Introduce the following three sections for these variables: * Environment variables for '*config' * Environment variables for '{allyes/allmod/allno/rand}config' * Environment variables for 'silentoldconfig' Furthermore this puts MENUCONFIG_MODE next to MENUCONFIG_COLOR into a common section "User interface options for 'menuconfig'".
