gossipd: take over address determination, from master. It does all the other address handling, do this too. It also proves useful as we clean up wildcard address handling. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

gossipd/lightningd: use wireaddr_internal. This replacement is a little menial, but it explicitly catches all the places where we allow a local socket. The actual implementation of opening a AF_UNIX socket is almost hidden in the patch. The detection of "valid address" is now more complex: p->addr.itype != ADDR_INTERNAL_WIREADDR || p->addr.u.wireaddr.type != ADDR_TYPE_PADDING But most places we do this, we should audit: I'm pretty sure we can't get an invalid address any more from gossipd (they may be in db, but we should fix that too).

gossipd: handle wildcard addresses correctly. If we're given a wildcard address, we can't announce it like that: we need to try to turn it into a real address (using guess_address). Then we use that address. As a side-effect of this cleanup, we only announce *any* '--addr' if it's routable. This fix means that our tests have to force '--announce-addr' because otherwise localhost isn't routable. This means that gossipd really controls the addresses now, and breaks them into two arrays: what we bind to, and what we announce. That is now what we return to the master for json_getinfo(), which prints them as 'bindings' and 'addresses' respectively. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
