The tor proxy might want auth 0x2 or answer what ever not defined
in https://tools.ietf.org/html/rfc1928.
Changelog-Fixed: TOR: We don't send any further request if the return code of connect is not zero or error.
Signed-off-by: Saibato <saibato.naga@pm.me>
For example:
"Tor connect out for host example.com error: 4 "
becomes:
"Error connecting to example.com: Tor server reply: host unreachable"
Also clarify the error:
"Connected out for example.com error"
to:
"Connected out for example.com error: authentication required"
because the only reason it could have failed is that the Tor socks5
server did not like any of our proposed auth methods and we only
proposed "no auth".
Changelog-None
This is ignored in subdaemons which are per-peer, but very useful for
multi-peer daemons like connectd and gossipd.

@renepickhardt: why is it actually lightningd.c with a d but hsm.c without d ?
And delete unused gossipd/gossip.h.

Good for debugging (you have to send SIGUSR1 to lightning_gossipd to turn
it on though, and --log-level=io on the lightningd cmdline to have it
output IO messages by default).
I also noticed that io_tor_connect_after_req_host() does a useless
test on reach->buffer[0] after it's *written*: remove it.

Previously it converted the wireaddr to a string internally: to support
unresolved names we need that done externally.
We actually tell the SOCKS5 proxy to do a domain lookup already, even
though we give use IP/IPv6 address, so this change is sufficient to
support connect-by-name.
Note replacement of assert() with an explicit case statement, which
has the benefit that the compiler complains when we add new
ADDR_INTERNAL types.

This means it will effect connect commands too (though it's too
late to stop DNS lookups caused by commandline options).
We also warn that this is one case where we allow forcing through Tor
without a proxy set: it just means all connections will fail.

1. Only force proxy use if we don't announce any non-TOR address.
There's no option to turn it off, so this makes more sense.
2. Don't assume we want an IPv4 socket to reach proxy, use the family
from the struct addrinfo.

Instead of storing a wireaddr and converting to an addrinfo every
time, just convert once (which also avoids the memory leak in the
current code).

All gossipd needs from common/tor is do_we_use_tor_addr(), so move
that and the rest of the tor-specific handshake code into gossip/tor.c
