Future patches will add (private) header files in src/ that should not be visible to plugins, so move the "public" ones to a new include/ directory. This is still internal in a sense that the contained files won't be installed for the user. Similarly, the target agnostic offloading library should be built directly in src/. The parent directory is responsible for finding dependencies and including all subdirectories.
