MEDIUM: vars: make var_clear() only reset VF_PERMANENT variables

We certainly do not want that a permanent variable (one that is listed
in the configuration) be erased by accident by an "unset-var" action.
Let's make sure these ones are only reset to an empty sample, like at
the moment of their initial registration. One trick is that the same
function is used to purge the memory at the end and to delete, so we
need to add an extra "force" argument to make the choice.
