[tor-commits] [metrics-db/master] Check bridge stats in sanitized bridge descriptors.

commit 5986188f93d897ba58dc56ad16d761b986471717

    Check bridge stats in sanitized bridge descriptors.
    
    Make sure that there's always a bridge-stats-end line preceding the
    bridge-ips line.
    
    We should add more such checks in the future.  This is probably something
    to implement in metrics-lib once it's more stable.
