freebsd-skq/usr.sbin/bhyvectl/bhyvectl.c
Robert Wing d4870e3a72 bhyve/snapshot: provide a way to send other messages/data to bhyve 
This is a step towards sending messages (other than suspend/checkpoint)
from bhyvectl to bhyve.

Introduce a new struct, ipc_message - this struct stores the type of
message and a union containing message specific structures for the type
of message being sent.
