Subject: [PATCH] wayland: do not leak shortcut inhibit data
We would free the shortcut inhibit data only when the client destroys
its request, which is not the case when the clients itself is
destroyed, leading to a leak of the shortcut inhibit data.
Free the data on resource destruction instead, and simply destroy the
resource on destroy request.

Subject: [PATCH] wayland: Keep the inhibit shortcut dialog
On Wayland, the grab()/ungrab() in gtk+/gdk are wired to the shortcut
inhibitor mechanism, which in turn shows the dialog, which can take
focus away from the client window when the dialog is shown.
If the client issues an ungrab() when the keyboard focus is lost, we
would hide the dialog, causing the keyboard focus to be returned to the
client surface, which in turn would issue a new grab(), so forth and so
on, causing a continuous show/hide of the shortcut inhibitor dialog.
To avoid this issue, keep the dialog around even if the shortcut inhibit
is canceled by the client, so that the user is forced to make a choice
that we can reuse on the next request without showing the dialog again.
Instead of hiding the dialog when the shortcut inhibitor is destroyed by
the client, we simply mark the request as canceled and do not apply the
user's choice.
