And on channel_fail_permanent and closing (the two places we drop to
chain), we tell gossipd it's no longer important.

d822ba1ee accidentally removed this case, which is important: if the
other side didn't get our final matching closing_signed, it will
reconnect and try again. We consider the channel no longer "active"
and thus ignore it, and get upset when it send the
`channel_reestablish` message.
We could just consider CLOSINGD_COMPLETE to be active, but then we'd
have to wait for the closing transaction to be mined before we'd allow
another connection.
We can't special case it when the peer reconnects, because there
could be (in theory) multiple channels for that peer in CLOSINGD_COMPLETE,
and we don't know which one to reestablish.
So, we need to catch this when they send the reestablish, and hand
that msg to closingd to do negotiation again. We already have code
to note that we're in CLOSINGD_COMPLETE and thus ignore any result
it gives us.

Also report tx and txid, and whether we closed unilaterally or
bilaterally, if we could close the channel.
Also make a manpage.

We had an intermittant test failure, where the fee we negotiated was
further from our ideal than the final commitment transaction. It worked
fine if the other side sent the mutual close first, but not if we sent
our unilateral close first.

Really, if we're prepared to negotiate it, we should be prepared to
accept it ourselves. Simply take the cheapest tx which is above our
minimum.

This simplifies things, and means it's always in the database. Our
previous approach to creating it on the fly had holes when it was
created for onchaind, causing us to use another every time we
restarted.

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.
