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.

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).

It's only used for tests, but it's better to use the wallet_channels_load_active like
the real code.

We stopped too early; we should continue and make sure it all goes well.
This means we have to fix them to be deterministic: by generating 2
blocks at once in test_htlc_in_timeout, we raced between fulfill and
timeout on the HTLC. Now it's always fulfilled.
Also, fixed confusing comments: l1 doesn't drop to chain.

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.

OUR_HTLC_TIMEOUT_TO_US = normal tx, used to timeout htlc in their commit tx.
OUR_HTLC_TIMEOUT_TX = dual-sig tx with delay, used to timeout htlc in our commit tx.
Only one test looks at that string, so fix that too.

Sometimes we could get into a situation in which we knew the channel
but couldn't find it via the short_channel_id. That'd result in a
replacement which triggered an assert.

The test_reconnect_normal test is failing rather consistently on 32bit
architectures, disabling to reduce noise. Issue #468 tracks progress.

With python-bitcoinlib==0.9.0 it appears that the URL based auth
information is no longer used, so we fall back to reading the config
file for the bitcoind daemon instead.

The use of status_failed() requires a stubs update, which fails
with unnamed parameters, so tweak the status.h header as well.

If we side-load a channel, using local-add or the removed JSON-RPC
call, then we could end up in a situation in which a channel is
present, but has no associated channel_announcement. The presence of
the channel_announcement was used to identify new channels, so this
could lead to channels always being considered new. This then caused
the announcements being added to the queue always, resulting in
channel_updates preceeding the announcement.
