fa32adf9dc25540ad27f5b82654c7057d7738627 scripted-diff: TxoutType C++11 scoped enum class (MarcoFalke)

fa41c657022b8f99c8e6718a0e33c5838c412a0b rpc: Simplify GetAllOutputTypes with the Join helper (MarcoFalke)

Pull request description:

  Non-scoped enums can accidentally and silently decay into an integral type. Also, the symbol names of the keys are exported to the surrounding (usually global) namespace.

  Fix both issues by switching to an `enum class TxoutType` in a (mostly) scripted-diff.
