On Linux, we want to attach additional attributes to processes, i.e., the chroot location, the designated UID, and GID. Instead of polluting the generic code with such Linux-specific platform details, I introduced the new 'Native_pd_args' type, which can be customized for each platform. The platform-dependent policy of init is factored out in the new 'pd_args' library. The new 'base-linux/run/lx_pd_args.run' script can be used to validate the propagation of those attributes into core. Note that this patch does not add the interpretation of the new UID and PID attributes by core. This will be subject of a follow-up patch. Related to #510.
