  Issue #4580: slicing of memoryviews when itemsize != 1 is wrong.
  Also fix len() to return number of items rather than length in bytes.

  I'm sorry it was not possible for me to work on this without reindenting
  a bit some stuff around. The indentation in memoryobject.c is a mess,
  I'll open a separate bug for it.
