	Fix the use of lazy positioning, and the saving of metadata for
	lazily-positioned icons.  Fixes
	https://bugzilla.novell.com/show_bug.cgi?id=155337 and
	https://bugzilla.novell.com/show_bug.cgi?id=174766.

	* src/file-manager/fm-icon-view.c (file_has_lazy_position): Only
	desktop icon files (not "real" files) have lazy positions.  Don't
	consider whether the directory is loading; this is not the right
	place to check that.
	(fm_icon_view_begin_loading): Tell the icon container that we
	just started reloading.
	(fm_icon_view_end_loading): Tell the icon container that we
	finished loading.

	* libnautilus-private/nautilus-icon-private.h
	(NautilusIconContainerDetails): New flag "is_reloading".

	* libnautilus-private/nautilus-icon-container.h: New prototype for
	nautilus_icon_container_set_is_reloading().

	* libnautilus-private/nautilus-icon-container.c
	(nautilus_icon_container_set_is_reloading): New function; sets an
	is_reloading flag in the icon container.
	(icon_set_position): Clear icon->has_lazy_position, since the icon
	will be well-positioned once this function exits.
	(finish_adding_new_icons): Do not ignore already-placed lazy
	position icons when filling the placement grid!  Save the value of
	icon->has_lazy_position before calling assign_icon_position().
	Since that function may call icon_set_position() (which will clear
	the flag), we need to keep the original value of the flag.
	(finish_adding_new_icons): Don't clear icon->has_lazy_position
	here; let icon_set_position() do it.
	(finish_adding_new_icons): Emit the icon_position_changed signal
	so that the parent knows that we moved an icon under it.  This has
	the effect of updating/preserving the position metadata for
	has_lazy_position icons.
