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.

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.

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.

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.

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.

These are now logically arrays of pointers. This is much more natural,
and gets rid of the horrible utxo array converters.

Commit a57a2dcb86 introduced a time_t
in routing.h. So also move the time.h include to the header. This
fixes the build on FreeBSD.

We were dropping these on the floor while checking for txout. So now
we add a map that holds announcements while we are checking.

We are wasting way too much time looking for announcements and updates
in the broadcast. We can just hint where to find the message to be
evicted and safe the traversal.

Adding channels that we are currently verifying to the map, and
skipping if we already have a channel at that position.

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:

We drop all but the first announcement, so any work that is done for a
channel that we already know is wasted. Pulling this up duplicates
some of the work but allows us to skip the costly txout check.
