Comment(by rransom):

 00:19 < wanoskarnet> re branch "short_address_rep": any explicitly non
 inited tor_addr_t structs will have AF_INET6 family, that hides exist
 family related bugs.

 The all-zero IPv6 address is used as `in6addr_any` by the IPv6 code, so if
 we use that as a special ‘uninitialized’ value of `tor_addr_t`, we'll have
 to do some careful fiddling to be able to specify `in6addr_any` in certain
 inputs and pass it to networking functions.
