Thread-topic: Enable GNTTABOP_copy hypercall for HVMs

Attached is the patch for enabling the GNTTAB_copy hypercall for HVMs. For 64 bit guests the grant_table.c functionality is used as is done by PVs but for 32 bit guests on 64 bit Xen, the compat/grant_table.c functionality is used.

This patch applies cleanly on the latest xen-unstable cset.
