    proc: Hierarchical proc servers.
    
    Previously, a Subhurd's tasks were shown as weird processes in the
    Motherhurd.  This change connects the proc server in the Motherhurd
    with the proc server in the Subhurd, embedding the Subhurd's process
    hierarchy.  Subhurd's processes can now be inspected and debugged like
    any other process.
    
    * NEWS: Update.
    * boot/boot.c (mach_msg_forward): New function.
    (boot_demuxer): Forward messages arriving on the new task notification
    port from the proc server, and forward them to the proc server inside
    the Subhurd via the notification port.
    * proc/info.c (S_proc_task2proc): Relay request for processes in a task
    namespace to the Subhurd's proc server.

    hurd: Use polymorphic port types to return some rights.
    
    Currently, the RPC definitions of two procedures of the process
    subsystem assume that the rights are created from a receive right.
    Similarly, 'proc_getmsgport' assumes that the right is to be copied.
    This needlessly limits the ability to relay the RPC in server code.
    
    This fixes this.  The protocol is unchanged, only the generated server
    stubs assume an additional parameter for the type.
    
    * hurd/process.defs (proc_getmsgport): Make 'msgport' parameter
    polymorphic.
    (proc_task2proc): Make 'proc' parameter polymorphic.
    (proc_pid2proc): Likewise.
    * hurd/process_reply.defs (proc_getmsgport): Likewise.
    (proc_task2proc_reply): Likewise.
    (proc_pid2proc_reply): Likewise.
    * proc/info.c (S_proc_task2proc): Adapt server function.
    (S_proc_pid2proc): Likewise.
    * proc/msg.c (S_proc_getmsgport): Likewise.
