It's in the shachain, so storing it is completely redundant. We leave
it in for the moment so we can assert() that nothing has changed.

When loading from DB the list of htlcs was not being initialized which
caused a segfault when the first commit came around, this fixes it.

The peer->seed needs to be unique for each channel, since bitcoin
pubkeys and the shachain are generated from it. However we also need
to guarantee that the same seed is generated for a given channel every
time, e.g., upon a restart. The DB channel ID is guaranteed to be
unique, and will not change throughout the lifetime of a channel, so
we simply mix it in, instead of a separate increasing counter.
We also needed to make sure to store in the DB before deriving the
seed, in order to get an ID assigned by the DB.

This is the big one, and it's completely anticlimactic: it loads all
channels that have reached opening and are not marked as
closingd_complete into memory, that's it.

They happen to advance at the same pace but mixing them may have
unforeseen consequences, and I have done so a few times already so
this explicitly separates them.

This was supposed to be a temporary solution anyway, and I had a
rather annoying mixup between peer_id and unique_id, the latter of
which is actually a connection identifier.
Add the channel to the peer on the two open paths (fundee and funder)
and store it into the database. Currently fails when opening a channel
to a known peer after loading from DB because we attempt to insert a
new peer with the same node_id. Will fix later.
I was hoping to trigger on more things from the bitcoind process, but
stuff like mempool is hard to trigger on. Reducing to info so we can
work a bit easier with pdb and the log becomes less noisy.
If we kill the daemon without performing any commits we ended up with
a 0 instead of UINT48_MAX which was expected.

This is required for onchaind: we want to watch all descendents by default,
as to do otherwise would be racy, which means we need to traverse the outputs
when a tx appears.

And store in peer->last_tx/peer->last_sig like all other places,
that way we broadcast it if we need to.
Note: the removal of tmpctx in funder_channel() is needed because we
use txs[0], which was allocated off tmpctx.

The signing code asserts these are NULL, and if we unmarshal from the
wire then sign them, it gets upset.

We'll need this for testing nodes going down during payment.
However, there's no good way to silence the threads that I can tell,
so we get a nasty backtrace from it.

We need to check if we exit after sending a revoke_and_ack, otherwise
channeld ends up getting the closing_signed packet.
