Always ensure that the MetaSurfaceContainerActorWayland is aligned to physical
pixel boundary in preparation for fractional-scale-v1 protocol support.
This introduces an override of ClutterActor::apply_transform vfunc for
MetaSurfaceContainerActorWayland that always ensures the actor content is aligned
to physical pixel boundary.

The template already does this at the end, so this step is
pointless in the best case.
When building the x86-64 image, we install additional packages
afterwards, so the repo metadata is downloaded again.

The only consumer of this type of rect was the scissor clipping,
which was removed by the previous commit.
Remove window rects from CoglClipStack, and all dependent code.

A failing allocation is non-fatal here, however if it fails later in a
lazy allocation triggered by `cogl_framebuffer_create_timestamp_query()`
we end up crashing. Thus force the allocation early, like we already do
in other places.

While it's obviously good to trap possible errors from X calls, we are
mixing the Clutter error trap with the MetaX11Display one for these
calls.
This may result in situations where a X call within a Clutter error
trap fails, but it's actually handled in these sections using the
MetaX11Display error trap. This one will consider the serial out
of the "handled" parts and raise an error.
It is better to stay consistent here, and use the same error traps
than the rest of the X11 backend.

When the X11 display is actually XWayland there's no point to delay the
compositor selection, given that mutter itself is the compositor and
doing this may cause the first X11 client that starts not to receive the
right information (and in some cases misbehave).
Since some toolkits are not handling the compositor selection changes
properly at later times, let's make their life easier by just
initializing the selection as early as the other X11 properties, given
that in this case there's nothing to replace.

Since c390f70edc ("backend: Set up and use ownership chains")
the type of the ClutterInputDevice object's "meta-input-settings-xdevice"
data is `DeviceHandle`, but that commit failed to change the one place
where the object data is queried. As a consequence, that part still
considers it to be an `XDevice`, so everything that uses the return
value of `device_ensure_xdevice()` works with invalid data. Furthermore,
`device_handle_free()` incorrectly uses the `user_data` as the argument
for `XCloseDevice()` leading to a double free.

Otherwise drivers would be free to alter the buffer content. While no
driver is known to do so, it's probably good to make things explicit.

The DMA buffer paths vs MemFd paths differ slightly in when content is
recorded. This was in some places done by trying to record but bail if
the dequeued buffer had the wrong type. This is problematic for two
reasons: we'd update the timestamp even if we refused to record, making
the follow-up attempt fail, and we'd dequeue and queue buffers that
didn't get any content, meaning the receiving end would see empty
buffers potentially with only cursor updates.
Fix this by keeping track if a stream is DMA buffer able or not, and
don't attempt to record at all in the places we would previously require
DMA buffers. This avoids both issues: we don't dequeue/queue pw_buffers
that we refuse to record to, and we won't update the recorded timestamp
when we didn't intend to record to begin with.

This aims to reduce the amount of pixels that have to be redrawed on the
screen on a clipped actor redraw in case using the union of two
different clips in a surface will substantially increase the redrawn
area.
This should not result in excessive memory consumption as callers of
`clutter_actor_queue_redraw_with_clip` are expected to ensure that the
redraw clip rectangles are adequately deduplicated.

mutter-clutter is a private library that is only used by the shell and
not meant to be ABI/API compatible in between versions, so there's no

Hides libdisplay-info under a build time default-off flag,
provides provision to parse essential edid parameters with
APIs provided by libdisplay-info. This implementaion increases
readibility, avoids code duplication and decreases complexity
of edid parsing.
