[tor-commits] [tor/maint-0.2.2] Fix GETINFO config-text for private networks

    Fix GETINFO config-text for private networks
    
    In private networks, the defaults for some options are changed. This
    means that in options_validate(), where we're testing that the defaults
    are what we think they are, we fail. Use a workaround by setting a
    hidden configuration option _UsingTestingTorNetwork when we have altered
    the configuration this way, so that options_validate() can do the right
    thing.
    
    Fixes bug 2250, bugfix on 0.2.1.2-alpha (the version introducing private
    network options).
