tools: VM generation ID save/restore and migrate.
Add code to track the address of the VM generation ID buffer across a
save/restore or migrate, and increment it as necessary.
The address of the buffer is written into xenstore by hvmloader at
boot time. It must be read from xenstore by the caller of
xc_domain_save() and then written back again by the caller of
xc_domain_restore().
Note that the changes to xc_save.c and xc_restore.c are merely
sufficient for them to build.
