Use less memory for ip_addr in port_reason.

Browse Source 
This was a sockaddr_storage, which is 128 bytes. This is a lot for a
structure that is part of Port. It is now a union of sockaddr_in and
sockaddr_in6, which is 28 bytes. A new set_ip_addr method sets the union
from a sockaddr_storage, where plain assignment was used before.

The sockaddr_storage was introduced in r23778, the first big IPv6 merge.
