Add a new type of VM object: OBJT_SG. An OBJT_SG object is very similar to
a device pager (OBJT_DEVICE) object in that it uses fictitious pages to provide aliases to other memory addresses. The primary difference is that it uses an sglist(9) to determine the physical addresses for a given offset into the object instead of invoking the d_mmap() method in a device driver.
