RFR: JDK-8200363 Add javadoc command line setting to fail on warnings

[Hannes Wallnöfer]

Hi Jon,

This looks good. I just found a few minor things to clean up:

- in ToolOptions.java the definitions of the rejectWarnings field and method both have comments mentioning the old -Xwerror option. These should be updated to refer to the new -Werror option

- main.opt.Xold.desc property should probably also be removed from javadoc_ja.properties and javadoc-zh_CN.properties. It is also documented in share/man/javadoc.1

The old name is retained as a alias "for a while" but since it is an undocumented option it may be removed at any time, and perhaps in the next release after this change (i.e. 16.)
