Code structure seems sidetracked

To quote the project description:
"This repository contains an OS abstraction layer. ... This abstraction layer is mainly focused on threading functionality."

And yet the newly added FreeRTOS code includes a whole package with something that looks like io (file) functions, main files and linker scripts. This is not something that can be outsourced to a black box libraries. And it has nothing to do with "threading".
