Rather than require a dependency on the balloon module, split the functionality that is reused into the core. The balloon module is still required to follow ballooning requests from xenstore or to view balloon statistics in sysfs.

These shared pages can be mapped using the gntdev device or by the kernel in another domain.

To do this, we define our own BIOVEC_PHYS_MERGEABLE. When CONFIG_XEN isn't enabled, or we're not running in a Xen domain, this has identical behaviour to the normal implementation. When running under Xen, we also make sure the underlying machine pages are the same or adjacent.
