    Don't clear out transient addressmap entries on HUP
    
    If you really want to purge the client DNS cache, the TrackHostExits
    mappings, and the virtual address mappings, you should be using NEWNYM
    instead.
    
    Fixes bug 1345; bugfix on Tor 0.1.0.1-rc.
    
    Note that this needs more work: now that we aren't nuking the
    transient addressmap entries on HUP, we need to make sure that
    configuration changes to VirtualAddressMap and TrackHostExits actually
    have a reasonable effect.
