Created a DWARFContextState pure virtual class that contains all of the thread sensitive member variables for the DWARFContextClass.

Multi threaded access can be enabled by passing boolean to enable it in the DWARFContext constructor and create static functions. If threading is disabled we instantiate a SingleThreadedState class that contains the ivars and no mutex for thread safety. If we enable threading, a ThreadSafeState is created that uses a mutex to protect access to ivars and calls the work functions in the SingleThreadedState.
