Christian Decker ef7a63d8f8 elements: Move from a global is_elements to a global chainparams
We now have a pointer to chainparams, that fails valgrind if we do anything
chain-specific before setting it.

Rusty Russell 147eaced2e developer: consolidiate gossip timing options into one --dev-fast-gossip.
It's generally clearer to have simple hardcoded numbers with an
#if DEVELOPER around it, than apparent variables which aren't, really.

Interestingly, our pruning test was always kinda broken: we have to pass
two cycles, since l2 will refresh the channel once to avoid pruning.

Do the more obvious thing, and cut the network in half and check that
l1 and l3 time out.

Rusty Russell ca28c30eff funding: don't allow funding new channels until we're synced.
This is probably worth preventing.

1. Our depth estimate would be inaccurate possibly leading to us
   timing out too early.
2. If we're not up-to-date our onchain funds are unknown.
3. We wouldn't be able to send or receive HTLCs until we're synced anyway.

Christian Decker 5dff67900e tx: Add chainparams when deserializing transactions from wire msgs
This is the other origin, besides `bitcoin_tx`, where we create `bitcoin_tx`
instances, so add the context as soon as possible. Sadly I can't weave the
chainparams into the deserialization code since that'd need to change all the
generated wire code as well.

lisa neigut 4638995037 tests: log funder_faileds as unusual not broken
test_funding_cancel_race explicitly attempts to trigger this via a race
condition; this conflicts with our post-test checks that no broken
logs were logged. as a middle ground, we log it as unusual, not broken,
as it's possible for it to attempt to fail if it was begun at the same
time as the complete is.

Rusty Russell 9fdcb1a122 openingd: remove unnecessary is_err flag.
It probably doesn't matter to "fundchannel_cancel" exactly why the

Rusty Russell 4c118bcdba openingd: fix compile error caused by merge.
Compile broke because we were using low-level JSON primitives here
(which, incidentally, would produce bad JSON now, since we can't just
put a raw string inside an object!).

Use json_add_string, which also has the benefit of escaping JSON
for us.

lisa neigut 478762dbd2 funding: wire up funding_continue
Big wiring re-org for funding-continue

In openingd, we move the 'persistent' state (their basepoints,
pubkey, and the minimum_depth requirement for the opening tx) into
the state object. We also look to keep code-reuse between
'continue' and normal 'fundchannel' as high as possible. Both
of these call the same 'fundchannel_reply' at the end.

In opening_control.c, we remap fundchannel_reply such that it is
now aware of the difference between an external/internally funded
channel open. It's the same return path, with the difference that
one finishes making and broadcasting the funding transaction; the
other is skips this.

Rusty Russell bb7bbd03c5 lightningd: have json_stream_success start the "result" object.
"result" should always be an object (so that we can add new fields),
so make that implicit in json_stream_success.

This makes our primitives well-formed: we previously used NULL as our
fieldname when calling the first json_object_start, which is a hack
since we're actually in an object and the fieldname is 'result' (which
was already written by json_object_start).

There were only two cases which didn't do this:
1. dev-memdump returned an array.  No API guarantees on this.
2. shutdown returned a string.

I temporarily made shutdown return an empty object, which shouldn't
break anything, but I want to fix that later anyway.

We currently allocate utxos off cmd, but the next commit will persist a
wtx beyond the command which created it, breaking that assumption.

In general, a struct member should be owned by the struct itself, and
a tal context should be an explicit arg, not implicit.
