* hurd/process.defs (proc_set_init_task): New procedure.
* hurd/process_reply.defs (proc_set_init_task): Likewise.
* hurd/process_request.defs (proc_set_init_task): Likewise.
* include/pids.h: Add HURD_PID_INIT as 1, adjust others accordingly.
* init/init.c (start_child): Register the child task.
* proc/proc.h (init_proc): New variable.
(create_startup_proc): Rename to create_init_proc.
* proc/main.c (main): Create placeholder proc object for pid 1.
* proc/mgt.c: Use init_proc instead of startup_proc, as the former is
the new root of the process tree.
(create_startup_proc): Rename to create_init_proc.
(S_proc_set_init_task): New function.
