update boot spec to 2.07
Updates for version 2.07 of the boot protocol. This includes:
load_flags.KEEP_SEGMENTS- flag to request/inhibit segment reloads
hardware_subarch - what subarchitecture we're booting under
hardware_subarch_data - per-architecture data
The intention of these changes is to make booting a paravirtualized
kernel work via the normal Linux boot protocol.
