This is a rebased and combined patch for Tor support. It is extensively
reworked in the following patches, but the basis remains Saibato's work,
so it seemed fairest to begin with this.
Minor changes:
1. Use --announce-addr instead of --tor-external.
2. I also reverted some whitespace and unrelated changes from the patch.
3. Removed unnecessary ';' after } in functions.

1. Add special option where an empty host means 'wildcard for IPv4 and/or IPv6'
which means ':1234' can be used to set only the portnum.
2. Only add this protocol wildcard if --autolisten=1 (default)
and no other addresses specified.
3. Pass it down to gossipd, so it can handle errors correctly: in most cases,
it's fatal not to be able to bind to a port, but for this case, it's OK
if we can only bind to one of IPv4/v6 (fatal iff neither).

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
