This seems rather easy to fix, the only case we do not want to set
`STATE_SHUTDOWN` us when we have updates which we have not committed
yet, which is handled separately in the other IF-branch.
The peer is woken up every 30 seconds to deliver the backlog of
messages. Additionally I added the normal message queue to be able to
send non-gossip message to the peer.
The `dstate` reference was only an indirection to the `timers`
sub-structure anyway, so removing this indirection allows us to reuse
the timers in the subdaemon arch.
Turns out we want to permute transactions for the wallet too, so we
use void ** rather than assume we're shuffling htlc ** (and do inputs,
too!).

This is a workaround; eventually libwally will be a nice shared library that
we won't have to bundle, and clashing with internal symbols won't be
a problem.

This object is basically the embodyment of BOLT #2. Each HTLC already
knows its own state; this moves them between states and keeps them
consistent.

It's currently written to produce "local" commit-txs, but of course we
need to produce remote ones too, for signing.
Thus instead of using "remote" and "local" we use "other" and "self",
and indicate with a single "side" flag which we're generating (because
that changes how HTLCs are interpreted).
This also adds to the tests: generate the remote view of the commit_tx
and make sure it matches!

We were using the remote per_commitment_point instead of the local
per_commitment_point to generate the remotekey for the local transaction.

It's awkward to handle them differently. But this change means we
need to expose them to the generated code.

By looking for 'Done loading' in the log output we should actually be
called after `SetRPCWarmupFinished` in bitcoind. Only then is it safe
to make RPC calls. This resulted in the test suite being a bit flaky.
We used to have a permutation map; this reintroduces a variant which
uses the htlc pointers directly.
We need this because we have to send the htlc-tx signatures in output
order as part of the protocol: without two-stage HTLCs we only needed
to wire them up in the unilateral spend case so we simply brute-forced
the ordering.

This is a step away from the previous more generic script types into
specific helpers for each transaction type we need.
