The following command can be used to trigger these messages:
```
$ timeout 0.01 cli/lightning-cli connect [insert-syntactically-valid-peer-id-here] 123.123.123.123 # where 123.123.123.123 is unreachable
```
* Modifies invoice command to have the following format
invoice <msatoshi> <label> <desc> <?expiry> <?fallbackaddr>
* Adds support for Segwit bcrt1 addresses for withdraw
* Add test case for fallback address in invoice creation
* Create a common json_tok_address_scriptpubkey to be used
by invoice and withdraw commands.
We now keep a list of commands for the jcon instead of a simple
'current' pointer: the assertions become a bit more complex, but
the rest is fairly mechanical.

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.

Combining the two was just awkward, so it's clearer to have separate
functions. And we make the lower-level functions do the escaping.

The JSON-RPC spec specifies that if the request is unparseable we
should return an error with a NULL id. This is a bit more friendly
than slamming the door in the face.

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.

We move it into jsonrpc where it belongs, and make it fail the command.
This means it can tell us exactly what was wrong.

It's just a sha256_double, but importantly when we convert it to a
string (in type_to_string, which is used in logging) we use
bitcoin_txid_to_hex() so it's reversed as people expect.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
I prefer the typesafety of specific functions, rather than having the
caller know that txids are traditionally reversed in bitcoin.
And we already have a bitcoin_txid_to_hex() function for this.

The pay command in particular, attaches a reasonable number of

We have things which we don't keep a pointer to, but aren't leaks.
Some are simply eternal (eg. listening sockets), others cases are
io_conn tied to the lifetime of an fd, and timers which expire.

jsonrpc handlers usually directly call command_success or
command_fail; not doing that implies they're waiting for something
async.
Put an explicit call (currently a noop) there, and add debugging
checks to make sure it's used.

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.
