Make it possible to run valgrind on code linked with the libxc libraries.
Valgrind cannot see when a hypercall has initialised entries in a data
structure, so appropriate memsets have been placed before using dom0_op_t,
privcmd_hypercall_t, and a couple of miscellaneous blocks passed into this

When a foreign page is mapped via a grant reference, it
must also be unmapped explicitly via the grant-table
