A log can have a default node_id, which can be overridden on a per-entry
basis. This changes the format of logging, so some tests need rework.

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

This was weird right from the start, so we just split the table into integers
and blobs, so each column has a well-defined format. It is also required for
postgres not to cry about explicit casts in the `paramTypes` array.

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.

We're about to change the API, so this makes the tests still work

And clean up some dev ones which actually happen (mainly by calling
channel_fail_permanent which logs UNUSUAL, rather than
channel_internal_error which logs BROKEN).

Because the call (wallet_extract_owned outputs) that prints that line can happen
_before_ or _after_ confirmation in block, adding `CONFIRMED` in the later.
make it a bit easier to track mutual channel closures by
adding broadcast txid to the listpeers billboard.
since lightningd manages the 'identity' of the closing tx we need
to send it back to closingd so it can update the billboard
appropriately.
In particular this matches the case of `their_unilateral/to_us` outputs, which
were missing their addresses so far.

We want to disallow using unconfirmed outputs by default, so making the
default 1 confirmation seems a good idea. This also matches `bitcoind`s
minimum confirmation requirement.
Arming however breaks some of our tests, so I used `minconf=0` for the
breaking tests and added a new test specifically for the `minconf` parameter
for `fundchannel`.

When we have multiple HTLCs with the same preimage and the same CLTV,
it doesn't matter what order we treat them (they're literally
identical). But when we offer HTLCs with the same preimage but
different CLTVs, the commitment tx outputs look identical, but the
HTLC txs are different: if we simply take the first HTLC which matches
(and that's not the right one), the HTLC signature we got from them
won't match. As we rely on the signature matching to detect the fee
paid, we get:
onchaind: STATUS_FAIL_INTERNAL_ERROR: grind_fee failed
So we alter match_htlc_output() to return an array of all matching
HTLC indices, which can have more than one entry for offered HTLCs.
If it's our commitment, we loop through until one of the HTLC
signatures matches. If it's their commitment, we choose the HTLC with
the largest CLTV: we're going to ignore it once that hits anyway, so
this is the most conservative approach. If it's a penalty, it doesn't
matter since we steal all HTLC outputs the same independent of CLTV.
For accepted HTLCs, the CLTV value is encoded in the witness script,
so this confusion isn't possible. We nonetheless assert that the
CLTVs all match in that case.

We set up HTLCs with the same preimage and both different and same
CLTVs in both directions, then make sure that onchaind is OK and that
the HTLCs are failed without causing downstream failure.
We do this for both our-unilateral and their-unilateral cases.

Create a second HTLC with a different CTLV but same preimage; onchaind

We extract the tx from the logs, and then we wait until that hits
the mempool. This is more reliable than 'sendrawtx' in the logs,
which might catch a previous sendrawtx; it's also more explicit
that we expect that tx exactly.

Manipulate fees via fake-bitcoin-cli. It's not quite the same, as
these are pre-smoothing, so we need a restart to override that where
we really need an exact change. Or we can wait until it reaches a
certain value in cases we don't care about exact amounts.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We don't respond to fee changes until we're locked in: make sure we catch
up at that point.
Note that we use NORMAL fees during opening, but IMMEDIATE after, so
this often sends a fee update. The tests which break, we set those
feerates to be equal.
This (sometimes) changes the behavior of test_permfail, as we now
get an immediate commit, so that is fixed too so we always wait for
that to complete.
