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).
Closes: #1323

At least say whether we failed to connect at all, or failed cryptographic
handshake, or failed reading/writing init messages.
The errno can be "Operation now in progress" if the other end closes the
socket on us: this happens when we handshake with the wrong key and it
hangs up on us. Fixing this would require work on ccan/io though.

Now we have them, let's use them. I missed one case deliberately, since
that causes merge conflicts when I replace it in a following patch.

And nail "make check-source" to that specific version (which is a commit id,
not a branch name, so needs a different syntax for git).

In future it will have TOR support, so the name will be awkward.
We collect the to/fromwire functions in common/wireaddr.c, and the
parsing functions in lightningd/netaddress.c.

We need to derive this from the fd when they connect in, but we already
know it if we're connecting out.
We want this so we can tell (in next few patches) master the peer's address.
