Improve support for keyboard, mouse and usb-controller

- add support to choose preferred usb-controller either ehci (USB2.0) or xhci (USB 3.0)
- add support to choose preferred keyboard either ps2, usb or virtio
- add support to choose preferred keyboard-layout
- add support to choose preferred mouse either ps2, usb, tablet, virtio
- fix some bugs regarding missing variables - releated to MONTITOR_TELNET_* and SERIAL_TELNET_*
- Support implemented on commandline as well as for configuration file
