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".
