data-device: Implement DnD progress notification
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.

Changes since v6:
- Add client-side version checks. Minor code shuffling.
Changes since v5:
- Dissociate source and offer after cancel. Updated to
apply on top of c9f8f8a7f.
Changes since v4:
- Make wl_data_offer.finish with the wrong state an error.
Changes since v3:
- Fixed wl_data_source.dnd_finished vs cancelled emission on
when interoperating with version < 3 drag destinations.
Changes since v2:
- Handle wl_data_offer.finish. Fixed commit log inconsistencies.
Added version checks. Spaces vs tabs fixes. Fixed resource
versioning.
Changes since v1:
- Updated to protocol v2.
