/* property definitions
*
* A property structure must be binary-portable, because properties are
* stored in objects, which must be binary-portable. Hence, the internal
* structure of a property header is not a C structure, but a portable
* sequence of bytes. Multi-byte quantities are stored in Intel format.
*
* property number - 2 bytes
* property datatype - 1 byte
* property size - 2 bytes
* property flags - 1 byte
*
* This header is followed immediately by the property value. For
* convenience, a set of macros is defined to provide access to the
* fields of a property header.
