f1ef7f0aa46338f4cd8de79696027a1bf868f359 Don't calculate tx fees for PSBTs with invalid money values (Andrew Chow)
Pull request description:
Fixes#17149
Two classes of issues were found by the psbt fuzzer: values out of range and causing overflows, and prevout indexes being out of range. This PR fixes both.
When accessing a specific output using the index given in the tx, check that it is actually a possible output before trying to access the output.
When summing and checking amounts for `decodepsbt` and `analyzepsbt`, make sure that the values are actually valid money values.. Otherwise, stop summing and don't show the fee. For `analyzepsbt`, return that the next role is the Creator since the Creator needs to remake the transaction to be valid.

eaf4f887348a08c620732125ad4430e1a133d434 Abstract out IsSegWitOutput from utxoupdatepsbt (Pieter Wuille)
Pull request description:
This adds a descriptors argument to the `utxoupdatepsbt` RPC. This means:
* Input and output scripts and keys will be filled in when known.
* P2SH-witness inputs will be filled in from the UTXO set when a descriptor is provided that shows they're spending segwit outputs.
This also moves some (newly) shared code to separate functions: `UpdatePSBTOutput` (an analogue to `SignPSBTInput`), `IsSegWitOutput`, and `EvalDescriptorStringOrObject` (implementing the string or object notation parsing used in `scantxoutset`).

fa9b60c842 Remove unused TransactionError constants (MarcoFalke)
Pull request description:
Fixup to #14978, which introduced a bunch of unused enum values, such as `UNKNOWN_ERROR`, `ERROR_COUNT` and `TRANSACTION_ERR_LAST`. None of those have a meaning in the context of an `enum class`, where the compiler can infer if all cases have been covered in a switch-case.
Also, move the global `::maxTxFee` back to the rpc caller, so it can be set on a per call basis (in the future).
