Bug 178164 Use IEngineTask.status constants and remove unnecessary status variables in EngineTask.
1)Remove following redundant variables in EngineTask used for status info. protected final int RUNNING_STATUS_START = 0; protected final int RUNNING_STATUS_RUNNING = 1; protected final int RUNNING_STATUS_STOP = 2; EngineTask already has access to constants declared in IEngineTask. Use those instead. 2)Remove the unused errorHandlingOption in EngineTask.
