Fix for #5755 -- making zaml serialization robust over projected objects

The core problem arose when the fix for #5048 in 31118fe85aca4 introduced a
hook to replace objects dynamically durring serialization so that they could be
projected / rewritten to a different form for backward compatability.  The
serialization code assumed that all objects being serialized would remain valid
until the serialization was complete, but nothing retained a copy of the
temporary objects created in the hook.

To resolve this, the serialization layer now maintains a ref to each such object
and clears them (to allow GC) after serialization is complete.
