I've only seen this under travis, so I can't verify that this fixes it,
but it's certainly a bug which could cause that issue.

This is necessary to grad the their_unilateral/to-us outputs since
they aren't being harvested by `onchaind`
Signed-off-by: Christian Decker <decker.christian@gmail.com>
This is the scriptpubkey that onchaind spends all funds to, except for
the their_unilateral/to-us case, so we better recognize that address.

This is the only case in which we don't respend to a simple keyindex'd
pubkey, so we need to handle this for future spends.

We always arm the funding_lockin_cb, even if we don't need to. If we
have an short_channel_id already from the db, this was replacing it
and leaking the old one.

Since we panic when we see our root reorg out, even if we're not doing
anything yet, restoring the 100 block margin is the simplest fix.
Unfortunately this means adding a 100-block spacer in the tests, so things
don't get confused.

This is surprisingly simple. We set up the watches for funding tx
depth and the funding output, then if it's not onchain we ask gossipd
to reconnect.

Load the first block we're possibly interested in, then load the peers so
we can restore the tx watches, then finally replay to the current tip.

Eventually we want to save blockchain in db to avoid this scan, but
for the moment, we need to reload as far back as we may be interested in.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This gives us a lower bound on where funding tx could be.
In theory, it could be lower than this if we get a reorganization, but
in practice this is already a 1-block buffer (since we can't get into
current block, only the next one).

In the normal (peer-to-peer) path, the HTLC state prevents us fulfilling
twice, but this goes out the window with onchain HTLCs.
The actual assert which caught it was lightningd/pay.c:70 (payment_succeeded)
in the test_htlc_in_timeout test, after the next commit.
So add an assert earlier (in fulfill_our_htlc_out) and check in the
one caller where it can be true.

We used to load the new tip and work backwards until we joined up with
the previous tip. That consumed quite a lot of memory if there were
many blocks.
Instead, just poll on blocknum+1, and grab it once that succeeds. If
prev is different from what we expect (reorg), we free the current tip
and try again.
We could theoretically miss a reorg which is the same length (2 block
reorg with more work due to difficulty adjustment), but even if that
happened we'd catch up on the next block.

It definitely changes when we get a block, but it also changes between
blocks as mempool fills. So put it on its own timer.

It's just a sha256_double, but importantly when we convert it to a
string (in type_to_string, which is used in logging) we use
bitcoin_blkid_to_hex() so it's reversed as people expect.

I prefer the typesafety of specific functions, rather than having the
caller know that txids are traditionally reversed in bitcoin.
And we already have a bitcoin_txid_to_hex() function for this.

* Add port parsing support to parse_wireaddr. This is in preparation for storing
addresses in the peers table. This also makes parse_wireaddr a proper inverse of
fmt_wireaddr.
* Move parse_wireaddr to common/wireaddr.c this seems like a better place for
it. I bring along parse_ip_port with it for convenience. This also fixes some
issues with the upcoming ip/port parsing tests.

We set hout->key.id when channeld tells us what it is, but if channeld
dies before that we free the hout, and our destructor logs it:

Accuracy improvements:
1. We assumed the output was a p2wpkh, but it can be user-supplied now.
2. We assumed we always had change; remove this for wallet_select_all.
Calculation out-by-one fixes:
1. We need to add 1 byte (4 sipa) for the input count.
2. We need to add 1 byte (4 sipa) for the output count.
3. We need to add 1 byte (4 sipa) for the output script length for each output.
4. We need to add 1 byte (4 sipa) for the input script length for each input.
5. We need to add 1 byte (4 sipa) for the PUSH optcode for each P2SH input.
The results are now a slight overestimate (due to guessing 73 bytes
for signature, whereas they're 71 or 72 in practice).
