[tor-commits] [stem/master] Dropping support for port lists in descriptors

[atagar@xxxxxxxxxxxxxx]

commit dd220882e6c73863cc574ec4ba3833ee478314cb
Author: Damian Johnson <atagar@xxxxxxxxxxxxxx>

    Dropping support for port lists in descriptors
    
    The 'or-address' and 'a' descriptors supported comma separated lists of ports.
    However, as per spec commit 99a9587 tor has never supported this, and the spec
    no longer includes this capability.
