51a22c4274 doc: Fixed two small mistakes in the getroute documentation 
Two arguments were flipped and riskfactor was missing in the error
message returned from the JSON.

26d4042436 bugfix: Assert was killing daemon 
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.

8912272983 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.

fccab6411d 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.

1c4c874d3f 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.

e8e96e67d0 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!

c7e6f197b0 pytest: Chaning startup sentinel for bitcoind. 
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.

0fe53cc8e7 permute_tx: reintroduce permute map. 
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.
