Fix hidden API usages to alternative API usages

After moving the code to mainline module, all interactions from
platform should be via APIs or relevant util classes cloned and
jarjar'd within the module.

This change moves such usages to existing APIs or makes a module-utils
copy of such classes to be used independantly in the module.
