Remove the util package's dependency on the config package

This allows us to use util methods from within config, which is a useful thing
to be able to do for, e.g., being able to log errors while loading configuration.
It makes sense that the util package should be at the very base of the
class inheritance hierarchy; config seems logically higher than it.
