usage of the monitor manager was to look up GPUs.

stage: Introduce MetaStageWatch and family
MetaStageWatch, watch modes and the watch function are part
of the new stage view watching API. It's design does not
rely on signals on purpose; the number of signals that would
be emitted would be too high, and would impact performance.

MetaStageWatch is an opaque structure outside of MetaStage.

This will be used by the screencast code to monitor a single
view, which has a one-to-one relatioship to logical monitors.

9213574870 renderer/native: add missing eglTerminate in EGLDevice error path
Currently the EGLDevice code gets the display and calls eglInitialize.
As a follow-up it checks the required EGL extensions - technically it
could check the EGL device extensions earlier.

In either case, eglTerminate is missing. Thus the connection to the
display was still bound.

This was highlighted with Mesa commit d6edccee8da ("egl: add
EGL_platform_device support") + amdgpu.

In that case, since the eglTerminate is missing, we end up reusing the
underlying amdgpu_device due to some caching in libdrm_amdgpu. The
latter in itself being a good solution since it allows buffer sharing
across primary and render node of the same device.

Note: we should really get this in branches all the way back to 3.30.

b01edc22f3 backends/x11: Do not reload keymap on new keyboard notifications
XkbNewKeyboardNotify informs the client that there is a new keyboard
driving the VCK. It is essentially meant to notify that the keyboard
possibly has a different range of HW keycodes and/or a different
geometry.

But the translation of those keycodes remain the same, and we don't
do range checks or geometry checks (beyond using KEY_GRAVE as "key
under Esc", but that is hardly one). It seems we can avoid the
busywork that is releasing all our passive grabs, reloading the keymap
and regenerating the keycombos and restoring the passive grabs.

fecc57ddf0 renderer-native: Reference count front buffers
Start reference counting front buffers instead of assuming we know
their (scanout) lifetimes.

Functionally, this should not change anything.

dae2c1d420 backends/native: Add rt-scheduler experimental key to set RT scheduling
This is similar to a change in kwin:
https://blog.martin-graesslin.com/blog/2017/09/kwinwayland-goes-real-time/

If the experimental features key has "rt-scheduler", make it claim the lowest
of RT scheduler priorities, this will be both educated to other RT processes
and improves responsiveness wrt all other processes.

This can only work if mutter/gnome-shell process receives CAP_SYS_NICE
somehow, e.g.: "setcap CAP_SYS_NICE=+ep `which gnome-shell`"

ae6d9e35bd backends: Fallback to builtin panel for devices where all heuristics fail
This is 1) relatively likely as not all touchscreens are nice enough to
report a device size that will help us here and 2) Better than nothing if
everything fails anyway, as it will break on multi-monitor and non-default
monitor rotations.

1ca0fdc928 idle-monitor: Postpone dispatching of idle timeout if not ready
If we update the ready time while the source is already in the
to-dispatch list, changing the ready time doesn't have any effect, and
the source will still be dispatched. This could cause incorrect idle
watch firing causing the power management plugin in
gnome-settings-daemon to sometimes turn off monitors due to it believing
the user had been idle for some time, while in fact, they just logged
back in.

Fix this by not actually dispatching the idle timeout if the ready time
is in the future when actually dispatching.

23a8ea2821 idle-monitor: Use G_SOURCE_CONTINUE instead of TRUE

28419cdedf renderer/native: Check primary GPU supports EGL
Since "renderer/native: make EGL initialization failure not fatal" it is
possible, under specific failure conditions, to end up with a primary GPU whose
EGL initialization failed. That cannot work.

3b46a8cd70 renderer/native: Make EGL initialization failure not fatal
The failure to initialize EGL does not necessarily mean the KMS device cannot
be used. The device could still be used as a "secondary GPU" with the CPU copy
mode.

If meta_renderer_native_create_renderer_gpu_data () fails,
meta_renderer_native_get_gpu_data () will return NULL, which may cause crashes.
This patch removes most of the failures, but does not fix the NULL dereferences
that will still happen if creating gpu data fails.

This patch reorders create_renderer_gpu_data_gbm () so that it fails hard only
if GBM device cannot be created, and otherwise always returns an initialized
gpu data structure. Users of the gpu data structure are responsible for
checking egl_display validity.

The GBM device creation failure is a hard failure because presumably GBM is
necessary for cursors.

b2d0184c6e renderer-native: Freeze frames while retrying to page flip
We're currently always waiting for unfinished page flips before flipping
again. This is awkward when we are in an asynchronous retry-page-flip
loop, as we can synchronously wait for any KMS page flip event.

To avoid ending up with such situations, just freeze the frame clock
while we're retrying, then thaw it when we succeded.

3cc3b7526c renderer-native: Fake page flipping slower when power saving
We rely on the frame clock to compress input events, thus if the frame
clock stops, input events are not dispatched. At the same time, there
is no reason to redraw at a full frame rate, as nothing will be
presented anyway, so slow down to 10Hz (compared to the most common
60Hz). Note that we'll only actually reach 10Hz if there is an active
animation being displayed, which won't happen e.g. if there is a screen
shield in the way.

53b59d8bff renderer-native: Fake page flipped if power saving when retrying
When we're in a page-flip retry loop due to the FIFO being full
(drmModePageFlip() failing with EBUSY), we should not continue to try
when starting to power save, as that means we're blocking new frames,
which itself blocks input events due to them being compressed using the
frame clock.

We'd also hit an assert assuming we only try to page flip when not power
saving.

Thus, fake we flipped if we ended up reaching a power saving state while
retrying.

40e7e5d356 renderer-native: Fix page flip retry timeout calculation
It tried to add a (implicitly casted) float to a uint64_t, and due to
floating point precision issues resulted in timestamps intended to be
in the future to actually be in the past. Fix this by first casting the
delay to an uint64_t, then add it to the time stamp.
