        Worker exceptions should be printed to console

        * dom/Document.cpp: (WebCore::Document::reportException):
        * dom/Document.h:
        * dom/ScriptExecutionContext.h:
        * dom/WorkerContext.cpp: (WebCore::WorkerContext::reportException):
        * dom/WorkerContext.h:
        Added a reportException() method on ScriptExecutionContext. It forwards the exception info
        up until it finds a Document context, and then it prints it to console.

        * bindings/js/JSEventListener.cpp:
        (WebCore::JSAbstractEventListener::handleEvent): Don't talk to Console directly, use
        ScriptExecutionContext::reportException. Also, fixed a bug where Document::updateDocumentsRendering()
        could be called from workers.
        (WebCore::JSLazyEventListener::parseCode): Moved variable declaration inside if block for clarity.

        * bindings/js/WorkerScriptController.cpp: (WebCore::WorkerScriptController::evaluate):
        Report exceptions to ScriptExecutionContext.

        * dom/WorkerMessagingProxy.cpp:
        (WebCore::MessageWorkerTask::performTask):
        (WebCore::WorkerExceptionTask::create):
        (WebCore::WorkerExceptionTask::WorkerExceptionTask):
        (WebCore::WorkerExceptionTask::performTask):
        (WebCore::WorkerMessagingProxy::postWorkerException):
        * dom/WorkerMessagingProxy.h:
        Added a task for posting exception information.

        * bindings/js/JSDOMBinding.cpp:
        (WebCore::reportException):
        (WebCore::reportCurrentException):
        * bindings/js/JSDOMBinding.h:
        Added helper methods for reporting exceptions via ScriptExecutionContext.

        * page/Console.cpp:
        * page/Console.h:
        Removed methods for directly reporting exceptions to console.

        * bindings/js/JSCustomPositionCallback.cpp:
        (WebCore::JSCustomPositionCallback::handleEvent):
        * bindings/js/JSCustomPositionErrorCallback.cpp:
        (WebCore::JSCustomPositionErrorCallback::handleEvent):
        * bindings/js/JSCustomSQLStatementCallback.cpp:
        (WebCore::JSCustomSQLStatementCallback::handleEvent):
        * bindings/js/JSCustomSQLStatementErrorCallback.cpp:
        (WebCore::JSCustomSQLStatementErrorCallback::handleEvent):
        * bindings/js/JSCustomSQLTransactionCallback.cpp:
        (WebCore::JSCustomSQLTransactionCallback::handleEvent):
        * bindings/js/JSCustomSQLTransactionErrorCallback.cpp:
        (WebCore::JSCustomSQLTransactionErrorCallback::handleEvent):
        * bindings/js/JSCustomVoidCallback.cpp:
        (WebCore::JSCustomVoidCallback::handleEvent):
        * bindings/js/JSCustomXPathNSResolver.cpp:
        (WebCore::JSCustomXPathNSResolver::lookupNamespaceURI):
        * bindings/js/ScheduledAction.cpp:
        (WebCore::ScheduledAction::execute):
        * bindings/js/ScriptController.cpp:
        (WebCore::ScriptController::evaluate):
        * bindings/objc/WebScriptObject.mm:
        (WebCore::addExceptionToConsole):
        Switch to JSDOMBinding methods for reporting exceptions.
