JDK-8164228 - Test java/io/StringBufferInputStream/OverflowInRead.java fail intermittently
Description
A cleanup pass over code under src/java.base/share/classes/java/io:

- special handling of a null arg can be replaced with using String.valueOf()
- in ObjectInput[Output]Stream checking/putting into map can be replaced with a single call to computeIfAbsent();
- in ObjectStreamClass.getPackageName() one call to String.substing() can be avoided;

and a few other cleanups.

Thanks Alan for clarification. I'll push the fix then once the final round of testing is finished.

Clean-up changes don't need a FC extension request. Aside from code review, there doesn't seem to be anything here that needs special approvals.

FC Extension Request This is a cleanup change, which doesn't change the behavior of the modified classes. The goal is to make the code shorter, cleaner and sometimes a bit faster. The risk level is low, as the changes are either trivial or obvious.
