I've just updated the patches that got most changes. Commit log rewordings, and
other minor things like utf8 checks have been kept in the branch.

It is also worth noting I got the DnD icon working in the branch (last 3
patches there), although it involves some further hacks in GtkWindow to have it
use the GdkWindow/surface specified on wl_data_device_start_drag(). Would be
nice to have a better way to do this, although I guess that'll have to wait for
3.14. I feel this problem shares a lot with popup-window-on-subsurfaces though.

I've also been investigating the local drag issues, I figured local dragging is
broken until after the pointer leaves/enters the window because
wl_data_source_offer() should be called before wl_data_device_start_drag(),
something which is done inversely in the upper layers. As a result no targets
are offered, until the leave/enter provides a new wl_data_offer, so a bit
fruitless here so far.
