Implement new heartbeat code to catch runaway execution of document ECMAScript code. The old code uses JS_SetBranchCallback which is deprecated in new versions of SpiderMonkey. The new code uses setitimer(2) and the JS_SetOperationCallback and JS_TriggerOperationCallback interfaces, introduced in SpiderMonkey 1.8.1. Compatibility with both the old JS_SetBranchCallback and the new interfaces is maintained.
