register an ini-file option.

        :name: name of the ini-variable
        :type: type of the variable, can be ``pathlist``, ``args``, ``linelist``
               or ``bool``.
        :default: default value if no ini-file option exists but is queried.

        The value of ini-variables can be retrieved via a call to
        :py:func:`config.getini(name) <_pytest.config.Config.getini>`.
