Finally, extends the 'close_to' functionality up to the flagship 'open a
channel' command.
Changelog-Added: JSON-API `fundchannel` now accepts an optional 'close_to' param, a bitcoin address that the channel funding should be sent to on close. Requires `opt_upfront_shutdownscript`
This should be more robust in future: we SHA256 all of the deps.
For wiregen we prefix with EXPERIMENTAL_FEATURES, since it can effect them.

It's currently always 0, but it won't be once we replace txprepare.

Changelog-Added: JSON-RPC: `fundchannel` has new `outnum` field indicating which output of the transaction funds the channel.
ChangeLog-Fixed: Clarified about connection in documentation. Also, `fundchannel` already `connect`s if your node knows how to contact the desired peer for a few versions now, so clarify documentation about this as well.
it's that time of year (merry xmas!)
enables the ability to push_msat on fundchannel
Changelog-Added: RPC: `fundchannel` and `fundchannel_start` can now accept an optional parameter, `push_msat`, which will gift that amount of satoshis to the peer at channel open.
mrkd started enforcing the `name -- short description` style of top-level
headings somewhere, and was thus failing to build the man-pages. I swapped
the title and with the existing short description to make it work
again. `mrkd` will automatically infer the section from the filename so no
need to put it in the title as well.
In addition I removed the "last updated" lines at the bottom since they are
out of date at best, and misleading at the worst. If we want to keep them, I'd
suggest generating them from the commit that last touched them.
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.

I tried to fundchannel 0.01btc, and of course it wanted 8 decimals exactly.
If I can't get this right, it's probably a bad idea.
I still don't allow whole number of btc though, since that's probably a mistake
and you're not supposed to put that much in c-lightning yet :)

- 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.
And, reluctantly, default to bitcoind style.

The easiest way to do this is to play with the 'wallet_tx' semantics
and have 'amount' have meaning even when 'all_funds' is set.
Note that we change the string 'Cannot afford funding transaction' to
'Cannot afford transaction' as this code is also used for withdrawls.
