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.
Changes since v1:
- Remove unneeded include. Remove extra newlines. Other minor
code fixes.

The policy in weston in order to determine the chosen DnD action is
deliberately simple, and is probably the minimals that any compositor
should be doing here.
Besides honoring the set_actions requests on both wl_data_source and
wl_data_offer, weston now will emit the newly added "action" events
notifying both source and dest of the chosen action.
The "dnd" client has been updated too (although minimally), so it
notifies the compositor of a "move" action on both sides.
Changes since v8:
- Add back wl_data_offer.source_actions emission, gone during last
code shuffling. Fix nits found in review.
Changes since v7:
- Fixes spotted during review. Add client-side version checks.

Changes since v3:
- Put data_source.action to use in the dnd client, now updates
the dnd surface like data_source.target events do.
Changes since v2:
- Split from DnD progress notification changes.

Weston now sends wl_data_source.dnd_drop_performed and .dnd_finished in
order to notify about the different phases of DnD.
wl_data_source.cancelled is also used as mentioned in the docs, being
emitted also on DnD when the operation is meant to fail (eg. source
and dest didn't agree on a mimetype).
The dnd demo is also fixed so the struct dnd_drag isn't leaked.

Those were found while working on simple-dmabuf-v4l, as found in the
next patch of this series.
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
being processed.

It is redundant to check x*alloc's return value for null pointers, since
they are guaranteed to either return non-NULL or terminate the program.
In cases where we memset the malloc'd memory to 0, we can more
efficiently use the xzalloc() routine. zalloc looks for opportunities
to return memory chunks that have already been zero'd out, so it can
provide better performance.
This patch addresses this warning, reported by Denis Denisov:
