tor-parallel-relay-conn/changes/bug14142-parse-virtual-addr

  o Minor bugfixes (client):
    - Check for a missing option value in parse_virtual_addr_network
      before asserting on the NULL in tor_addr_parse_mask_ports.
      This avoids crashing on torrc lines like
      Vi[rtualAddrNetworkIPv[4|6]] when no value follows the option.
      Bugfix on 0.2.3 (de4cc126cbb5 on 24 November 2012), fixes #14142.
      Patch by "teor".
