Allow global config settings to be defined in multiple Config classes. For example, this means that libutil can have settings and evaluator settings can be moved out of libstore. The Config classes are registered in a new GlobalConfig class to which config files etc. are applied. Relevant to https://github.com/NixOS/nix/issues/2009 in that it removes the need for ad hoc handling of useCaseHack, which was the underlying cause of that issue.
