Vladimir, David,

I've (forced) pushed a smaller version of the renaming. instead of removing `sun.hotspot` classes, it copies them to `jdk.test.whitebox` (w/ `s.h.parser.DiagnosticCommand` being removed as it's used in WhiteBox signature and it was easier to update a few tests that use it), updates hotspot code to register native methods for both `sun.hotspot.WhiteBox` and `jdk.test.whitebox.WhiteBox` classes. To make it easier and not to introduce extra dependency, I've made it impossible to use `s.h.WB` w/ a security manager enabled, otherwise there would be a dependency b/w `s.h.WB` and `j.t.w.WB$WhiteBoxPermission` or there would be 2 permissions. There are no open JDK tests that are impacted by this limitation.

With minor tweaks in closed source, the patch successfully passes Oracle's tier1-4.
