[svn-r3520] Purpose:

    Code checkpoint
Description:
    Checkpointing generic property code before removing the older [non-generic]
    property list implementation and switching all the property lists to use
    the generic code.

    Generic properties are feature complete and as fully tested as I can
    determine.
Platforms tested:
    FreeBSD 4.2 (hawkwind)
