The substance of this change is in https://hg.python.org/jython/rev/5e3bd2044a51, and subsequent change sets apply it to new areas of the runtime. It co-exists reasonably well with the existing approach, but the intention is that we use logging directly, as for example in these recent changes to the scopes compiler: https://hg.python.org/jython/rev/443426bd426c .

There is still a mixture of old-style and new-style invocation of logging, and some deprecated use of Options.verbose, but essentially this works now.
