Even though cogl_framebuffer_flush() was supposed to be enough,
it ends up creating streams with odd visual glitches that look
very much like unfinished frames.
Switch back to cogl_framebuffer_finish(), which is admittedly
an overkill, but it's what works for now. There is anedoctal
evidence showing it doesn't incur in worse performance.

Much like monitor streaming, implement window streaming by
making the window actor draw itself with a paint context
that used the passed framebuffer.
Now that all MetaScreenCastStreamSrc subclasses implement
blit_to_framebuffer, remove the conditional check from
meta_screen_cast_stream_src_blit_to_framebuffer().

Implement PipeWire's add_buffer and remove buffer, try and export
a DMA buffer first and, on failure, fallback to memfd.
When DMA buffers are successfully created and shared, blit the
framebuffer contents when drawing instead of downloading the pixels.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1086
Create a new gbm_bo using the same given geometry, and export the new
bo's DMA buffer fd. The new bo lives as long as necessary to be used,
and reused, by PipeWire.
Unfortunately, PipeWire doesn't support modifiers properly, so use the
linear format for now. For now, a hardcoded format of DRM_FORMAT_XRGB8888
is set, so we don't need to negotiate the format with PipeWire early.

If the cursor sprite does not match the scale factor or transformation
of the monintor, we currently fall back to a software cursor, causing
redraws of the shell. This commit implements scaling and transforming
of the cursor sprite, so we can use it with hardware planes, too.
This commit does the following steps:
1. Make sure we reupload the cursor image if the cursor is over
a logical monitor not matching the scale or transform from the previous
update.
2. Before upload to the hardware plane, scale and transform the cursor
image if possible and necessary.
3. Make sure we always use the hardware cursor if possible (only fall
back to software/OGL cursor if it is visible on multiple logical monitors
with differet scales/transforms).
4. Transform or scale the cursor coordinates if necessary.

In Wayland clients can commit transformed surfaces, so the compositor
can directly use them on hardware planes. We already support that
for other surfaces, this is the first step to also support it on
cursor sprites.

This may be used indirectly before creation as we dispatch libinput events
right after creation (to let input devices be known), so those device
additions would trigger the touch-mode checks.
Creating it in advance results in checks being correctly performed, although
redundantly.

When applying a configuration to XRANDR, we first disable CRTCs that
happen to extend outside of the to-be X11 screen size. While doing so,
we fail to actually check whether the CRTC is active or not, meaning
we'll try to query the content of the CRTC configuration even though it
has none, leading to a NULL pointer dereference.
Fix this by simply ignoring non-configured CRTCs.

Prior to this commit the stage was drawn separately for each logical
monitor. This allowed to draw different parts of the stage with
different transformations, e.g. with a different viewport to implement
HiDPI support.
Go even further and have one view per CRTC. This causes the stage to
e.g. draw two mirrored monitors twice, instead of using the same
framebuffer on both. This enables us to do two things: one is to support
tiled monitors and monitor mirroring using the EGLStreams backend; the
other is that it'll enable us to tie rendering directly to the CRTC it
will render for. It is also a requirement for rendering being affected
by CRTC state, such as gamma.
It'll be possible to still inhibit re-drawing of the same content
twice, but it should be implemented differently, so that it will still
be possible to implement features requiring the CRTC split.

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.

On x11 we emulate pointer events from touch events as long as there's
only one touchpoint on screen, this obviously leads to x11 sending us
crossing events triggered by the emulated pointer. Now if we get a leave
event and set the stage of the ClutterInputDevice to NULL, new touch
events will be discarded by clutters backend because the core pointer
doesn't have a stage associated. This means Mutter completely loses
state of a touchpoint as soon as it crosses a shell actor.
An easy reproducer for this issue is to start the four-finger-workspace
gesture above a window and to move the pointer emulating touch outside
of the window, this will freeze the gesture as the gesture no longer
receives touch events.
To fix this, stop tracking stage changes on crossing events and simply
leave the ClutterInputDevice stage as-is. In our case there is only one
stage anyway and that won't change in the future.

On a Surface Pro 2017, touch-mode is currently only detected correctly
after detaching and attaching the Type Cover (detachable keyboard) once,
it seems that `has_external_keyboard` is only set to the correct value
after MetaSeatNative is initialized.
So fix that and call `update_touch_mode()` once again when the object is
initialized and the `has_external_keyboard` and `has_touchscreen`
properties have been finally updated.

Allow screen casters (e.g. VNC remote desktop services) to ask for
animations to be inhibited, in order to lower the number of frames sent
over the network.
Currently only sets a field on the screen cast session object. Later
it'll be exposed via the remote access handle and via D-Bus by
gnome-shell.

We didn't log what we enabled, just g_info():ed what failed to be
enabled. Change this to g_warning() what failed to be enabled, and
g_message() on what was enabled, so that both will be visible in the
logs.

We preserve the core one, which represents the union of all input
devices. It might make sense to make this per-seat in the future,
but certainly the per-device granularity is unused (at last!) and
useless.

Devices have capabilities that other parts need to know about. Instead
of having them probe using drmMode* API, outsource this to
MetaKmsDevice. Currently the only capability tracked is HW cursor size.

Turns the cursor setting and movement into cursor plane assignment
primitives. In the current simple implementation, this in turn
translates into legacy drmModeSetCursor() and drmModeMoveCursor() calls.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/930
A cursor plane can now be assigned, and for the simple KMS
implementation, it'll translate into drmModeSetCursor() and
drmModeMoveCursor() calls.
When assignments failed, the cursor planes that failed to be assigned
are communicated via the feedback object.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/930
The current API as all synchronous, so they can be made to return
feedback immediately. This will be needed for the cursor renderer which
needs to know whether it should fall back to OpenGL cursor rendering.

meta_kms_update_process_..() makes it sound like it's a MetaKmsUpdate
function called update_..() but in fact it's a MetaKms function that
calls the corresponding process-update impl function. Clear up this
naming confusion.
