* Legal tristate values are:

* \param keyname Name of the key to look for.
* \param skip Number of values to skip/ignore before returning the value.
* This is used to iterate through the values of a multi-valued key:
* \c 0 for the first value, \c 1 for the 2nd, ... and \c -1 for the last.
* \param name3rd Name of the 3rd state
* \param default_value Default value if section/key is not found, value is no legal boolean,
* or \c skip exceeds the number of values of the key.
* \return Value found / \c default_value
