/*
 * In this comment typed properties are those of type DI_PROP_TYPE_UNDEF_IT,
 * DI_PROP_TYPE_BOOLEAN, DI_PROP_TYPE_INT, DI_PROP_TYPE_INT64,
 * DI_PROP_TYPE_BYTE, and DI_PROP_TYPE_STRING.
 *
 * The guessing algorithm is:
 * 1. If the property is typed and the type is consistent with the value of
 *    the property, then the property is of that type. If the type is not
 *    consistent with value of the property, then the type is treated as
 *    alien to prtconf.
 * 2. If the property is of type DI_PROP_TYPE_UNKNOWN the following steps
 *    are carried out.
 *    a. If the value of the property is consistent with a string property,
 *       the type of the property is DI_PROP_TYPE_STRING.
 *    b. Otherwise, if the value of the property is consistent with an integer
 *       property, the type of the property is DI_PROP_TYPE_INT.
 *    c. Otherwise, the property type is treated as alien to prtconf.
 * 3. If the property type is alien to prtconf, then the property value is
 *    read by the appropriate routine for untyped properties and the following
 *    steps are carried out.
 *    a. If the length that the property routine returned is zero, the
 *       property is of type DI_PROP_TYPE_BOOLEAN.
 *    b. Otherwise, if the length that the property routine returned is
 *       positive, then the property value is treated as raw data of type
 *       DI_PROP_TYPE_UNKNOWN.
 *    c. Otherwise, if the length that the property routine returned is
 *       negative, then there is some internal inconsistency and this is
 *       treated as an error and no type is determined.
