Mark Johnston 99127fd103 libvmmapi: Use the vmmctl device file to create and destroy VMs
This deprecates the vm_create() and vm_open() interfaces and introduces
vm_openf(), which takes flags controlling its behaviour.  In particular,
it will optionally create a VM first, and it can optionally reinitialize
an existing VM.  This enables some simplification of existing consumers.
