The HSM will to need it to create signatures: we currently use it to create
privkeys then don't hand it around.

Really, we should have a 'struct point' since we don't use all points
as pubkeys. But this is the minimal fix to avoid type cast nastiness.

I went to the Nakamoto dinner last week and told some guys they
could get involved by improving our test coverage. So I updated
the docs for newbs like me. (I only recently discovered `PYTEST_PAR`).

Removed `json_get_params`.
Also added json_tok_percent and json_tok_newaddr. Probably should
have been a separate PR but it was so easy.

I saw an error in test_gossip_weirdalias in Travis, where listnodes(nodeid)
returned *BOTH* nodes; it happened to fail because [0] was the wrong one, but
it would have passed if the order had been different.
This helper asserts that we really do only have one element, and should
catch such bugs faster.

connect_control.c, dev_ping.c, gossip_control.c, invoice.c.
This converts about 50% of all calls of `json_get_params` to `param`.
After trying (and failing) to squash and rebase #1682 I just made a new branch
from a patch file and closed#1682.

I crashed the HSMD, and it gave no output at all. That's because we
were only reading the status fd when we were waiting for a reply.
Fix this by using a separate request fd and status fd, which also means
that hsm_sync_read() is no longer required.

We need this later, to generate its seed. When we switch to lnd's key system,
we'll only need this, and not peerid.
Note also that the peerid is not just for messages any more, too.

Often we only need a single secret, so it's clearer to have routines
to do just that. When we change to the lnd key scheme, there will be
no benefit in calculating them all together.
This also adds a test!

We use 'our_commit' for the commit we sign (ie. the remote commitment tx),
and vice versa. Use local/remote nomenclature.

Well, it's generated by shachain, so technically it is a sha256, but
that's an internal detail. It's a secret.

We already work around this by using an array with a 0/1 length convention,
but better to be explicit.

I could not figure out why test_announce_address suddenly stopped working:
I had previously been using DEVELOPER=1 on the cmdline for historical
reasons when testing locally.

- fixes problem with polling interval > 150 * 0.9
- fixes log message 'feerate hit floor' at every feerate change
- smoothed fee now reaches 90% of (exp weighted) fee estimates polled in last
120s, independent of polling interval
- only apply smoothing when effect > 10 percent so it doesn't correct forever
- fix indentation
This is a cosmetic change only. No functional changes.
I shortened the names of macros and changed param_parse() to param().
Also went through params.h with a fine-toothed comb and updated the comments
to reflect the current API.
I wanted to change the files:
params.c -> param.c
params.h -> param.h
run-params.c -> run->param.c
but that confused `git diff` for params.h so its best left for another PR.
I'm keeping #1682 updated locally with all these changes.

@wythe points out that many cases want a default value, not NULL.
Nicer to do it in the param_parse() call.

I'm not completely convinced that it's only ever set to a failcode
with the BADONION bit set, especially after the previous patches in
this series. Now that channeld can handle arbitrary failcodes passed
this way, simply rename it.
We add marshalling assertions that only one of failcode and failreason
is set, and we unmarshal an empty 'fail' to NULL (just the the
generated unmarshalling code does).

None of these sanity checks should fail, but let's be thorough: we
were testing for htlc->fail but not failcode when fulfilling an HTLC.
The failing-htlc case had this correct already.

'struct htlc' in channeld has a 'malformed' field, which is really only
used in the "retransmit updates on reconnect" case. That's quite confusing,
and I'm not entirely convinced that it can only be set to a failcode
with the BADONION bit set.
So generalize it, using the same logic we use in the master daemon:
failcode: a locally generated error, for channeld to turn into the appropriate
error message.
fail: a remotely generated onion error, for forwarding.
Either of these being non-zero/non-NULL means we've failed, and only one
should be set at any time.
We unify the "send htlc fail/fulfill update due to retransmit" and the
normal send update paths, by always calling send_fail_or_fulfill.
This unification revealed that we accidentally skipped the
onion-wrapping stage when we retransmit failed htlcs!
