Please review a conceptually simple review to encapsulate the fields
holding the values of doclet options, in the BaseOptions and HtmlOptions
classes.
The encapsulation was done with an IDE. The fields are all changed to
private access; the access methods are package-private by default, and
public when necessary, although in general, there is no problem if it is
determined they should all have public access. This is the same policy
as was done for ToolOptions, currently in review.
Some fields need public "setters". These were added manually.
In a few places, code was simplified manually, joining short lines, or
replacing `configuration.getOptions()` with just `options`.
This is intended to be the last in the current round of option-code
cleanup, for now, although I think there is scope for future work to
rationalize the names of the fields and corresponding accessor methods.
