I don't see a better name than SIZEOF:
  - The terms "length", "count", "used" etc. allude to the used portion
    of an array, not its allocated size.
  - "cardinality" is longer, for no added value.
  - The word "end_index" would be reasonable if the only use was in
    'for' loops. But when you concatenate two arrays, and you've got to write
      XNMALLOC (END_INDEX (a1) + END_INDEX (a2), type)
    you realize that it is not capturing the entire semantics.
