Changelog-Fixed: Detect a previously non-permanent error (`final_cltv_too_soon`) that has been merged into a permanent error (`incorrect_or_unknown_payment_details`), and retry that failure case in `pay`.
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.
This won't usually be visible to the end-user, since the pay plugin doesn't
do multi-part yet (and mpp requires EXPERIMENTAL_FEATURES), but we're ready
once it does.

The pay plugin has been supplying the bolt11 string since 0.7.0, so only
ancient "pay" commands would be omitted by this change.
You can create a no-bolt11 "sendpay" manually, but then you'll find it
in 'listsendpays'.
Changelog-Removed: JSON: `listpays` won't shown payments made via sendpay without a bolt11 string, or before 0.7.0.

Changelog-Added: RPC: The 'fundchannel' command now tries to connect to the peer before funding the channel, no need to 'connect' before 'fundchannel' anymore !
When doing the random walk through the channel, we now add the fees
(both the base and the proportional one) for that channel in addition to
the cltv delta.
Changelog-Added: Payment amount fuzzing is restored, but through shadow routing.
I was wondering why TAGS was missing some functions, and finally
tracked it down: PRINTF_FMT() confuses etags if it's at the start
of a function, and it ignores the rest of the file.
So we put PRINTF_FMT at the end, but that doesn't work for
*definitions*, only *declarations*. So we remove it from definitions
and add gratuitous declarations in the few static places.1

Currently the only source for amount_asset is the value getter on a tx output,
and we don't hand it too far around (mainly ignoring it if it isn't the
chain's main currency). Eventually we could bubble them up to the wallet, use
them to select outputs or actually support assets in the channels.
Since we don't hand them around too widely I thought it was ok for them to be
pass-by-value rather than having to allocate them and pass them around by
reference. They're just 41 bytes currently so the overhead should be ok.

The fundchannel plugin needs to know how to build a transaction, so we need to
tell it which chainparams to use. Also adds `chainparams` as a global, since
that seems to be the way to do things in plugins.
in order to preserve current behavior, we cap at max if specified 'all';
otherwise we fail since the amount requested is larger than the
channel max capacity
Previously, we'd fail on 'all'. `fundchannel_start` needs an amount
in order to start a funding transaction.
The way that we approach this is to first call `txprepare` with a
placeholder address and the 'all' amount; this will return the maximum
amount available. We then clamp this to the max_funding (currently
hardcoded, in the future we'd want to consult our/the peer's features) and
then use the amount on the output in the prepared transaction as the
funding amount. We then pass this amount to fundchannel_start,
after we've started it successfully we cancel the held placeholder
transaction and prepare a second transaction for the exact amount,
using the funding address that fundchannel_start passed back.
The string cut & paste hack was nasty; make ->failure a json_out
object so we can splice it in properly.

We now hand around struct json_out members, rather than using formatted
strings, so plugins need to construct them properly.
There's no automatic conversion between ' and " any more, so those
are eliminated too. pay still uses some manual construction of elements.
