8f17191099 param: upgraded json_tok_tok to advanced callback
This was a very simple change and allowed us to remove the special
`json_opt_tok` macro.

Moved the callback out of `common/json.c` to `lightningd/json.c` because the new
callbacks are dependent on `struct command` etc.
(I already started on `json_tok_number`)

My plan is to:
	1. upgrade json_tok_X one a time, maybe a PR for each one.
	2. When done, rename macros (i.e, remove "_tal").
	3. Remove all vestiges of the old callbacks
	4. Add new callbacks so that we no longer need json_tok_tok!
	   (e.g., json_tok_label, json_tok_str, json_tok_msat)

52303029aa fundchannel: cap 'all' at 2^24-1 satoshi.
The easiest way to do this is to play with the 'wallet_tx' semantics
and have 'amount' have meaning even when 'all_funds' is set.

Note that we change the string 'Cannot afford funding transaction' to
'Cannot afford transaction' as this code is also used for withdrawls.

d6048de100 json-rpc: Shutdown the JSON-RPC in the context of a DB transaction
This needs to be done separately from the rest of the daemon since we can
otherwise not make sure that it happens before the DB is freed and we might
still need the DN, and be running in a DB transaction, for some destructors to
run.

7f437715d5 Added error code parameter to command_fail
Until now, `command_fail()` reported an error code of -1 for all uses.
This PR adds an `int code` parameter to `command_fail()`, requiring the
caller to explicitly include the error code.

This is part of #1464.

The majority of the calls are used during parameter validation and
their error code is now JSONRPC2_INVALID_PARAMS.

The rest of the calls report an error code of LIGHTNINGD, which I defined to
-1 in `jsonrpc_errors.h`.  The intention here is that as we improve our error
reporting, all occurenaces of LIGHTNINGD will go away and we can eventually
remove it.

I also converted calls to `command_fail_detailed()` that took a `NULL` `data`
parameter to use the new `command_fail()`.

The only difference from an end user perspecive is that bad input errors that
used to be -1 will now be -32602 (JSONRPC2_INVALID_PARAMS).

af065417e1 gossipd: handle wildcard addresses correctly.
If we're given a wildcard address, we can't announce it like that: we need
to try to turn it into a real address (using guess_address).  Then we
use that address.  As a side-effect of this cleanup, we only announce
*any* '--addr' if it's routable.

This fix means that our tests have to force '--announce-addr' because
otherwise localhost isn't routable.

This means that gossipd really controls the addresses now, and breaks
them into two arrays: what we bind to, and what we announce.  That is
now what we return to the master for json_getinfo(), which prints them
as 'bindings' and 'addresses' respectively.

73cd009a4c gossipd/lightningd: use wireaddr_internal.
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

fe96fe10c7 Clean up network options.
It's become clear that our network options are insufficient, with the coming
addition of Tor and unix domain support.

Currently:

1. We always bind to local IPv4 and IPv6 sockets, unless --port=0, --offline,
   or any address is specified explicitly.  If they're routable, we announce.
2. --addr is used to announce, but not to control binding.

After this change:

1. --port is deprecated.
2. --addr controls what we bind to and announce.
3. --bind-addr/--announce-addr can be used to control one and not the other.
4. Unless --autolisten=0, we add local IPv4 & IPv6 port 9735 (and announce if they are routable).
5. --offline still overrides listening (though announcing is still the same).

This means we can bind to as many ports/interfaces as we want, and for
special effects we can announce different things (eg. we're sitting
behind a port forward or a proxy).

What remains to implement is semi-automatic binding: we should be able
to say '--addr=0.0.0.0:9999' and have the address resolve at bind
time, or even '--addr=0.0.0.0:0' and have the port autoresolve too
(you could determine what it was from 'lightning-cli getinfo'.

7767b68ee9 Removed redundancies in withdraw and fundchannel.
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.

a08bcfdbd3 jsonrpc: don't crash on multiple commands at once.
Once we read a command, we are supposed to io_wait until it finishes.
However, we are actually woken in two places: when it's complete
(which is correct), and when it's written out (which is wrong).

We don't care when it's written out, only when it's finished:
refactor to make json_done() free and NULL the old ->current,
rather than have the callers do it.  Now it's clear that it's
ready for both new output and new input.

b7acd93578 log: separate levels for IO directions, allow msg + io data.
We currently don't handle LOG_IO properly, and we turn it into a string
before handing it to the ->print function, which makes it ugly for
the case where we're using copy_to_parent_log, and also means in
that case we lose *what peer* the IO is coming from.

Now, we handle the io as a separate arg, which is much neater.
