[4.1] 33666d6 Make -msg an alias to -reason

    Make -msg an alias to -reason
    
    When we renamed resp.msg to resp.reason to match RFC and VCL terminology
    we forgot to rename its counterpart. Instead of renaming -msg to -reason
    the former will instead become an alias of the latter. This way it can
    be applied to older branches (modulus inline documentation).
