vmm: memory_manager: Implement the Transportable trait

Browse Source 
This implements the send() function of the Transportable trait, so that
the guest memory regions can be saved into one file per region.

This will need to be extended for live migration, as it will require
other transport methods and the recv() function will need to be
implemented too.
