libxl: introduce XSM relabel on build
Allow a domain to be built under one security label and run using a
different label. This can be used to prevent the domain builder or
control domain from having the ability to access a guest domain's memory
via map_foreign_range except during the build process where this is
required.
Example domain configuration snippet:
seclabel='customer_1:vm_r:nomigrate_t'
init_seclabel='customer_1:vm_r:nomigrate_t_building'
Note: this does not provide complete protection from a malicious dom0;
mappings created during the build process may persist after the relabel,
and could be used to indirectly access the guest's memory. However, if
dom0 correctly unmaps the domain upon building, a the domU is protected
against dom0 becoming malicious in the future.
