HVM SMBIOS support 0/6

This series of patches adds support for SMBIOS to HVM domU's. This is needed by many systems management applications, most often to get a useful UUID inside of an HVM domU.

They have been tested on changeset
10486:5610d916ad1be231bd6b6c7ae26665374623a90c
of xen-unstable.

Any comments or help would be greatly appreciated.
