08e95d59b5 permute_tx: generic pointer map. 
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.

4a7418e3db channel: object to track channel state. 
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.

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.

this is the case, since the `channel_announcement` cannot be updated.

Moved the broadcast functionality to broadcast.[ch]. So far this
