Update constants to nowadays standards
kern/zalloc.c (zone_map_size): Increase to 64MiB.
i386/i386at/model_dep.c (mem_size_init): Reduce cap to 1/6 of memory
space to save room for zalloc area.
linux/src/drivers/block/ide.h (INITIAL_MULT_COUNT): Set to 16.
vm/vm_map.h (VM_MAP_COPY_PAGE_LIST_MAX): Set to 64.
vm/vm_object.c (vm_object_cached_max): Set to 4000.
