niftynei 303263d381 psbt: clean up interface for setting metadata on PSBT inputs
it's just neater if it's not all wrapped up together, simplifies the
interface a smidge

niftynei 169b7817dc psbt: only compare a subset of psbt input/output fields
At some point, it's ok to add more extra info to a psbt and still not
have that be counted as 'diff'd.

FIXME: requires wallycore

niftynei 8d429ecd06 df: add needed info to any PSBT we produce
dual funding needs the max-witness-len and utxo fields set for every
input. we should add them when we create a 'fundpsbt', so that every
psbt that c-lightning generates is dual-funding ready

niftynei 42a38b9808 channel_id: add v2 channel_id derivtion helper
v2 of channel open uses the channel revocation basepoints to calculate
the channel_id, instead of the funding_txid + outnum

Moving away from the funding_txid opens the way for splicing + rbf

niftynei 864f2f3e21 channel_id: save to database, dont derive from funding_txid
v2 channel open uses a different method to derive the channel_id, so now
we save it to the database so that we dont have to remember how to
derive it for each.

includes a migration for existing channels

niftynei 437ca83fa5 elementsd: add a fee output to a fund/utxopsbt for elements transactions
fundpsbt / utxopsbt create a (typically) output-less PSBT,
however for elements we require the fees to be encapsulated in an
output.

this patch updates fundpsbt / utxopsbt to add a fee output for elements
transactions. includes test updates.

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
specified "wumbo" twice.  We should really just use the proper name

ZmnSCPxj jxPCSnmZ 6c13e9b300 bitcoin/script.c: Add scriptpubkey_opreturn_padded, which creates an OP_RETURN with a pointless random 20-byte padding.
In the case of `donateutxo`, this is needed since a simple spend of a P2WPKH to an `OP_RETURN` would be below the minimum transaction size.
Sizes below 20 are not plausible as commitments.

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.

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 62f80f74ec pytest: fix flake in test_mpp_interference_2
I screwed up the rotation logic in an earlier varient of this PR, and
it lead me to discover why test_mpp_interference_2 was flaky.

Really, we should keep a fuzzy estimator of how much payment is
outstanding, but in practice rotation is probably good enough.

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