Had some internal review and I think I'm now taking better care of this
(and the device situation in the other mail). I will send out next
revision soon.

In summary:

- Incrementing platform device's refcount when creating a new VM since
it spawns new file descriptor that could remain open after closing the
main miscdevice.
- Re-organizing vm_manager so it is much more like a library than a
separate device.

Thanks,
