Simplification of the offset calculation to use the rescan parameter, and rename
of `wallet_first_blocknum`. We now use either relative rescan from our last
known location, or absolute if a negative rescan was given. It's all handled in
a single location (except the case in which the blockcount is below our
precomputed offset), so this should reduce surprises.

Careful log examination revealed that we were generating a block before one
of the mutual close txs had entered the mempool. This is rare because it
means that both peers have to be too slow.

I had a weird failure which was caused by an unexpected disconnect and
reconnecct. Since we are prersistend and recover from these, they can
slip through our tests; most tests don't involve reconnection, so we
need to catch this explicitly.
For the connect() helper, we always suppress reconnection; tests which
want it all want other options so don't use this helper anyway. (Actually,
after I said that, test_closing_while_disconnected was added when I
rebased, which did require it, so I had to open-code that one).

Mixing the test into the existing test allows us to reduce the execution, but
adds a bit of complexity, so I added two small helpers.

This fixes the root cause of https://github.com/ElementsProject/lightning/issues/1212
where we deleted the payment because we wanted to retry, then retry failed
so we had an (old) HTLC without a matching payment. We then fed that
HTLC to onchaind, which tells us it's missing, and we try to fail the
payment and deref a NULL pointer.

We say "in N blocks" but we actually mean "N blocks after this tx" which is
actually N-1 or less. Change wording and tighten tests which misunderstood
this.
Also, the 'assert not l1.daemon.is_in_log('onchaind complete, forgetting peer')'
are unlikely to work until the daemon has actually seen the block, so add
sync_blockheight before all of those.
These changes reveal some sloppy testing, which we fix.

With the following patch applied, we could clearly see onchaind try to
broadcast the timeout tx one block too early:
sendrawtx exit 26, gave error code: -26?error message:?non-final (code 64)?
This is because of an out-by-one error in calculating the relative
depth required, since the out->tx_blockheight is already 1 before the
current block.

This was revealed in #1114; onchaind isn't actually completely idempotent
due to fee changes (and the now-fixed change in keys used).
This triggers the bug by restarting with different fees, resulting in
onchaind not recognizing its own proposal:

We currently give them a free pass. The simplest fix is to give them
an old timestamp on initialization.
We still skip unannounced channels, on the assumption that they're
ours. And we set the last_update_timestamp to -1 when we convert to
gossip_getchannels_entry to indicate no update.
This breaks the DEVELOPER=1 pruning test, since we hardcode the 1
week timeout. That's fixed in the next patch.

I initially disabled this until 0.16 because the withdraw command
was modified to require 'brct1' addresses for regtest.
But commit bd07a9 allows a regular testnet address to work
just as well. So renable this check.
FWIW, the tests without valgrind take 662 seconds before we reduced
the number of blocks, and only 648 seconds now.

This test generates a pre-bip173 testnet P2PKH address with bitcoin 0.15.1
which fails under the new verification checks for the bip173 network name.
This should be renabled with bitcoin 0.16 which can generate a bip173 address
for regtest with the bcrt prefix.
* Modifies invoice command to have the following format
invoice <msatoshi> <label> <desc> <?expiry> <?fallbackaddr>
* Adds support for Segwit bcrt1 addresses for withdraw
* Add test case for fallback address in invoice creation
* Create a common json_tok_address_scriptpubkey to be used
by invoice and withdraw commands.
We can do similar tricks to test other things, even to run without a
real bitcoind for faster testing, but for now we simply exit if a magic
file says so.

Due to a bug def_setfees(100, slow=100) would instead set immediate and

correct values, make the values truly optional as per documentation and
unit test this behavior.

Due to a bug pay(invoice, description='1000') resulted in payment of

Once we read a command, we are supposed to io_wait until it finishes.
However, we are actually woken in two places: when it's complete
(which is correct), and when it's written out (which is wrong).
We don't care when it's written out, only when it's finished:
refactor to make json_done() free and NULL the old ->current,
rather than have the callers do it. Now it's clear that it's
ready for both new output and new input.

Much like the database; peer contains id, address, channel contains
per-channel information. Where we create a channel, we always create
the peer too.
For the moment, peer->log and channel->log coexist side-by-side, to
reduce some of the churn.
Note that this changes the API to dev-forget-channel: if we have more
than one channel, we insist they specify the short-channel-id.

We get intermittant failure: WIRE_UNKNOWN_NEXT_PEER (First peer not ready)
because CHANNELD_NORMAL and actually telling gossipd that the channel
is available are distinct things: we need both.
(For test_closing_different_fees, we were testing CHANNELD_NORMAL on
the peer, not on l1, too).
But we may also directly send the announcement sigs if the height is
sufficient, so the simplest is to unify the messages.
