55d962046b Rename (almost) all destructors to destroy_<type>.
We usually did this, but sometimes they were named after what they did,
rather than what they cleaned up.

There are still a few exceptions:
1. I didn't bother creating destroy_xxx wrappers for htable routines
   which already existed.
2. Sometimes destructors really are used for side-effects (eg. to simply
   mark that something was freed): these are clearer with boutique names.
3. Generally destructors are static, but they don't need to be: in some
   cases we attach a destructor then remove it later, or only attach
   to *some* cases.  These are best with qualifiers in the destroy_<type>
   name.

e76a0b4ddc gossipd: fix race where we can handoff peer with bad cryptostate.
DEBUG:root:lightningd(16333): 2018-02-08T02:12:21.158Z lightningd(8262): lightning_openingd(0382ce59ebf18be7d84677c2e35f23294b9992ceca95491fcf8a56c6cb2d9de199): Failed hdr decrypt with rn=2

We only hand off the peer if we've not started writing, but that was
insufficient: we increment the sn twice on encrypting packet, so there's
a window before we've actually started writing where this is now
wrong.

The simplest fix is only to hand off from master when we've just written,
and have the read-packet path simply wake the write-packet path.

d5effcb961 test_lightning: fix race on testing, esp. test_closing_different_fees.
We get intermittant failure: WIRE_UNKNOWN_NEXT_PEER (First peer not ready)
because CHANNELD_NORMAL and actually telling gossipd that the channel
is available are distinct things: we need both.

(For test_closing_different_fees, we were testing CHANNELD_NORMAL on
the peer, not on l1, too).

But we may also directly send the announcement sigs if the height is
sufficient, so the simplest is to unify the messages.

fd498be7ca status: generate messages rather than marshal/unmarshal manually.
Now we have wirestring, this is much more natural.  And with the
24M length limit, we needn't be so concerned about dumping 64k peer
messages in hex.

8fcb45c1b2 routing: use marshalled short_channel_id, not string as tag for channel_announce
We use this technique for the other tags, so use it here too.

This was drawn to my attention when I made more than 10 channels in a
block, and the string changed length:

3a42e52bcd gossip: Fix a memcmp with unset memory in broadcast queue
`tal_fmt` overallocates the returned string under some circumstances,
meaning that the trailer of the formatted string is unset, but still
considered in `tal_len`. The solution then is to truncate the
formatted string to the real string length. Only necessary here, since
we mix strings and `tal_len`.
