[tracker] Do not make libtracker-module depend on tracker-indexer.

[Carlos Garnacho <carlosg src gnome org>]

commit bd2785055dbb1252100850cd4bc0463c9ce4826b
Author: Carlos Garnacho <carlosg gnome org>
Date:   Wed Apr 15 17:21:24 2009 +0200

    Do not make libtracker-module depend on tracker-indexer.
    
    * src/tracker-indexer/tracker-dbus.[ch]: Changed not to depend on
      tracker-indexer. Changed tracker_dbus_register_object() signature so all
      needed info is passed.
    * src/tracker-indexer/tracker-main.c: Pass all necessary info to
      tracker_dbus_register_object() from here. Add a name monitor hook so we stop
      the indexer if trackerd dissapears from DBus.
    * src/tracker-indexer/Makefile.am: Add tracker-dbus.c to libtracker-module, so
      it doesn't have deps on tracker-indexer.
