The other end of the PipeWire stream can set the buffer data type to a
bitmask of supported buffer types. We should respect this, and not
attempt to allocate a DMA buffer if it isn't asked for.

Instead of getters, pass the width, height and stride around when
relevant. This also removes the redudant "stream_size" and
"stream_height" variables from the src struct, as they are already part
of the video format.

Mutter freezes Xwayland commits when resizing windows, and thaw them in
the window actors' after_paint() for X11.
Yet, after_paint() could be never called, as when a new window is mapped
while the overview is active in gnome-shell.
As a result, the content of the X11 window will remain invisible to the
overview.
Add a new window actor API to tell whether commits can be frozen. For
Wayland window actors, this always return FALSE, whereas for X11 window
actors, it checks whether the Clutter actor is mapped.

When (un)maximizing, (un)fullscreening, the move/resize action is
flagged with 'ACTION_MOVE' and 'ACTION_RESIZE' , while e.g.
'appears-focus' does not.
When a client misbehaved and didn't immediately reply to a configure
request with a commit with the corresponding ack_configure, the
following commit would trigger a oddly timed move, making the window
appear to move back to a previous position.
Avoid this issue by only carrying over the target window position if the
configuration actually contained a new position.
We cannot only rely on the flags however, as e.g. a new position should
be respected during interactive resize, even though only 'ACTION_RESIZE'
is passed in such scenarios.
Do the same for the size, except if the window state dictates that the
size is fixed to a certain size, e.g. being fullscreen or maximized.

Mutter needs to fetch the X11 Window ID from the onscreen and did that
by using an X11 specific API on the CoglOnscreen, where the X11 type was
"expanded" (Window -> uint32_t). Change this by introducing an interface
called CoglX11Onscreen, implemented by both the Xlib and GLX onscreen
implementations, that keeps the right type (Window), while avoiding X11
specific API for CoglOnscreen.

Instead of calling "init_onscreen()" on two different separate vtables
from the allocate() funtion, just have the CoglOnscreen sub types
themself implement allocate() and initialize in there.

Thins means that e.g. MetaOnscreenNative now inherits CoglOnscreenEgl,
which inherits CoglOnscreen which inherits CoglFramebuffer, all being
the same GObject instance.
This makes it necessary to the one creating the onscreen to know what it
wants to create. For the X11 backend, the type of renderer (Xlib EGL or
GLX) determines the type, and for the native backend, it's currently
always MetaOnscreenNative.
The "winsys" vfunc entries related to onscreens hasn't been moved yet,
that will come later.

To get meta-renderer-native.c down to a bit more managable size, and to
isolate "onscreen" functionality from other (at least partly), move out
the things related to CoglOnscreen to meta-onscreen-native.[ch].
A couple of structs are moved to a new shared header file, as
abstracting those types (e.g. (primary, secondary) render devices) will
be dealt with later.

The mutter naming convention for types and their instance variables is:
Type name:
[Namespace][BaseName][SubType]
Instance name:
[base_name]_[sub_type]
This means that e.g. CoglOnscreenGLX is renamed CoglOnscreenGlx, and
glx_onscreen is renamed onscreen_glx. This is in preparation for
GObjectification.

Makes sure that monitor specs which may be read from EDID data do not
contain characters that are invalid in XML. Makes it possible to restore
monitor configs of monitor models with characters such as '&' in them.
To make this change not break any tests, the sample monitor configs need
to be adjusted as well. Apostrophes don't strictly have to be escaped in
XML text elements. However, we now do escape the elements in
`<monitorspec>` specifically.

Previously the wl_resource and MetaWaylandGtkSurface corresponding to
any client gtk_surface have been kept around until the exit of the
client due to the client side destroy method not signaling the
destruction to the server. Ideally the protocol would have specified a
destroy request marked as destructor to handle this automatically,
however this is no longer possible due to the destroy method being
implicitly generated in the absence of an explicit request in the
protocol. Adding a destroy request marked as destructor now would
generate a new destroy method that unconditionally would send the
request to the server, which would break clients running on servers not
supporting that request.
So instead of modifying the destroy request add a new "release"
destructor, that indicates to the server that it can release the
resource. This can be optionally be used by clients depending on the
server protocol version.

The MetaWaylandSurface corresponding to a MetaWaylandGtkSurface can be
destroyed before the MetaWaylandGtkSurface is destroyed. In its destroy
function MetaWaylandSurface however was unsetting the destructor of the
correspnding resource along with the gtk_surface1 interface
implementation. This was done to prevent further gtk_surface1 requests
on a NULLed MetaWaylandSurface, if it has been destroyed before the
MetaWaylandGtkSurface.
It would be enough to just unset the resource implementation, while
keeping the destructor to fix this leak. However the following commit
will rely on the implementation being available after the
MetaWaylandSurface has been destroyed. So instead introduce NULL checks
for all functions that can be called on the gtk_surface1 interface and
do not unset the implementation.

If the monitor configuration changed, even though the streamed monitor
didn't change, we'd still fail to continue streaming, as we failed to
update the stage watchers, meaning we wouldn't be notified about when
the stage views were painted.
Fix this by reattaching the stage watches, i.e. update the painted
signalling listeners to listen to the right views, when monitor changes
happens.

Make the API used more shared and better named.
meta_monitor_manager_on_hotplug() was renamed
meta_monitor_manager_reconfigure(), and meta_monitor_manager_reload()
was introduced to combine reading the current state and reconfiguring.

Fullscreen X11 windows that attempt to change the resolution on Wayland
use a surface viewport to achieve this without affecting the resolution
of the display. This however also means that pointer events will be
delivered in the display coordinates while the code handling the window
frame is not aware of any such viewport scaling. So a right click
outside of the area corresponding to the new resolution will not be
considered to be on the client area. And since the only area that is
ignored when determining whether to perform the right click action, such
as opening the context menu, is the client area, this will result in the
action being performed, despite happening on the (scaled) client area.
While it would be possible to scale the event coordinates so that
get_control() correctly determines the frame element the cursor is on,
viewport scaling only affects fullscreen windows. Since fullscreen
windows have no frame, we can always assume that if the window gets
delivered an event for a fullscreen window, it is on the client area
without doing any additional calculations.

We remove pending pings when unmanaging a window, but currently
don't prevent new pings to be scheduled after that.
The previous commit fixed a code path where this did indeed happen,
but as the result of gnome-shell trying to attach a Clutter actor
to a non-existent window actor is pretty bad, also guard can_ping()
against being called for an unmanaging window.

This seems to have been the default in the past, but was (accidentally?) modified
by 8adab0275.
For GNOME 40, we'll be returning to our root with horizontal workspaces, so instead
of overriding it in GNOME Shell side, change the default back to what it once was.
