    loader(8): Update: add more text on kenv vs local variables etc.
     - Add missing kenv variables to assignment white list;
    all kenv variables which are used in loader(8) source are added.
     - Inhibiting loading of acpi(4) needs to use `lunset acpi_load',
    not `unset', as `loadall' uses local variables; ditto for ehci.
     - Add info to loader.8 & help files on variables ($VAR / ${VAR}) in
    command arguments and assignment; these are kenv variables.
     - Add description of vfs.root.realroot
     - Fix some whitespace style(7).
