[gtk+/places-sidebar] Replace nautilus_window_set_initiated_unmount() with an initiated-unmount signal

[Federico Mena Quintero <federico src gnome org>]

commit 81184518610e58256e24643823a0430badc3edd0
Author: Federico Mena Quintero <federico gnome org>
Date:   Mon Oct 3 11:51:46 2011 -0500

    Replace nautilus_window_set_initiated_unmount() with an initiated-unmount signal
    
    This signal just carries a boolean initiated_unmount argument, which
    is meant to say True when the unmount/eject starts, and False when
    the operation finishes.
    
    We may want to rename all of this to unmount_started / stopped, etc.
    I don't know if the caller needs to know about the mount_op in question,
    or if it can be inferred from what the caller knows to be the current
    shown location on the GtkPlacesSidebar.
