        * modules/pam_selinux/pam_selinux.c (config_context): Do not
        ask for the level if use_current_range is set.
        (context_from_env): New function to obtain the context from
        PAM environment variables.
        (pam_sm_open_session): Call context_from_env() if env_params option
        is present. use_current_range now modifies behavior of the
        context_from_env and config_context options.
        * modules/pam_selinux/pam_selinux.8.xml: Describe the env_params
        option. Adjust description of use_current_range option.
