Obtain number of ports in proc and libps
Add (and implement) a proc RPC to obtain the number of Mach ports used
by the target task.
Add infrastructure in libps to read this information.
* hurd/process.defs (proc_getnports): New RPC.
* hurd/process_request.defs (proc_getnports_request): New RPC.
* libps/procstat.c (proc_stat_set_flags): Call proc_getnports RPC if
needed.
* libps/ps.h (proc_stat): New `num_ports' field.
(PSTAT_NUM_PORTS): New macro.
(proc_stat_num_ports): New macro.
* libps/spec.c (ps_get_num_ports): New function.
(ps_num_ports_getter): New variable.
(specs): New entry for `ps_num_ports_getter'.
* proc/info.c (S_proc_getnports): New function.
