lisa neigut a9d0550cf4 common: pull out scriptPubkey address method
We're going to need this for P2WSH scripts. pull it out into
a common file plus adopt the sanity checks so that it will allow for
either P2WSH or P2WPKH (previously only encoded P2WPKH scripts)

Rusty Russell 220449e1cd ccan: import ccan/json_out and ccan/json_escape.
These are generalized from our internal implementations.

The main difference is that 'struct json_escaped' is now 'struct
json_escape', so we replace that immediately.

The difference between lightningd's json-writing ringbuffer and the
more generic ccan/json_out is that the latter has a better API and
handles escaping transparently if something slips through (though
it does offer direct accessors so you can mess things up yourself!).

Take into account the fee we'd have to pay if we're the funder, and
also drop to 0 if the amount is less than the smallest HTLC the peer

Encapsulating the peer state was a win for lightningd; not surprisingly,
it's even more of a win for the other daemons, especially as we want

Rusty Russell b4455d517c common/node_id: new type.
Node ids are pubkeys, but we only use them as pubkeys for routing and checking
gossip messages.  So we're packing and unpacking them constantly, and wasting
some space and time.

This introduces a new type, explicitly the SEC1 compressed encoding
(33 bytes).  We ensure its validity when we load from the db, or get it
from JSON.  We still use 'struct pubkey' for peer messages, which checks
validity.

Christian Decker f8f76e3d31 plugin: Add hook registration
I might have gone a bit overboard with the type-checking, but
typesafe_cb_cast is quite nice to use, so why not. The macro to
register a new hook encapsulates the entire flow from param
serialization, to dispatch, parsing and callback dispatch in one
bundle. I was tempted to have the callback outside of the
registration, but it's unlikely that we'll have two calls to the same
hook with different callbacks.

Rusty Russell e17f69ce2d json_stream: disentangle JSON handling from command.
We promote 'struct json_stream' to contain the membuf; we only attach
the json_stream to the command when we actually call
json_stream_success / json_stream_fail.

This means we are closer to 'struct json_stream' being an independent
layer; the tests are already modified to use it directly to create
JSON.

This is also the first step toward re-enabling non-serial command
execution.

This is a bit of overkill now that we simply accumulate the entire

streamed responses it allows us to have a single command that has
exclusive access to the out direction of the JSON-RPC connection.

Rusty Russell 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.

Mark Beckwith 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.

Rusty Russell 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.
