Description

In particular, ReflectiveCallerClassUtility should be moved into the API inside the util package. This will provide a nice alternative for making a new Throwable each time.

For an idea on why this can be useful, run the ReflectionBenchmark in log4j-perf and note the differences. It's rather significant.

Since this would go in the util package, it would be a non-public API. It would make sense for some very, very common utility classes like this to be in there.
