Locate QEMU SMBIOS data in fw_cfg and install it via the SMBIOS protocol. Starting with qemu-2.1, on pc/x86 machines of type >= 2.1, full SMBIOS tables are generated and inserted into fw_cfg (i.e., no per-field patching of locally generated structures is required). Aside from new code to extract a SMBIOS blob from fw_cfg, this patch utilizes the pre-existing infrastructure (already used by Xen) to handle final SMBIOS table creation.
