Vincenzo Maffione d12c5ef640 bhyve: support for enabling/disabling the net backend 
Extend the net backend interface with two functions, namely netbe_rx_disable()
and netbe_rx_enable(), which can be used by the net device emulators to stop
the backend from invoking the receive callback. This is useful for device
emulators, i.e., on hardware resets or to implement receive backpressure.
The mevent module has been extendede to support the addition of a disabled
event. To prevent race conditions, the net backends will start with receive
operation disabled. A follow-up patch will use the new functionalities in
the virtio-net device.
