Similar to the previous "handle peer input before gossip input", this
fixes similar potential deadlock for closingd and openingd which use
peer_or_gossip_sync_read.

This solves (or at least reduces probability of) a deadlock in channeld
when there is lot of gossip traffic, see issue #2286. That issue is
almost identical to #1943 (deadlock in openingd) and so is the fix.
- result fundchannel command now depends on successful or failed broadcast of the funding tx
- failure returns error code FUNDING_BROADCAST_FAIL
- don't fail the channel when broadcast failed, but keep in CHANNELD_AWAITING_LOCKIN
- after fixing the initial broadcast failure, the user could manually rebroadcast the tx and
keep the channel
openingd/opening_funder_finished:
- broadcast_tx callback function now handles both success and failure
jsonrpc: added error code FUNDING_BROADCAST_FAIL
manpage: added error code returned by fundchannel command
This makes the user more aware of broadcast failure, so it hopefully doesn't
try to broadcast new tx's that depend on its change_outputs. Some users have reported (see
issue #2171) a whole sequence of fundings failing, because each funding was using the change
output of the previous one, which would not confirm.
We actually produce an invalid JSON error at the moment: bitcoin-cli
complains "JSON value is not an integer as expected" rather than returning
the given error. Make our error a valid JSON RPC error.

We were restarting the with the nodes before, which was causing some
port contention. This is more natural since `bitcoind` will take care
of terminating all proxies it returned.

The use of `json_tok_full_len` and `json_tok_full` in addition to
single quotes will result in double quoting, which is really weird. I
opted to single quoting using `'` instead which does not need to be
escaped.

List the final one instead; if there's an error from the node it
may actually make sense to blame that channel (ie. previous node
did something wrong).

We no longer need a 'sendpay_result' structure, we can pass
appropriate parameter directly now they're simple calls.
Every waitsendpay command ends in tell_waiters_failed or
tell_waiters_success, which call sendpay_success or sendpay_fail on
all matching waiters. These all return 'struct command_result *'.
In cases where the result is immediately known, we call
sendpay_success/sendpay_fail directly for the command.
This also adds a helpful 'failcodename' field to the JSON output.
[ This was four separate cleanup patches, but that contained much
redundancy and was even worse to review ]

With only one caller, we don't need a callback pointer any more; we can simply
call the function.
This required some code shuffling, and I changed the callback function
arguments to be in a more natural order, now they're not used as
callbacks.

Now we don't have a second caller for these routines, we can move
them back into pay.c and make the functions static.

As a general rule, lightningd shouldn't parse user packets. We move the
parsing into gossipd, and have it respond only to permanent failures.
Note that we should *not* unconditionally remove a channel on
WIRE_INVALID_ONION_HMAC, as this can be triggered (and we do!) by
feeding sendpay a route with an incorrect pubkey.

We had a bug 0ba547ee10 caused by
short_channel_id overflow. If we'd caught this, we'd have terminated
the peer instead of crashing, so add appropriate checks.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
I upgraded my node with --disable-compat, and a heap of channels closed like:
CHANNELD_NORMAL:We disagree on short_channel_ids: I have 557653x0x1351, you say 557653x2373x1",
This is because the scids are strings in the databases, and it failed to parse
them properly.
Now we'll not start if that happens.

Internally libplugin turns ' into ", which causes these messages to produce
bad JSON.
The real fix is to remove the '->" convenience substitution and port the
JSON creation APIs into common/ from lightningd/

Spurious errors were occuring around checking the provided
current commitment point from the peer on reconnect when
option_data_loss_protect is enabled. The problem was that
we were using an inaccurate measure to screen for which
commitment point to compare the peer's provided one to.
This fixes the problem with screening, plus makes our
data_loss test a teensy bit more robust.
Valgrind seems to be slowing the pay-plugin down enough for the 10
seconds timeout to get triggered on a semi-regular basis.

Christian points out that we can iterate by ->size rather than calling
json_next() to find the end (which traverses the entire object!).
Now ->size is reliable (since previous patch), this is OK.

jsmn would accept invalid JSON objects. This is bad because it would
set ->size incorrectly: we expect to have at least size * 2 tokens (in
pairs). We want to rely on ->size, but this would create an exploitable
buffer overflow!
Fortunately, this is fixed upstream, so we add a test and upgrade to v1.0.0.

Wasn't using valid JSON, but worked anyway. This is actually OK
because we don't rely on tok->size, but we want to, so another fix
coming.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
The external/jsmn/README.md only says:
int size; // Number of child (nested) tokens
But it only counts *direct* children, or *direct* members for an object.
This test verifies this (the bug proved to be elsewhere: see next patch!).

Had a couple of tests randomly fail because a valgrind error file was
not empty. It contained:

that (useless) error.

So add a new 'strategy' field. This makes it clearer what is going
on, currently one of:
* "Initial attempt"
* "Excluded channel <scid>"
* "Removed route hint"
* "Excluded expensive channel <scid>"
* "Excluded delaying channel <scid>"
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We sanitize the routes: firstly, we assume appending so eliminate the
first hop if the route points straight to us. Secondly, eliminate empty
hints. Thirdly, trim overlong hints.
Then we just use the first route hint.
