For the moment, this is a straight handing of current parameters through
from master to the gossip daemon. Next we'll change that.

This is simply the code to set up the automatic hidden service, so move
it into lightningd.
I removed the undefined parse_tor_wireaddr, and added a parameter name
to the create_tor_hidden_service_conn() declaration for update-mocks.

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.

It does all the other address handling, do this too. It also proves useful
as we clean up wildcard address handling.

No new functionality, just a continuation of my work toward completing #665.
I removed the common members of `struct withdrawal` and `struct fund_channel`
and placed them in a new `struct wallet_tx`. Then it was fairly straightforward
to reimplement the existing code in terms of `wallet_tx`.
Since I made some structural changes I wanted to get this approved before I
go any farther.
Added 'all' to fundchannel help message.
These were so far only used for bolt11 construction, but we'll need them for the
DNS seed as well, so here we just pull them out into their own unit and prefix
them.

In particular, the main daemon and subdaemons share the backtrace code,
with hooks for logging.
The daemon hook inserts the io_poll override, which means we no longer
need io_debug.[ch]. Though most daemons don't need it, they still link
against ccan/io, so it's harmess (suggested by @ZmnSCPxj).
This was tested manually to make sure we get backtraces still.

Transaction filters are strongly related to the wallet, this move just
makes it a bit more explicit.

We also fold opening_got_hsm_funding_sig() into the caller; it was
previously a callback before we decided to always use the HSM
synchronously.

Several daemons (onchaind, hsm) want to use the status messages, but
don't communicate with peers. The coming changes made them drag in
more code they didn't need, so instead we have a different
non-overlapping type.
We combine the status_received_errmsg and status_sent_errmsg
into a single status_peer_error, with the presence or not of the
'error_for_them' field indicating direction.
We also rename status_fatal_connection_lost() to
peer_failed_connection_lost() to fit in.

And now we can finally do the db upgrade to remove any OPENINGD
channels once, since we never put them back.

Much like the database; peer contains id, address, channel contains
per-channel information. Where we create a channel, we always create
the peer too.
For the moment, peer->log and channel->log coexist side-by-side, to
reduce some of the churn.
Note that this changes the API to dev-forget-channel: if we have more
than one channel, we insist they specify the short-channel-id.

Now we have wirestring, this is much more natural. And with the
24M length limit, we needn't be so concerned about dumping 64k peer
messages in hex.

This is a primitive mark-and-sweep-style garbage detector. The core is
in common/ for later use by subdaemons, but for now it's just lightningd.
We initialize it before most other allocations.
We walk the tal tree to get all the pointers, then search the `ld`
object for those pointers, recursing down. Some specific helpers are
required for hashtables (which stash bits in the unused pointer bits,
so won't be found).
There's `notleak()` for annotating things that aren't leaks: things
like globals and timers, and other semi-transients.

Change all calls to use the correct serialization and deserialization

This is mainly used to filter for transactions that may be of interest
to us, i.e., whether one of our keys is the recipient. It currently
does onyl simple scriptpubkey checks, but will eventually be extended
to use bloomfilters and add more sophisticated checks.
For now the goal is to speed up the processing of blocks during startup.

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.

Now the flow is much simpler from a lightningd POV:
1. If we want to connect to a peer, just send gossipd `gossipctl_reach_peer`.
2. Every new peer, gossipd hands up to lightningd, with global/local features
and the peer fd and a gossip fd using `gossip_peer_connected`
3. If lightningd doesn't want it, it just hands the peerfd and global/local
features back to gossipd using `gossipctl_handle_peer`
4. If a peer sends a non-gossip msg (eg `open_channel`) the gossipd sends
it up using `gossip_peer_nongossip`.
5. If lightningd wants to fund a channel, it simply calls `release_channel`.
Notes:
* There's no more "unique_id": we use the peer id.
* For the moment, we don't ask gossipd when we're told to list peers, so
connected peers without a channel don't appear in the JSON getpeers API.
* We add a `gossipctl_peer_addrhint` for the moment, so you can connect to
a specific ip/port, but using other sources is a TODO.
* We now (correctly) only give up on reaching a peer after we exchange init
messages, which changes the test_disconnect case.

This fixes the only case where the master currently has to write directly
to the peer: re-sending an error. We make gossipd do it, by adding
a new gossipctl_fail_peer message.

In particular, the main daemon needs to pass it about (marshal/unmarshal)

Also, we split the more sophisticated json_add helpers to avoid pulling in
everything into lightning-cli, and unify the routines to print struct
short_channel_id (it's ':', not '/' too).

To avoid everything pulling in HTLCs stuff to the opening daemon, we
split the channel and commit_tx routines into initial_channel and
initial_commit_tx (no HTLC support) and move full HTLC supporting versions
