    Set 'routerlist' global to NULL before freeing it. · a9379d67

    There is other code that uses this value, and some of it is
    apparently reachable from inside router_dir_info_changed(), which
    routerlist_free() apparently calls.  (ouch!)  This is a minimal fix
    to try to resolve the issue without causing other problems.
    Fixes bug 31003. I'm calling this a bugfix on, where
    the call to router_dir_info_changed() was added to routerlist_free().
