Zack Cornelius e9683f1432 Implement discard for file backed memory 
Add the discard flag to libvirt XML when supported by libvirt and qemu,
and when using file backed memory.

The discard flag causes qemu to discard allocated memory via calling
madvise with MADV_REMOVE when using file backed memory, to prevent
writing out dirty instance memory. This is a significant performance
improvement for shutting down instances that have recently written to
significant portions of their memory.

As qemu and libvirt do not guarantee the discard is run, this cannot be
used for security purposes.
