[tor-commits] [stem/master] Stop generating too-long nicknames

commit 7d157f9ad852b3f2020df45fb35a18accaef23fa
Author: Taylor Yu <catalyst@xxxxxxxxxxxxxx>

    Stop generating too-long nicknames
    
    Some platforms have sys.maxint large enough that the random router
    nicknames were too long (especially for BridgeDescriptor).  Factor out
    the random nickname generation into _random_nickname() and use it
    consistently.
