This prevents a crash in the current views code when running under

crashes because the views using application does not have an X11
connection.

I was hoping that I wouldn't have to commit this stub first, but it turns out I
have to to make progress. As is, without replacing the OSExchangeData::Provider,
we crash as soon as we try to drag anything because we attempt to talk to X11
(via aura).

This stub rejects everything and doesn't perform any work, but fixes a crash on
ToT.

LGTM
