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.

We should never be evicting channel_announcements because a) they were
deeply buried and should not change the short_channel_id/tag, b) they
are static.

Adds two new environment variables TEST_GROUP_COUNT and TEST_GROUP to
split the integration tests into groups and run only a selected group.
This allows us to increase the TEST_GROUP_COUNT and add a new
TEST_GROUP to avoid bumping up against the time limit when running in
valgrind.

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.
