Also report tx and txid, and whether we closed unilaterally or
bilaterally, if we could close the channel.
Also make a manpage.
Fixes: #1207Fixes: #714Fixes: #622
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.

For older clients we could do more exhaustive checks, but effort is better
spent on removing this altogether post 0.6 as clients upgrade.

@ZmnSCPxj points out that this is allowed, though invalid:
1. commitment_fee = 1000
2. funder: 800
3. fundee: 200
4. funder: 900
We need to adjust the feerange using the initial funder offer.
We had an intermittant test failure, where the fee we negotiated was
further from our ideal than the final commitment transaction. It worked
fine if the other side sent the mutual close first, but not if we sent
our unilateral close first.

Really, if we're prepared to negotiate it, we should be prepared to
accept it ourselves. Simply take the cheapest tx which is above our
minimum.

The only use for these was to compute their txids so we could notify depth
in case of reorgs.

We are slowly hollowing out the in-memory blockchain representation to make
restarts easier.

All of the callback functions were only using the tx to generate the txid again,
so we just pass that in directly and save passing the tx itself.
This is a simplification to move to the DB backed depth callbacks. It'd be
rather wasteful to read the rawtx and deserialize just to serialize right away
again to find the txid, when we already searched the DB for exactly that txid.

This will later allow us to determine the transaction confirmation count, and
recover transactions for rebroadcasts.

Currently these are either transactions we sent ourselves or transactions that
we are watching because they are part of a channel.

Christian points out that we don't get spend notifications for old
channels if we truncate the store. We'd need more work to do this,
either validating the channels are still unspent, or replaying old
blocks from the truncation point.

Since we open with O_APPEND, any write() will append as we want it to.
But we want to distinguish a new store creation from a truncation due
to bad version.

If something goes (fatally) wrong, we won't add it to the store.
This reveals a latent bug in routing_add_channel_announcement() and
friend which did a take() on msg, which it doesn't own. TAKES means
that it will take ownership IF the caller requests, not an unconditional
ownership transfer (which is an antipattern).

We enter nodes in the map when we create channels, but those channels
could be local and unannounced. This triggered a failure in
test_gossip_persistence since the store truncated when it saw the
first thing was a node_announce.

Internally both payment and routing use 64-bit, but the interface
between them used 32-bit.
Since both components already support 64-bit we should use that.
In the short_channel_id check we were copying the entire result into the next
bitcoin-cli call, including the newline character.

Repeated crashes could result in the `last_processed_block` variable being
pushed further and further into the past (in some cases going as far back as
scanning blocks from 2012...). This is a stop-gap solution that just lower
bounds the value to what is the first possible block we might be interested in
LN, until we have the 0-rescan fix I'm working on.
