QEMU e820 reservation patch


Kevin and I have agreed on the approach for this one now. So here is
the latest version of the patch for QEMU, submitting e820 reservation
entries via fw_cfg.


Use qemu-cfg to provide the BIOS with an optional table of e820 entries.

Notify the BIOS of the location of the TSS+EPT range to by reserving
it via the e820 table.

This matches a corresponding patch for Seabios, however older versions
of Seabios will default to the hardcoded address range and stay
compatible with current QEMU.
