kconfig: new configuration interface (nconfig)

This patch was inspired by the kernel projects page, where an ncurses replacement for menuconfig was mentioned (by Sam Ravnborg). Building on menuconfig, this patch implements a more modern look interface using ncurses and ncurses' satellite libraries (menu, panel, form). The implementation does not depend on lxdialog, which is currently distributed with the kernel.
