As a step toward creating a well-defined base API distinct from sys_util, remove the wildcard `pub use sys_util::*` and individuall export just the types, functions, and macros that are intended to be a part of the public base API. The only functional change is that the net namespace is flattened into the top-level base namespace, since it inconsistent with the rest of the API. (sys_util is not affected and still exports mod net, but base does not.)
