x86-64, NUMA: Move NUMA emulation into numa_emulation.c
Create numa_emulation.c and move all NUMA emulation code there. The definitions of struct numa_memblk and numa_meminfo are moved to numa_64.h. Also, numa_remove_memblk_from(), numa_cleanup_meminfo(), numa_reset_distance() along with numa_emulation() are made global. - v2: Internal declarations moved to numa_internal.h as suggested by Yinghai.
