RFR: 8067127: Tags cleanup [v2]

[Brian Burkhalter]

> Please review this change to update some javadoc tags in the java.io package. The changes are to replace some
> occurrences of <code>some_code</code> with {@code some_code}. Not all such constructs were replaced as being
> infeasible, e.g., tag contains an entity such as <code>*/</code> (DataOutput, Serial), or multiple {@code} tags
> would be needed or the result would be ugly (File). It is unclear whether some of the changes which remove the
> non-breaking space entity ( ) are desirable.  Thanks,  Brian
