In Wayland, mouse coordinates are not updated after all x11 clients have left,
causing the mouse information to remain at the position left by the last x11
client. However, if CheckMotion is called at this point for other reasons
(such as window mapped, reactive, etc.), xwayland might continue to send enter
events to x11 clients, even if the mouse is actually on a Wayland client.
This MR introduces and checks pointer_enter_count to determine if the mouse
has left an x11 client and is now on a Wayland client. When it's confirmed
that the mouse is no longer on an x11 client but on a Wayland client,
returning TRUE in sprite_check_lost_focus causes XYToWindow to return to the
root window, preventing further enter events from being sent to x11 clients.

When running rootful, i.e. as a regular Wayland client, Xwayland needs
to wait for the initial configure event before posting its initial
buffer and commit the surface.
Not doing so may cause mutter to log a warning when Xwayland is started
rootful:
| Buggy client (org.freedesktop.Xwayland) committed initial non-empty
| content without acknowledging configuration, working around.
Or running rootful with libdecor:
| Client provided invalid window geometry for xdg_surface#nn
| (org.freedesktop.Xwayland - Wnn (Xwayland on :nn)). Working around.
|
| Buggy client (org.freedesktop.Xwayland) committed initial non-empty
| content without acknowledging configuration, working around.
This is actually mutter being nice, as this should be treated as a
protocol error and Xwayland would be terminated.
To avoid the issue, we need to hold on attaching a buffer and committing
the surface until we actually get the first configure event from the
compositor.
That, however, only applies to rootful mode, so we can leave the default
code path for rootless untouched.

Up to the native mode, as reported by the wl_output protocol.
This ensures that fullscreen apps can always use the native mode.
Also ensure the root window is large enough for the output at its
current position with the native mode.

In the rootless case, Xwayland receives pointer motion events only while
the pointer is over one of its Wayland surfaces, so there's no need for
constraining them to RandR boundaries.
This also avoids them getting spuriously constrained when using RandR
emulation for modes larger than the default one.

Xwayland was sending incorrect pointer coordinates to X clients on
pointer enter events.
This was caused by calling CheckMotion() with a NULL event, which
prevented the pointer sprite hot coordinates from being updated
properly.
Fix this by constructing a proper DeviceEvent of type ET_Enter in
pointer_handle_enter, initializing it with the current timestamp
and EVENT_SOURCE_FOCUS, and passing it to CheckMotion() instead
of NULL.
This ensures the pointer sprite coordinates are correctly updated
when the pointer enters a window.

InputOnly windows aren't relevant here.
E.g. mutter-x11-frames uses GTK4, which creates a 1x1 InputOnly child
window, which previously prevented this code from working as intended.
v2: (Olivier Fourdan)
* Rename output_child -> input_output_child.
* Add comment in get_single_input_output_child explaining why we return
NULL if input_output_child is already non-NULL.

If the WM client reparents a window, mark the new parent as a WM window.
This helps with current mutter, where decoration windows are created by
a separate mutter-x11-frames client instead of the WM client. There
might be other compositors doing something similar now or in the future.
v2:
* Skip the whole unwrap-and-call-down dance in xwl_reparent_window if
xwl_screen->ReparentWindow is NULL.

For cpu_family(), meson returns "sparc" for 32-bit sparc,
and "sparc64" for 64-bit sparc, regardless of the OS in use.
For cpu(), meson returns values like "sun4v" on Solaris/SPARC,
and doesn't promise stability of the values, or portability across
OS'es, unlike cpu_family().

Commit d36f66f15d ("Check for duplicate output names") would walk the
list of existing outputs and leases to check that no other existing
output has the same name.
The change however, inadvertently reused the regular screen outputs when
searching the leased names.
Fix this by using the lease name, not the regular output names that we
already checked just above.
Found by SAST tool Svace.

Commit 54f8fc4090 introduced the use of
wl_surface::set_buffer_scale, which is only available starting with
version 3 of the wl_compositor protocol. Because we already prefer
version 4 when available, this went unnoticed but broke versions 1, 2
and 3 when reaching the wl_surface::set_buffer_scale call.
This restores functionality for version 3 and properly document that
versions 1 and 2 are not supported anymore.

The commit referenced below partially resolved an issue with grabs being made
on the root window. Unfortunately it assumes that the application uses
the same client for all windows. VMware Workstation uses nested windows
for each VM, each of which runs its own process with this own client.
Theses windows are managed by the GUI which is the top level for the
application and maps the windows based on which tab is selected.
Because the VM windows issue a grab on the root window and don't share
the same client as the GUI, grabs don't work properly with global shortcut
inhibition being completely broken.
Getting the parent top-level of the nested windows fixes this issue.

Previously, when parsing multiple configuration files containing the same
section names, only the last occurrence of each section would be retained.
Earlier definitions were silently discarded due to unconditional memory
allocation and overwriting of pointers during parsing.
This resulted in incomplete or incorrect configuration state when users
intended to merge or extend configuration through multiple files.
The section parsing functions in Files.c, Flags.c, and Module.c now
accept existing section pointers. These functions allocate new memory only
if the input pointer is NULL, preserving earlier data when re-parsing.
read.c has been updated to detect and pass existing section pointers when
encountering duplicate sections across files, preventing loss of prior content.
With these changes, the parser properly accumulates and merges configuration
data across multiple files, ensuring that all relevant settings are preserved.

Xwayland dispatches tablet tool tip events immediately when they arrive.
With compositors such as mutter and sway, it is not an issue because
their libinput backends synthetize axis events before tip events. In
other words, axis data and the tip status belong to different frames.
On the other hand, kwin sends axis and tip events in a single frame
(its libinput backend generates a single tip event with axis data
attached to it). Since the tip events are dispatched immediately,
they can have wrong information associated with them, for example tool
position or pressure. It results in undesired "streaks" when the user
presses the tablet tool against the tablet.
