Merge #18244: rpc: fundrawtransaction and walletcreatefundedpsbt also lock manually selected coins 
6d1f51343cf11b07cd401fbd0c5bc3603e185a0e [rpc] fundrawtransaction, walletcreatefundedpsbt lock manually selected coins (Sjors Provoost)

Pull request description:

  When using `fundrawtransaction` and `walletcreatefundedpsbt` with `lockUnspents`, it would only lock automatically selected coins, not manually selected coins. That doesn't make much sense to me if the goal is to prevent accidentally double-spending yourself before you broadcast a transaction.

  Note that when  creating a transaction, manually selected coins are automatic "unlocked" (or more accurately: the lock is ignored). Earlier versions of this PR introduced an error when a locked coin is manually selected, but this idea was abandoned after some discussion. An application that uses this RPC should either rely on automatic coin selection (with `lockUnspents`) or handle lock concurrency itself with manual coin selection. In particular it needs to make sure to avoid/pause calls with automatic coin selection between calling `lockunspent` and the subsequent spending RPC.

  See #7518 for historical background.

Updated RPCs

  • fundrawtransaction and walletcreatefundedpsbt when used with the lockUnspents argument now lock manually selected coins, in addition to automatically selected coins. Note that locked coins are never used in automatic coin selection, but can still be manually selected.
