By default, Xwayland (as any Wayland client) uses the keymap set by the
Wayland compositor using the standard Wayland protocol.
There are some specific uses cases where a user would want to let the
X11 clients control the keymap. However, the Wayland compositor may
(re)send the keymap at any time, overriding whatever change was made
using the X11 mechanisms.
Add a new "-nokeymap" option to Xwayland to instruct Xwayland to simply
ignore the standard Wayland mechanism to set the keymap, hence leaving
the control entirely to the X11 clients.

With EI support wired to XTEST, and oeffis being enabled unconditionally
means that Xwayland will always go through the XDG portal for XTEST when
supported.
While this the intended behavior for the general use case of Xwayland
running rootless on a desktop compositor, that breaks when Xwayland is
running on a nested compositor, because the portal is for the entire
session and not limited to the nested Wayland compositor.
Xwayland itself, as a regular Wayland client, has no way to tell that it
is running on a nested compositor.
So to keep backward compatibility with existing (and also common) use
cases such as nested compositors, best is to disable support for the XDG
portal by default, and add a new command line option "-enable-ei-portal"
for the Wayland compositors (who spawn Xwayland rootless) to explicitly
enable support for the input emulation XDG portal in Xwayland.
A Wayland compositor running nested should not use that command line
option with Xwayland.

This extension exists to serve one purpose: reliably identifying
Xwayland. Previous attempts at doing so included querying root window
properties, output names or input device names. All these attempts are
somewhat unreliable. Instead, let's use an extension - where that
extension is present we have an Xwayland server.
Clients should never need to do anything but check whether the extension
exists through XQueryExtension or search through XListExtensions.
This extension provides a single QueryVersion request only, and
that is only to provide future compatibility if we ever need anything
other than "this extension exists" functionality.

When running rootless as well as rootful, Xwayland gets its outputs
configuration from the Wayland compositor.
When running rootful, it means that we end up with a large black

and there is no way for set the desired size of the Xwayland window.

Xwayland.
That option has no effect when Xwayland is running rootless.

Adds a -force-xrandr-emulation cmdline switch that always exposes extra
modes when viewporter isn't exposed by the Wayland compositor.
Having the additional modes exposed by the X server is important for
games to function and be configured
Compositors, such as Gamescope (the compositor for Steam Deck),
support only a single window that is rendered in the centre of the
screen that is scaled up to fill the screen by the compositor based
on some user scaling settings.
Exposing viewporter, wouldn't make sense here, and could mislead native

Xwayland may open a fair amount of file descriptors for passing Wayland
buffers, even more so when using the `wl_shm` either for the pointer
cursors or for when GLAMOR is not usable.
As a result, Xwayland may hit the (soft) limit of file descriptors
leading to a Wayland protocol error and the termination of Xwayland.
To mitigate that risk, raise the limit to the maximum (hard) limit of
file descriptors (unless of course the limit was set explicitly from the
command line with "-lf").
Note that for completeness, the Wayland compositor may have to do the
same, otherwise the limit might get reached on the compositor side as
well.
