Reviewed by David Levin.

Added WorkerReportingProxy for reporting worker state (exceptions, console messages, thread exited) to the parent.

Existing tests are sufficient, as this is only a refactoring.

* GNUmakefile.am:
Added WorkerReportingProxy.h to build.
* WebCore.gypi:
Added WorkerReportingProxy.h to build.
* WebCore.vcproj/WebCore.vcproj:
Added WorkerReportingProxy.h to build.
* WebCore.xcodeproj/project.pbxproj:
Added WorkerReportingProxy.h to build.
* workers/DedicatedWorkerContext.cpp:
* workers/DedicatedWorkerContext.h:
Removed addMessage/forwardException() APIs - now handled by WorkerReportingProxy.
* workers/DedicatedWorkerThread.cpp:
(WebCore::DedicatedWorkerThread::DedicatedWorkerThread):
Changed constructor to pass WorkerReportingProxy to base class.
* workers/DefaultSharedWorkerRepository.cpp:
Updated SharedWorkerProxy to implement WorkerReportingProxy interface.

(WebCore::SharedWorkerProxy::postConsoleMessageToWorkerObject):
(WebCore::SharedWorkerProxy::workerContextClosed):
(WebCore::SharedWorkerProxy::workerContextDestroyed):
(WebCore::DefaultSharedWorkerRepository::workerScriptLoaded):
Now passes in WorkerReportingProxy when creating SharedWorkerThread.

Passes WorkerReportingProxy to base class constructor.
* workers/SharedWorkerThread.h:
Constructor now takes a WorkerReportingProxy.
* workers/WorkerContext.cpp:
(WebCore::WorkerContext::~WorkerContext):
Moved code that calls workerContextDestroyed() into base class so shared workers share this functionality.

Now notifies WorkerReportingProxy when the thread is closing.

Reports exceptions via WorkerReportingProxy.
(WebCore::WorkerContext::addMessage):

Default empty implementation for dedicated workers.

Base interface that contains APIs moved from WorkerObjectProxy.
