Anton Belousov 9f114abb37 hvmloader: add new SMBIOS tables (7, 8, 9, 26, 27, 28) ...

Some SMBIOS tables are used by certain malware families to detect virtualized
environments via WMI queries.

To improve stealth for sandboxing purposes, this patch adds support
for populating these SMBIOS tables from an external binary specified
via the "smbios_firmware" domain config option:

* 7 - Cache Info
* 8 - Port Connector
* 9 - System Slots
* 26 - Voltage Probe
* 27 - Cooling Device
* 28 - Temperature Probe

If particular table is absent in binary file, then it will not be mapped to
memory. This method works for Windows domains as tables 7,8,9,26,27,28 are not
critical for OS boot and runtime. Also if "smbios_firmware" parameter is not
provided, these tables will be skipped in write_smbios_tables function.
