libunwind does not accept a NULL parameter for the error callback. It
will simply call into the NULL pointer. So add an error callback.
This makes the crash output somewhat more sensible on FreeBSD, where
there is no libunwind stack trace available:

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.

Maintaining it was always fraught, since the command could go away
if the JSON RPC died. Most recently, it was broken again on shutdown
(see below).
In future we may allow pay commands to block on previous payments, so
it won't even be a 1:1 mapping. Generalize it: keep commands in a
simple list and do a lookup when a payment fails/succeeds.

It was taking over 10 minutes under valgrind, causing Travis to time it out.
This shrinks it to its essential tests, and also batches.

This is a transitional patch so we can still close channels cleanly;
for want of a better option, I hooked it into --deprecated-apis.

This follows the proposal to make the funder send the first offer.
The dual loops are because there's initially very little restriction
on the amounts, then once they're first established they tighten as
necessary.

We shouldn't fail negotiation just because they exceeded what we thought
fair: we're better off as long as it's actually <= final commitment fee.
