ip: add address_is_specified() et.al., test
This means there's the mutually exclusive:
address_is_invalid() (really address_type() == NULL)
AF_UNSPEC==0
i.e., ip_address was initialized to zero
address_is_any()
AF_INET,AF_INET6; bytes==0;
IPv6 calls this the unspecified address; headers
mash up the terms ANY and UNSPECIFIED.
address_is_specified()
AF_INET,AF_INET6, bytes != 0
(any other AF_* value will abort)
A more correct term for "specified" might be "unicast" (as in unicast,
anycast, multicast), but then there's the problem of a "unicast"
address being indistinguishable from an "anycast" address (and in
pluto "any" refers to the zero address, ulgh).
