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.
