[tor-commits] [bridgedb/master] 5947 - Parse "a" lines from networkstatus

[aagbsn@xxxxxxxxxxxxxx]

commit 677272c11ea1a4b86fb143a12a76d03a6384b032

    5947 - Parse "a" lines from networkstatus
    
    The "a" lines have been tested by the Bridge Authority.
    The or-addresses in the bridge descriptors have not.
    
    This fix makes BridgeDB read or-addresses from the networkstatus
    instead of the bridge descriptors
