3d3d2ef9af gossipd: remove connectd functionality, enable connectd.
This patch guts gossipd of all peer-related functionality, and hands
all the peer-related requests to channeld instead.

gossipd now gets the final announcable addresses in its init msg, since
it doesn't handle socket binding any more.

lightningd now actually starts connectd, and activates it.  The init
messages for both gossipd and connectd still contain redundant fields
which need cleaning up.

There are shims to handle the fact that connectd's wire messages are
still (mostly) gossipd messages.

92d66a5451 gossipd: take connectd fd on initialization.
connectd has a dedicated fd to gossipd, so it can ask for a new gossip_fd
for a peer.

gossipd has a standalone routine to create a remote peer (this will
eventually be the only way gossipd creates a new peer).

For now lightningd creates a socketpair but doesn't run connectd, so
gossipd never sees any requests on this fd.

cf12130627 params: shortened names
This is a cosmetic change only. No functional changes.

I shortened the names of macros and changed param_parse() to param().

Also went through params.h with a fine-toothed comb and updated the comments
to reflect the current API.

I wanted to change the files:

	params.c -> param.c
	params.h -> param.h
	run-params.c -> run->param.c

but that confused `git diff` for params.h so its best left for another PR.

I'm keeping #1682 updated locally with all these changes.

6ff901d7b0 params: simplify lifetimes of params.
@wythe points out we don't need to keep the around now param_is_set()
is removed.  We can in fact go further and avoid marshalling them into
temporary objects at the caller altogether.

This means internally we have an array of struct param, rather than an
array of 'struct param *', which causes most of the noise in this
patch.

9f83a9ae4d params: make optional args do allocation for you.
This is a bit more natural, IMHO.  The only issue is that json_tok_tok is

4d1d0438e1 Typesafe callback system for parsing json
This is part of #1464 and incorporates Rusty's suggested updates from #1569.

See comment in param.h for description, here's the basics:

	unsigned cltv;
	const jsmntok_t *note;
	u64 msatoshi;
	struct param * mp;

	if (!param_parse(cmd, buffer, tokens,
			 param_req("cltv", json_tok_number, &cltv),
			 param_opt("note", json_tok_tok, &note),
			 mp = param_opt("msatoshi", json_tok_u64, &msatoshi),
			 NULL))
		return;

	if (param_is_set(mp))
		do_something()

There is a lot of developer mode code to make sure we don't make mistakes,
like trying to unmarshal into the same variable twice or adding a required param
after optional.

During testing, I found a bug (of sorts) in the current system.  It allows you
to provide two named parameters with the same name without error; e.g.:

	# cli/lightning-cli -k newaddr addresstype=p2sh-segwit addresstype=bech32
	{
		  "address": "2N3r6fT65PhfhE1mcMS6TtcdaEurud6M7pA"
	}

It just takes the first and ignores the second.  The new system reports this as an
error for now.  We can always change this later.

ef09961713 lightningd: rewrite tor service interaction to be synchronous, robust.
There's no reason to do this async, and far easier to follow using normal
read/write.

The previous parsing was deeply questionable, using substring searches
only, and relying on the fact that a single non-blocking read would get
the entire response.  This is changed to do (somewhat) proper parsing
using ccan/rbuf.

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.

1a4a59d221 common/daemon: common routines for all daemons.
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.

ef2a063169 utils: add a global tmpctx.
I did a brief audit of tmpctx uses, and we do leak them in various
corner cases.  Fortunely, all our daemons are based on some kind of
I/O loop, so it's fairly easy to clean a global tmpctx at that point.

This makes things a bit neater, and slightly more efficient, but also
clearer: I avoided creating a tmpctx in a few places because I didn't
want to add another allocation.  With that penalty removed, I can use
it more freely and hopefully write clearer code.

a2c6ec6c9b lightningd: use tal_link for log_book.
BackgroundL Each log has a log_book: many logs can share the same one,
as each one can have a separate prefix.

Testing tickled a bug at the end of this series, where subd was
logging to the peer's log_book on shutdown, but the peer was already
freed.  We've already had issues with logging while lightningd is
shutting down.

There are times when reference counting really is the right answer,
this seems to be one of them: the 'struct log' share the 'struct
log_book' and the last 'struct log' cleans it up.
