  Fix:
   * crashes on memory allocation failure found with failmalloc
   * memory leaks found with valgrind
   * compiler warnings in opt mode which would lead to invalid memory reads
   * problem using wrong name in decimal module reported by pychecker

  Update the valgrind suppressions file with new leaks that are small/one-time
  leaks we don't care about (ie, they are too hard to fix).

  ctypes takes some liberties when creating python types: it modifies the types'

  Now we try to modify the type with more "official" functions.
