- Arrays can now be externalized and internalized in the same way
dictionaries can.
- Add new "externalize to file" and "internalize from file" functions
to make reading a property list from a file and writing a property
list to a file more convenient.
- Many assertions in the object implementations are gone. Instead,
calling an accessor for one object type with a different object type
as an argument will return a suitable "invalid" value.
- prop_object_type() now returns a new PROP_TYPE_UNKNOWN value if called
with a NULL object.
- Externalized property lists now contain a reference to the Apple XML
plist DTD.
- Add a new prop_ingest(3) facility, which provides a convenient way to
translate a dictionary into an arbitrary binary representation.
adavantage of the immutability of these objects:
Statically allocate a TRUE object and a FALSE object, and simply return
references to those objects for create and copy operations.
prop_dictionary_keysym_equals(), and prop_object_equals() functions.
- Use realloc() where it makes sense. There will be more changes in this
area.
- Add a _prop_object_type structure that is used internally to keep
information about the object types. Decreases the footprint of the
objects slightly by replacing several pointers with just one.

Should we just use "memset(pd, 0, sizeof(*pd));" instead?

I'm not sure if idempotent versions need to be defined for big endian,
as the man page says in that case they are defined idempotent macros.

only done when building for sun2.

Some Makefiles for standalone programs already have it.
