This refactors out a very common pattern of formatting "%s: %s" with e.function.c_str() and strerror( e.the_errno ) into just the what() method of NetworkException. It's also a prerequisite for making cleaner public API for any exceptions we throw, and allows us to more easily get exceptions passed back to us to handle.
