replace mach_port_t with mach_port_name_t

This is a cleanup following the introduction of mach_port_name_t.
The same set of changes is applied to all files:
- rename mach_port_t to mach_port_name_t where a port name is used,
- use MACH_PORT_NAME_NULL and MACH_PORT_NAME_DEAD where appropriate,
- use invalid_port_to_name() and invalid_name_to_port() for conversion
  where appropriate,
- use regular copyout() insted of copyout_port() when we deal with
  mach_port_name_t already before copyout,
- use the new helper ipc_kmsg_copyout_object_to_port() when we really
  want to place a port name in the space of a mach_port_t.

* include/mach/notify.h: Likewise
* ipc/ipc_entry.c: Likewise
* ipc/ipc_kmsg.c: Likewise
* ipc/ipc_kmsg.h: Likewise, and add ipc_kmsg_copyout_object_to_port()
* ipc/ipc_marequest.c: Likewise
* ipc/ipc_object.c: Likewise
* ipc/ipc_port.c: Likewise
* ipc/ipc_space.h: Likewise
* ipc/mach_msg.c: Likewise
* ipc/mach_port.c: Likewise
* kern/exception.c: Likewise
* kern/ipc_mig.c: Likewise
