D14890: Remove QSaveFile in favor of plain old file saving

[David Faure]

  Yeah that's the problem.
  
  The way I see it, the QIODevice API assumes that one will call errorString() only after some method returns an error, e.g. after QAbstractSocket::error() is emitted, or after socket.waitForEncrypted() returns false.
  
  QFile[Device] and QAbstractSocket add their own errorcode enums on top of that, but that's not part of the base QIODevice API, which is all we have in KCompressionDevice.
  
  Ideally QIODevice::close() would return a bool, and I'm more and more thinking that this should be done for Qt 6.
  But pending that, I'm afraid that we'll have to downcast to KCompressionDevice to call a new error() accessor after close()...
