We were checking against hardcoded hrp and prefixes. Now we parametrize via
the chainparams.

It's generally clearer to have simple hardcoded numbers with an
#if DEVELOPER around it, than apparent variables which aren't, really.
Interestingly, our pruning test was always kinda broken: we have to pass
two cycles, since l2 will refresh the channel once to avoid pruning.
Do the more obvious thing, and cut the network in half and check that
l1 and l3 time out.

Refactored the weighted-reservoir-sampling algo to make it more straightforward.
It now uses the excess as fraction of capacity as weight. This favors channels that
are more _relatively_ unbalanced to be used for incoming payment.
Now passes test_invoice_routeboost_private() when using max fundamount=16777215.
Funder can't spend the fee it needs to pay for the commitment transaction:
we were not converting to millisatoshis, however!
This breaks our routeboost test, which no longer has sufficient funds
to make payment.

We don't create unannouncable channels, but other implementations can.
Not only is it rude to expose these via invoices, it's probably not
useable anyway.

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.

We're about to slow down the invoice rpc (esp. under valgrind), which
breaks the delicate timing of the autocleaninvoice test.
Change that so the autocleaner (and timestamp) starts after the invoices
are added.
