([Encoder -_objectWillBeInProgress:]): New method.
([Encoder -_objectNoLongerInProgress:]): New method. Depending on
whether we are doing GNU or OpenStep style forward references one of
these two methods will create a backward reference to the object by
calling -_coderInternalCreateReferenceForObject:. This will effect
whether encoding make forward or backward references to objects in
progress. GNU uses forward references, which is robust even when the
object's -initWithCoder substitutes another object for self.
([Encoder -_encodeObject:withName:isBycopy:isForwardReference:]): Use
new methods. Don't call -_coderInternalCreateReferenceForObject here,
let one of the ...InProgress methods do it.

([Decoder -_coderCreateReferenceForObject:]): Add a debugging message.
([Decoder -_coderCreateReferenceForInterconnectedObject:]):
Autorelease the placeholder object.
([Decoder -_createReferenceBeforeInit]): New method. By default
return NO, for the GNU-style forward references.
([Decoder -decodeObjectAt:anObjPtr:name]): [CODER_OBJECT]: Use new
method; if it returns true, then we are using non-GNU, OpenStep-style
forward references. In this case: (1) don't try to decode the object by
sending +newWithCoder:, in fact, raise an error if the object wanted
to be decoded that way; (2) call _coderInternalCreateReferenceForObject
before sending -initWithCoder, not after; unfortunately this means
that -initWithCoder methods cannot substitute another object for self.
If it returns false, use the more robust GNU style forward references.
The NSGUnarchiver overrides this method to use the OpenStep style.

([Coder +archivedDataWithRootObject:]): Use Archiver class, not
NSArchiver, it matters because now the two classes handle forward
references differently.

ANOBJPTR is NULL, and deal with it using a DUMMY_OBJECT local variable.
Remove CODER_OBJECT_FORWARD_SATISFIER case. In the CODER_OBJECT case,
decode the forward reference number, and deal with it appropriately.

if object satisfies a forward reference *after* encoding it. This is
necessary because the encoding of subobjects may generate forward
references. (In a sense, this undoes the last change, but it is
significantly different in that we test whether the object is in the
object_2_fref table *after* encoding the object; before we looked in
the table before encoding the object.) As a consequence,
the CODER_OBJECT_FORWARD_SATISFIER tag is no longer necessary; this
was used to tag an object before it was encoded, but now we understand
that we cannot know whether this object satisfies a forward reference
until after it has been encoded. Thus, for all objects we encode an
unsigned int after encoding the object itself. This unsigned int is
either the forward reference number of zero, depending on whether this
object satisfies any forward references.
