Merge #14162: gui: Also log and print messages or questions like bitcoind

fa7e9694e1ed5406036620d4bf0b72a2aa984578 qt: Also log and print messages or questions like bitcoind (MarcoFalke)
dd031e383975ae42b4cddd9a5bf6080ef5b46afa noui: Move handlers to header file (MarcoFalke)

Pull request description:

  Testing and debugging after shutdown are harder if the node was run through the gui, because errors and warnings would not be logged to the debug.log or written to the stderr (as is the case for bitcoind).
