This shadow code allocates a fixed pool of memory per domain for
shadowing pagetables and building the phys-to-machine map (the old
shadow code just allocated pages from domheap as it required them).

The new parameter is used in shadow-control dom0 ops to set or get the
size of this pool, and set to NULL for all other operations.

Cheers,

Tim.
