Always associate a drag context with a GdkDisplay and use that when
getting a cursor for a given action.
If we don't do this, dragging on a window that doesn't use the default
display will make us use cursors from the wrong display.

Add a variant of gdk_drag_begin that takes the start position
in addition to the device. All backend implementation have been
updated to accept (and ignore) the new arguments.
Subsequent commits will make use of the data in some backends.
This just runs:
for i in *.[ch]; do
sed -i s/DisplayX11/DisplayBroadway/g $i;
sed -i s/PrivateX11/PrivateBroadway/g $i;
sed -i s/ImplX11/ImplBroadway/g $i;
sed -i s/KeymapX11/KeymapBroadway/g $i;
sed -i s/ScreenX11/ScreenBroadway/g $i;
sed -i s/GdkX11Monitor/GdkBroadwayMonitor/g $i;
sed -i s/_X11/_BROADWAY/g $i;
sed -i s/x11/broadway/g $i;
done
