Just a small cleanup of the indentation code, so we don't have to reformat all
the issue reports to become readable. This is much closer to what `jq` or
`json_pp` spit out and doesn't have those infinitely long lines.

We can have more than one; eg we might offer both bech32 and a p2sh
address, and in future we might offer v1 segwit, etc.

This is probably covered by our "channel capacity" heuristic which
requires the channel be significant, but best to be explicit and sure.

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.

I didn't convert all tests: they can still use a standalone context.
It's just marginally more efficient to share the libwally one for all
our daemons which link against it anyway.

The overflow check `mul_overflows_s64(int64_t, int64_t)` overflows.
Since this is an signed integer overflow this triggers UB, which
in turn means that we cannot trust the check.
Luckily mul_overflows_s64(int64_t, int64_t) is unused. Removing it.
We don't handle \u, since we assume everyone sane is using UTF-8. We'd
still have to reject '\u0000' and maybe other weird cases if we did.

If we're going to simply take() a pointer, don't allocate it off a random
object. Using NULL makes our intent clear, particularly with allocating
packets we're going to take() onto a queue.

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.

Now it just returns true if it queued something. This allows it
to queue multiple packets, and lets it share code paths with other code
in future patches.

As we add more features, the current code is insufficient.
1. Keep an array of single feature bits, for easy switching on and off.
2. Create feature_offered() which checks for both compulsory and optional
variants.
3. Invert requires_unsupported_features() and unsupported_features()
which tend to be double-negative, all_supported_features() and
features_supported().
4. Move single feature definition from wire/peer_wire.h to common/features.h.

We didn't get the entire thing in the parent when gossipd crashed: stderr
is suitable for these I think.

Looking at an example log from #968, 288612 of 289244 lines were simply

We always hand in "NULL" (which means use tal_len on the msg), except
for two places which do that manually for no good reason.

Because peer_failed would previously drop the connection, we had a
special 'negotiation_failed' message which made the master hand it
back to gossipd. We don't need that any more.
This also meant we no longer need a special hook in read_peer_msg
for openingd to send this message.
