Bug 304239 move each core application service to its own package
In M4, some services have their own package, others are provided in core.services. Boris and I talked about moving each service (API) to its own package. Reasons are: - aids with discoverability - helps separate application services from other public API in the core.services package (such as IDisposable, JSONObject) - helps to emphasize that services can be setup and consumed individually - will make it easier to move to separate bundles if that is ever needed This means moving Adapter, Logger, IStatusHandler to their own packages.
bundles/org.eclipse.e4.ui.workbench.swt/src/org/eclipse/e4/ui/workbench/swt/internal/PartRenderingEngine.java
.get(IExtensionRegistry.class.getName());
		IConfigurationElement[] factories = registry
				.getConfigurationElementsFor("org.eclipse.e4.workbench.rendererfactory"); 
		for (int i = 0; i < factories.length; i++) {
			String id = factories[i].getAttribute("id"); 
			if (!curFactoryId.equals(id))
				continue;
			IRendererFactory factory = null;
			try {
				factory = (IRendererFactory) factories[i]
						.createExecutableExtension("class"); 
			} catch (CoreException e) {
				e.printStackTrace();
			}
			if (factory != null) {
				factory.init(context);
				curFactory = factory;
			}
		}
		
		context.set(IPresentationEngine.class.getName(), this);
		
		if (eventBroker != null) {
			eventBroker.subscribe(UIEvents.buildTopic(UIEvents.UIElement.TOPIC,
					UIEvents.UIElement.TOBERENDERED), toBeRenderedHandler);
			eventBroker.subscribe(UIEvents.buildTopic(
					UIEvents.ElementContainer.TOPIC,
					UIEvents.ElementContainer.CHILDREN), childrenHandler);
		}
