Implement Web Workers client-side API

The implementation is experimental, and disabled by default. It doesn't quite match the
published draft, being influenced by further WHATWG discussions.

This only implements the client-side API, and does not actually create any threads or
global contexts yet.

  • DerivedSources.make: Added DedicatedWorker. SharedWorker is not implemented yet, as I'm still not sure if having separate classes for these helps at all.
  • WebCore.xcodeproj/project.pbxproj: Added new files.
  • bindings/js/JSDOMWindowBase.cpp: (jsDOMWindowBaseWorker): (WebCore::JSDOMWindowBase::put): (setJSDOMWindowBaseWorker): Added window.Worker constructor. Moved JSXSLTProcessorConstructor.h include out of ifdef to match prevailing style.
  • bindings/js/JSDedicatedWorkerConstructor.cpp: Added.
  • bindings/js/JSDedicatedWorkerConstructor.h: Added.
  • bindings/js/JSDedicatedWorkerCustom.cpp: Added. The implementation of event listeners are left custom intentionally, for easier implementation of listeners that are not tied to any Document in the future.
  • dom/DedicatedWorker.cpp: Added.
  • dom/DedicatedWorker.h: Added.
  • dom/DedicatedWorker.idl: Added. Added an implementation that can only load requested scripts for now.
