	Fix http://bugzilla.gnome.org/show_bug.cgi?id=330298 once again
	(desktop icons overlap when placing a volume icon, and in various
	other situations):

	* libnautilus-private/nautilus-icon-container.c (icon_set_position):
	Clear icon->has_lazy_position, since the icon will be
	well-positioned once this function exits.
	(finish_adding_new_icons): Don't clear icon->has_lazy_position
	here, since it is now done in icon_set_position().  Emit the
	"icon-position-changed" signal so that the upstream code will save
	the final position for icons which were semi-positioned.
	(finish_adding_new_icons): Remember the original
	icon->has_lazy_position before calling assign_icon_position();
	later, if the icon was to be lazily positioned, add it to the
	semi_position_icons list.  Previously we were ignoring
	semi-positioned icons when populating the placement grid; that's
	why overlaps would happen.

	* src/file-manager/fm-icon-view.c (file_has_lazy_position): Also
	use lazy positioning for drives, not just volumes.
