    kernel - add MAP_SIZEALIGN
    
    * Add a mmap() MAP_SIZEALIGN flag which requests alignment the same
      as the size argument (different from Solaris's MAP_ALIGN which uses
      the address hint).
    
    * Will be used in upcoming libc/stdlib/dmalloc.c work.  The dmalloc code
      will work without it just fine, too..
