- more consistent naming:
* Versions that hold and manage their own memory:
IListStream, OListStream
* Versions that reference a fixed size external memory:
UIListStream, UOListStream
- use List storage instead of DynamicList within OListStream.
Avoids duplicate bookkeeping, more direct handling of resizing.
