data-device: implement drags with no data source for self-dnd

Browse source 
Properly handle a drag with no data source, i.e., don't crash and send
events only to the client that initiated the drag. This way a client can
do self drag and drop without offering anything to other clients.

<request name="start_drag">
<description summary="start drag and drop operation">
This request asks the compositor to start a drag and drop
operation on behalf of the client. The source argument is the
data source that provides the data for the eventual data
transfer. The origin surface is the surface where the drag
originates and the client must have an active implicit grab
that matches the serial. The icon surface is an optional
(can be nil) surface that provides an icon to be moved around
with the cursor. Initially, the top-left corner of the icon
surface is placed at the cursor hotspot, but subsequent
surface.attach request can move the relative position.

The source argument is the data source that provides the data
for the eventual data transfer. If source is NULL, enter, leave
and motion events are sent only to the client that initiated the
drag and the client is expected to handle the data passing
internally.
