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).

Also report tx and txid, and whether we closed unilaterally or
bilaterally, if we could close the channel.
Also make a manpage.

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.

We can have more than one; eg we might offer both bech32 and a p2sh
address, and in future we might offer v1 segwit, etc.

This allows us to have some default options that can then be overridden easily
on a per-test basis.

In the next commit we remove channels whose outpoint was spent from our network
view, so checking for it will not work anymore.

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:
