A bit of a redesign.
Sessions and Ports are now detached from each other. HLE services are handled by means of a SessionRequestHandler class, Interface now inherits from this class. The File and Directory classes are no longer kernel objects, but SessionRequestHandlers instead, bound to a ServerSession when requested. File::OpenLinkFile now creates a new session pair and binds the File instance to it.
