In this commit, we add the coin selection strategy option to the following
on-chain RPCs `fundpsbt`, `batchopenchannel`, `estimatefee`, `sendcoins`,
`sendmany`, and `sendoutputs`.
In some situations (for example in Taproot Assets), we need to be able
to prove that an address is a bare BIP-0086 address that doesn't commit
to any script. We can do that by providing the BIP-0032 derivation info
and internal key.
This is a helper function that we will need to accurately determine the
weight of inputs specified in a PSBT.
Due to the nature of P2WSH and script-spend P2TR inputs, we can only
accurately estimate their weights if the full witness is already known.
So this helper function rejects inputs that use a script spend path but
don't fully specify the complete witness stack.
In theory, it should be only one custom account with a given name. However,
users could have created custom accounts with various key scopes. In that case,
'LookupAccount' has a non deterministic behaviour. To fix that, we browse
through all key scopes (deterministically) and return the first account we found.
By default, P2TR addresses are used for changes. However, some users
might encounter some problems with this change. We add the possibility
to define a custom address type in FundPsbt for default/imported accounts
(only P2TR for now). If no address type is specified for these accounts,
we will use P2WKH by default.
Fixes#6626.
If either of the two fields FinalScriptSig or FinalScriptWitness is set
on an input of a PSBT then that results in most of the fields of that
input not to be serialized in the packet anymore, since the input is
considered to be complete.
But because a signer isn't supposed to set any of the Final* fields,
this was wrong from the beginning. Only the finalizer will set those
fields.
