RFR: JDK-8196202: Javadoc should not generate frames by default

[Jonathan Gibbons]

Please review a small source change and corresponding test updates to 
javadoc,
so that the behavior is to not generate frames by default. (A future 
release will
remove support for frames altogether.)

Most test changes are tiny, and correspond to adding "--frames" to restore
the previous behavior. There should be a followup bug to change the test to
work without the --frames option.  The small test changes are best 
viewed through
Udiffs links. One test has non-trivial changes: TestFramesNoFramesTest.java.

The change is dependent on the CSR being approved.
