Needs rebase but ACK 3693771b
Nice that we don't longer need to produce so many dummy signatures. Should get us a pretty decent speedup in AvailableCoins for big wallets.
…DestinationForScript It's already checked by its (only) caller, AddAndGetMultisigDestination.

It was used back when we didn't have a concept of descriptor. Now we can check for solvability using descriptors.

b16f93c script/sign: remove needless IsSolvable() utility (Antoine Poinsot) c232ef2 outputtype: remove redundant check for uncompressed keys in AddAndGetDestinationForScript (Antoine Poinsot) Pull request description: Now that we have descriptors there is no need to try to sign for a scriptPubKey using dummy signatures, and using a mocked verification of this witness against the interpreter, just to make sure we know how to spend such a Script. Just try to infer a solvable descriptor: any scriptPubKey that we can sign for can be inferred as such. This came up in bitcoin#24149 but i think it's worth it on its own. ACKs for top commit: instagibbs: ACK bitcoin@b16f93c achow101: re-ACK b16f93c furszy: ACK b16f93c, only change is the `IsSolvable` helper function removal.

Now that we have descriptors there is no need to try to sign for a scriptPubKey using dummy signatures, and using a mocked verification of this witness against the interpreter, just to make sure we know how to spend such a Script. Just try to infer a solvable descriptor: any scriptPubKey that we can sign for can be inferred as such.
