[PATCH 08/15] use port name type in mach_port_names()

[Luca Dariz]

* ipc/mach_port.c: use mach_port_name_t instead of mach_port_t, since
  they could have different size. Fortunately we can keep the same
  optimization about allocationg memory, since mach_port_type_t has
  the same size as a name.
