weston maintains a copy of the most recently selected "thing" - it picks
the first available type when it copies, and saves that one only.
When an application quits weston will make the saved selection active.
When xwm sees the selection set it will check if any of the offered types
are text. If no text type is offered it will clear the selection.
weston then interprets this in the same way as an application exiting and
causing the selection to be unset, and we get caught in a live lock with
both weston and xwayland consuming as much cpu as they can.
The simple fix is to just remove the test for text presence.

The surface can have an undefined resource in certain situations (such
as with xwayland). So, since NULL is a valid state for this parameter,
and since the wl_resource_*, etc. calls require their parameters to be
non-NULL, make a practice of always checking the surface resource before
making wayland calls.

In order to keep things simple, weston-dnd made a few choices that
turn out to be unrealistic, a few tweaks have been done to make it
less of a playground demo:
- It now caters for copy/move operations, instead of just move,
which still remains the default nonetheless.
- As "move" operations are no longer assumed, the item isn't removed
on start_drag, instead it is made translucent until the drag
operation finishes (and we know whether the item is to be
removed after transfer or left as is)
- For the same reasons, "Drop nowhere to delete item" no longer
happens. Drag-and-drop is a failable operation and must not result
in data loss.
- As multiple actions are now allowed, we set the pointer icon
surface accordingly to the current operation.
This makes weston-dnd a better example of what applications usually
want to do here.
Changes since v2:
- Updated to behave alright-ish with version < 3.

Set up a keyboard grab during drag-and-drop, so we can translate
modifiers into preferred actions. The compositor chosen action
is stored in the current weston_data_source in order to make it
accessible to the source/offer at the time of calculating the new
action, but would conceptually be part of weston_drag.
The mapping has been made similar to what GTK+/QT usually do, the
shift key defaults to "move" and ctrl defaults to "copy".

After each buffer’s params were ready to be submitted to the
compositor, a roundtrip was done, which is wasteful since we can do it
only once after having queued all the params we want. Removing those
nested roundtrips also prevent the potentially dangerous side-effect of
calling callbacks for later events while previous events were still
