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.

`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`.

We need to make sure all the updates are known to gossip. Since
one is the local update, we change that message to look the same.

Otherwise, we otherwise end up with out-of-order updates
(ie. preceeding announcements).
I assume that is because of the locally-inserted connections.

This is done it two parts, since we have to ask the main daemon to do
the lookup for us.
If this becomes a bottleneck, we can have a separate daemon, or even
an RPC pipe to bitcoind ourselves.

Our handling of SIGPIPE was incoherent and inconsistent, and we had much
cut & paste between the daemons. They should *ALL* ignore SIGPIPE, and
much of the rest of the boilerplate can be shared, so should be.

Sometimes we could get into a situation in which we knew the channel
but couldn't find it via the short_channel_id. That'd result in a
replacement which triggered an assert.

The use of status_failed() requires a stubs update, which fails
with unnamed parameters, so tweak the status.h header as well.
