This makes it easier to handle descriptor strings manually. E.g. an RPC call that takes an array of descriptors can now use '["desc": ".../0h/..."]'.
Both markers can still be parsed. The default for new descriptors is changed to h. In normalized form h is also used. For private keys the chosen marker is preserved in a round trip.
The hdkeypath field in getaddressinfo is also impacted by this change.
We were throwing two different errors for the same problematic:
* "Expected type {expected], got {type}" --> RPCTypeCheckArgument()
* "JSON value of type {type} is not of expected type {expected}" --> UniValue::checkType()
- Get rid of hardcoded wallet "" names and -wallet="" args
- Get rid of setup_nodes (-wallet, -nowallet, -disablewallet) argument rewriting
Motivation:
- Simplify test framework behavior so it's easier to write new tests without
having arguments mangled by the framework
- Make tests more readable, replacing unexplained "" string literals with
default_wallet_name references
- Make it trivial to update default wallet name and wallet data filename for
sqlite #19077 testing
- Stop relying on -wallet arguments to create wallets, so it is easy to change
-wallet option in the future to only load existing wallets not create new
ones (to avoid accidental wallet creation, and encourage use of wallet
encryption and descriptor features)
