treewide: Improve robustness against sockaddrs of unexpected family

inany_from_sockaddr() expects a socket address of family AF_INET or
AF_INET6 and ASSERT()s if it gets anything else.  In many of the callers we
can handle an unexpected family more gracefully, though, e.g. by failing
a single flow rather than killing passt.

Change inany_from_sockaddr() to return an error instead of ASSERT()ing,
and handle those errors in the callers.  Improve the reporting of any such
errors while we're at it.

With this greater robustness, allow inany_from_sockaddr() to take a void *
rather than specifically a union sockaddr_inany *.
