gossip: Prevent normal messages to trigger the staggered broadcast
...
Only call `peer_dump_gossip` if the broadcast timer actually
expired. previously it could get triggered by any normal message.

gossip: Add timer and normal queue for messages
...
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.

refactor: Making timers independent of the lightningd_state

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.

commit_tx: make interface side-agnostic.
...
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 used to have a permutation map; this reintroduces a variant which

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.
