/*
* 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.
