Also one less headache for reproducible builds. But unlike
libsodium, this only seems common in Ubuntu.

It was waiting for a remote channel, but not for all the interesting
channels we want to check. It can sometimes happen that further away
channels are added before closer ones are added, depending on
propagation path, flush timers and bitcoind poll timers. This now just
checks for all channels, which also reduces the ambiguity of whether
we selected a path solely because we were lacking alternatives.

The next patch wants to decorate the methods with a compulsory
'usage' option, which doesn't make sense for init. So I wanted
to change the init to its own decoration.

We store it in a strmap. This means we call the jsonrpc handler earlier,
so all callers need to call param() before they do anything else; only
json_listaddrs and json_help needed fixing.
Plugins still use '[usage]' for now.

Next patch will call commands to get usage inside jsonrpc_new(): to do
this it will need access to ld->jsonrpc, so we can't use the current
pattern.

This fixes a bug with a plugin duplicating an existing name
where we'd crash, too.
This doesn't work for builtins, which aren't tal objects, so

This was failing the docker hub builds, since the git-config retains
an absolute path to the worktree location when cloning. Copying it
over from the host system means that this path now points to a
non-existent location, which then interfered with the submodule
initialization.
This fixes it by not using the copy directly, but rather it creates a
clean clone from the copied location, including a submodule init.

Travis timed out.
Waiting for three fundchannel commands depends on the bitcoind polling
interval (30 seconds), and then waiting for gossip propagation
requires two propagation intervals (120 seconds).

Up until now, riskfactor was useless due to implementation bugs, and
also the default setting is wrong (too low to have an effect on
reasonable payment scenarios).
Let's simplify the definition (by assuming that P(failure) of a node
is 1), to make it a simple percentage. I examined the current network
fees to see what would work, and under this definition, a default of
10 seems reasonable (equivalent to 1000 under the old definition).
It is *this* change which finally fixes our test case! The riskfactor
is now 40msat (1500000 * 14 * 10 / 5259600 = 39.9), comparable with
worst-case fuzz is 50msat (1001 * 0.05 = 50).

We were only comparing by total msatoshis.
Note, this *still* isn't sufficient to fix our indirect problem, as
our risk values are all 1 (the minimum):
lightning_gossipd(25480): 2 hop solution: 1501990 + 2
lightning_gossipd(25480): 3 hop solution: 1501971 + 3
...
lightning_gossipd(25480): => chose 3 hop solution

We used a u16, and a 1000 multiplier, which meant we wrapped at
riskfactor 66. We also never undid the multiplier, so we ended up
applying 1000x the riskfactor they specified.
This changes us to pass the riskfactor with a 1M multiplier. The next
patch changes the definition of riskfactor to be more useful.

The test sometimes passes: our routing logic always chooses between
the shorter of two equal-cost routes (because we compare best with <
not <=).
By adding another hop, we add more noise, and by making the alternate
route fee 0 we provide the worst case.
But to be fair, we make the amount of the payment ~50c (15,000,000
msat), and increase our cltv-delay to 14 and fee-base 1000 to match
mainnet. The final patch shows the effect of this choice.
Otherwise our risk penalty is completely in the noise on
mainnet which has the vast majority of fees set at 1000msat + 1ppm.

This is the direct cause of the failure of the original
test_pay_direct test and it makes sense: invoice routehints may not be
necessary, so try without them *first* rather than last.
We didn't mention the use of routehints in CHANGELOG at all yet, so
do that now.

We have a seed, which is for (future!) unit testing consistency. This
makes it change every time, so our pay_direct_test is more useful.
I tried restarting the noed around the loop, but it tended to fail
rebinding to the same port for some reason?

Add the change output to owned_txfilter so its entry in db will
get a confirmation_height when detected in a block by filter_block_txs
before this commit, after a 'withdraw' command, 'listfunds' would
not show our change outputs as confirmed
Modified the log message in wallet_extract_owned_outputs to
append 'CONFIRMED' when it is called with a blockheight arg.
To make distinction between (1st call) when adding owned output to the
db and (2th call) when confirmed in block.
Otherwise a straight "make install" gives:
install: cannot stat 'plugins/pay': No such file or directory

Similar to the previous "handle peer input before gossip input", this

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.
