large changes to fix the following bugs: 82684, crash manually clearing breakpoint *actually* clearing mValid in jsdScript::Invalidate fixed this one. 85636, assertions on quiting venkman jsdService::Off now disconnects the hooks into JSD, to avoid calling back into js after that. It also processes any pending script delete events that occurred during the last GC. The code to process the gPendingScripts list has been factored out of the gc callback. Processing the dead script list allows us to properly finalize all of the jsdIScript object, which seems to clear up the "gc roots exist at shutdown" assertions. In effect, these changes get rid of *all* of the jsd related assertions on exit. Added isOn attribute to jsdIService. Added isValid attribute to jsdIScript. We now prefetch appropriate properties from the underlying JSDScript, so that it's available after the script is Invalidate()d moved jsdService constructor to jsd_xpc.h Save the runtime passed to OnForRuntime so we can use it to clear the GC Gallback in Off().
