    Setting zero ports to None in server descriptors
    
    When writing the server descriptor parser I faithfully translated zero ports as
    zero because I wanted users to be able to differentiate between 'malformed' and
    'zero' when validation was disabled. However, on reflection I don't really care
    about catoring to non-validation use cases.
    
    Ravi made the router status entries interpret a zero port as being None which
    makes perfect sense - zero means that the port doesn't exist. Doing this for
    the server descriptors too.
