Change the ObjExceptionProcessor to write intermediate dumps to a temporary location until they are confirmed by the UncaughtExceptionHandler. Because the exception preprocessor uses heuristics to detect iOS sinkholes, it's possible for an exception to be identified as fatal, but not actual trigger the uncaught exception handler. If the processor detects more than one fatal exception, it will unregister itself and indicate this in the second dump with the key 'MultipleHandledUncaughtNSException'. This changes also consolidates and simplifies some methods in the InProcessHandler.
