[PATCH hurd 4/5] hurd: add `proc_make_task_namespace'

[Justus Winter]

Add a new RPC to the process protocol to create task namespaces.
These can be used by an unprivileged process to claims the
responsibility to manage all tasks in this namespace.  Any task
created in this namespace will automatically be declared a child of
the root process, and a `mach_notify_new_task' message is sent to a
given port.  If the root process dies, the proc server will terminate
all tasks in the namespace.

* hurd/process.defs (proc_make_task_namespace): New RPC.
