From: Cong Wang <amwang@redhat.com>
Introduce a generic IP address type, union inet_addr, so that
subsystems don't have to use their own definitions. Because
netpoll already defines union inet_addr, just move it to global.
Some of the helper functions will be used by VXLAN IPv6 code too.
This patch also reuses the "%pIS" specifier, to make it accept
union inet_addr instead of struct sockaddr.

From: Cong Wang <amwang@redhat.com>
sctp has its own union sctp_addr which is nearly same
with the generic union inet_addr, so just convert it
to the generic one.
Sorry for the big patch, it is not easy to split it. Most
of the patch simply does s/union sctp_addr/union inet_addr/
and some adjustments for the fields.
The address family specific ops, ->cmp_addr(), ->is_any() etc.,
are removed, since we have generic helpers, they are unnecessary.
