Rusty Russell	c8c3294a23	json-invoice: add routeboost, warnings. We split json_invoice(), as it now needs to round-trip to the gossipd, and uniqueness checks need to happen after gossipd replies to avoid a race. For every candidate channel gossipd gives us, we check that it's in state NORMAL (not shutting down, not still waiting for lockin), that it's connected, and that it has capacity. We then choose one with probability weighted by excess capacity, so larger channels are more likely. As a side effect of this, we can tell if an invoice is unpayble (no channels have sufficient incoming capacity) or difficuly (no online channels have sufficient capacity), so we add those warnings.

json-invoice: add routeboost, warnings.

We split json_invoice(), as it now needs to round-trip to the gossipd,
and uniqueness checks need to happen *after* gossipd replies to avoid
a race.

For every candidate channel gossipd gives us, we check that it's in
state NORMAL (not shutting down, not still waiting for lockin), that
it's connected, and that it has capacity.  We then choose one with
probability weighted by excess capacity, so larger channels are more
likely.

As a side effect of this, we can tell if an invoice is unpayble (no
channels have sufficient incoming capacity) or difficuly (no *online*
channels have sufficient capacity), so we add those warnings.
