    Use vm_page as the physical memory allocator
    
    This change replaces the historical page allocator with a buddy allocator
    implemented in vm/vm_page.c. This allocator allows easy contiguous 
allocations
    and also manages memory inside segments. In a future change, these segments
    will be used to service requests with special constraints, such as "usable
    for 16-bits DMA" or "must be part of the direct physical mapping".
