Clean up Improved(Input|Output)Stream

Two main changes:

- Replaced getClass().getSimpleName() in the logs with a constructor-given name. Right now what we have is a lot of identical classes with slightly different names so that the logs would be different. With this change - we can later get rid of a lot of these classes and replace them with simple wrappers.

- Removed the "expected" feature. Only Tar uses it - and it can override onClose to do that (that's what it's there for!)
