Added device_open_new and device_open_new_request and reused the old MiG
ID for xxx_device_set_status which has not been in used in the past
decade.
Note that device_open_new is gated on defining
DEVICE_ENABLE_DEVICE_OPEN_NEW because otherwise some hurd servers
wouldn't compile anymore unless patched. This macro allows us to control
the rollout.

It would be very tricky for the server to manage deallocation for
device_read, and does not seem useful anyway. device_reply.defs already
has it.
* include/device/device.defs (device_read): Add dealloc flag for the data
array.

Honor a new macro `MACH_PAYLOAD_TO_PORT' to inject a translation

`mach_port_t'.

`MACH_PAYLOAD_TO_PORT'.
* include/device/device.defs (reply_port_t): Likewise.
* include/device/device_reply.defs (reply_port_t): Likewise.

Previously, every userspace server implementing the device protocol
filtered the device definitions to replace the device_t type with
mach_port_send_t to make the device argument of device_open
polymorphic. Rather than doing that, which makes it impossible to use
translation functions, fix the definition of device_open.
* include/device/device.defs (device_open): Redefine the device
argument to make it polymorphic unless a outran function is specified.
