lguest: per-vcpu lguest pgdir management
this patch makes the pgdir management per-vcpu. The pgdirs pool is still guest-wide (although it'll probably need to grow when we are really executing more vcpus), but the pgdidx index is gone, since it makes no sense anymore. Instead, we use a per-vcpu index. Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
