Kernel+LibC: Turn errno codes into a strongly typed enum
..and allow implicit creation of KResult and KResultOr from ErrnoCode. This means that kernel functions that return those types can finally do "return EINVAL;" and it will just work. There's a handful of functions that still deal with signed integers that should be converted to return KResults.
