Fixing the following error by changing 'enum feerate' to int.

niftynei c50f377a85 psbt: pull out changeset logic into common, update API
Greatly simplify the changeset API. Instead of 'diff' we simply generate
the changes.

Also pulls up the 'next message' method, as at some point the
interactive tx protocol will be used for other things as well
(splices/closes etc)

Rusty Russell 91caf4cc30 options: handle wumbo and large-channels aliases properly.
Too trivial a fix to really list in Changelog, but I noticed that we

ZmnSCPxj jxPCSnmZ ee276bcb86 plugins/bcli.c: `sendrawtransaction` now has a required `allowhighfees` argument.
Changelog-Deprecated: plugin: `bcli` replacements should note that `sendrawtransaction` now has a second required Boolean argument, `allowhighfees`, which if `true`, means ignore any fee limits and just broadcast the transaction. Use `--deprecated-apis` to use older `bcli` replacement plugins that only support a single argument.

Christian Decker cab52f1197 topology: Notify gossipd about spends after processing the block
We defer the notification to gossipd till the end of the spends. By itself not
a huge change, but it allows us to later migrate to doing updates blindly and
using the DB as our ground truth. It also allows us to simplify the
`wallet_outpoint_spend` semantics to not return two values in the next commit.

Rusty Russell 2be1f3fe1b lightningd: extract routehint selection code.
We're going to want this for bolt13 formation as well.

As a result of reworking the logic into "candidate selection" then
"route hint selection", we need to change the way round-robin works.

Rusty Russell 83298c030a wallet: switch over to withdraw in module, remove lots of unused code.
This removes the reservation cleanup at startup, too, now they're all
using 'reserved_til'.

This changes test_withdraw, since it asserted that outputs were marked
spent as soon as we broadcast a transaction: now they're reserved until
it's mined.  Similarly, test_addfunds_from_block assumed we'd see funds
as soon as we broadcast the tx.

Michael Schmoock a3e18a6aba openchannel: make openchannel hook chainable
This will make the `openchannel_hook` chainable. Logic is as follows:

 - If more than one plugin uses the `close_to` parameter, take the first
   value and log_unusual for the others.

Christian Decker d7ff74e8f6 json: Only start parsing once we're sure we have a message
PR #3957 improved performance considerably, however we still look over the
entire message for the message separator. If instead we just look in the
incrementally read data, we remove the quadratic behavior for large messages.

This is safe since we then loop over the messages which would drain any
message separator from the buffer before we attempt the next read.

Rusty Russell 9b8f08a8a0 lightningd: return min-capacity-sat to its intended purpose.
And document exactly what it does: insist that an HTLC can pass of
this value (module assumptions of feerate).

Note that we remove the "is_opener" test from the capacity calculation
for anchor fees: it doesn't matter which side it is, someone has to pay
for anchor fees to it deducts from capacity.

This change breaks the test, which we rewrite.

Rusty Russell 3ed03f9c8f common: make json_parse_input API retry friendly.
The jsmn parser is a beautiful piece of code.  In particular, you can parse
part of a string, then continue where you left off.

We don't take advantage of this, however, meaning for large JSON objects
we parse them multiple times before finally having enough to complete.

Expose the parser state and tokens through the API, so the caller can pass
them in repeatedly.  For the moment, every caller is allocates each time
(except the unit tests).
