Remove OSGIUtils This commit removes OSGIUtils. This class duplicated a lot of functionality from BundleContext, and hides some important details about OSGi such as where the underlying BundleContext comes from. For instance, when developing the Eclipse client, at first the common-core bundle wasn't started. This lead to NPEs in OSGIUtils because it uses the BundleContext of the common-core bundle and not the bundle of the calling class or the bundle containing the requested service. Another problem with OSGIUtils is from several cases in Thermostat where we are using getService instead of getServiceAllowNull, which throws NPEs if the requested service is not registered. Uses of OSGIUtils have been replaced with either a ServiceTracker for long-running tasks (e.g. GUI), or for shell commands using a BundleContext and checking the ServiceReference for null and throwing a meaningful exception.
