Please review a fairly simple change to have javadoc set a `class`
attribute on the `<body>` element on every generated page. Providing the
value will make it possible/easier to override styles on different types
of pages.
In terms of implementation, this is very similar to setting the
`generator` in a `<meta>` element in the `<head>` element of a page, as
done recently in JDK-8218998. However, while "generator" has more of a
tracing/debugging feel to it, class names that are intended for use in a
stylesheet deserve to be end-user-friendly, and (eventually)
documented/specified.
Most names are generated automatically from the implementation class
name, which catches most uses. The name generation is done in a new
method, which allows it to be overridden if ever that becomes necessary.
Some outlier uses don't use `HtmlDocWriter.getBody` and are fixed up
locally. The frame-related sites will eventually be removed, when
support for frames is removed; the remaining sites should be brought in
line with the rest of the code, but that would be a separate RFE.
Some tests, which included `<body>` in their golden text needed to be
updated in the obvious way. The primary new test leverages the
recently-added TestMetadata.java class, which already generates all the
requisite test files: the new `testBodyClasses()` method is a
copy/edit/paste of the existing `testGenerator` feature.
