client: Initial RequestInput handling support
When receiving a RequestInput Agent API D-Bus call, ask the input in a somewhat logical order from the user with user names first and passwords next. If a passphrase is entered, ignore any WPS pin code requests. Prepare for passphrase length checking by going through the RequestInput message to get the 'Type' argument.
