Move the translation from pages to MiB out of XendNode and into the xc layer.
xc has access to the page size for the platform and the Python layer does not,
so there was a hardcoded "/ 256" in there.
Rename the "memory" physinfo parameter to "total_memory", to match the usage
elsewhere.
Tidy the code generating the SXP for xm info.
