Not used by any external modules, so no need to keep it in public API.
Since it's used by DRI, still needs the _X_EXPORT flag, as long as DRI
is a dynamically loaded module.

On DRM lease connector withdrawn event, Xwayland would free the
corresponding xwl_output offered for lease.
However, the pointer is still referenced from the rrLease->outputs[],
meaning that trying to clean up the RANDR DRM leases as done with commit
ef181265 (xwayland: Clean up drm lease when terminating) would cause a
use after free and random crashes.
To avoid that issue, on the connector withdraw event, set the connector
withdrawn flag but do not to remove (i.e. free) the xwayland output if
its is offered for lease.
Then, once the lease is terminated, check for the xwl_outputs with a
withdrawn connector and remove them (once we have no use for them
anymore.
Note that we cannot do that cleanup from xwl_randr_terminate_lease() as
removing the xwl_output will free the RRcrtc resources, which checks for
leases in XRANDR, and calls RRTerminateLease(), which chains back to
xwl_randr_terminate_lease().
v2: Use a "withdrawn_connector" flag to mark outputs to remove (Xaver)

In xwl_randr_request_lease(), the code checks first for leased device,
and then checks for existing output for lease.
The former assumes there are outputs for lease whereas the latter checks
for the output, connector and lease.
So if there is any existing rrLease->outputs[]->devPrivate unset, the
code would crash on a NULL pointer dereference on the first sanity check
before having a chance to reach the second check that would have caught
the problem.
Invert the sanity checks so that we would catch this first and return a
BadValue instead of possibly segfaulting.

Use the connector name as basis for the Xwayland output name in XRANDR,
similar to what we do for regular outputs, instead of the generic
"XWAYLAND<n>" name which changes every time the output is leased.
Prefix the actual name with "lease-" to distinguish from duplicate names
from the regular outputs.
v2: avoid duplicate names (Simon)
v3: Move the check for duplicates to xwl_output_set_name() (Simon)

Xwayland uses an output serial number it increments each time a new
Wayland output is added.
On server regeneration, that static value is not cleared, and therfore
the output numbers keep increasing each time the Xserver restarts.
To avoid that issue, make the output serial part of the xwl_screen,
which gets recreated on server regeneration, so that index is reset to 0
automatically on server regeneration.

drm_lease_device_handle_released uses the wrong pointer type in the

This commit allows X11 clients running through Xwayland to lease
non-desktop connectors from the Wayland compositor by implementing
support for drm-lease-v1.
In order to not deadlock with the Wayland compositor if its response
to a lease request is delayed, the new interface in _rrScrPriv
introduced in the last commit is used, which makes it possible to
block the X11 client while a response is pending.
Leasing normal outputs is not yet supported, all connectors offered
for lease will be advertised as non-desktop.
