Restore the x86 PV specific parts.  The X86_PV_INFO, the P2M_FRAMES,
SHARED_INFO, and VCPU context records.

The localise_page callback is called from the common PAGE_DATA code to
convert PFNs in page tables to MFNs.

Page tables are pinned and the guest's P2M is updated when the stream is
complete.
