  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).

  TESTED=./python -E -tt ./Lib/test/regrtest.py -uall (both debug and opt modes)
    in opt mode:
    valgrind -q --leak-check=yes --suppressions=Misc/valgrind-python.supp \
      ./python -E -tt ./Lib/test/regrtest.py -uall,-bsddb,-compiler \
                          -x test_logging test_ssl test_multiprocessing
    valgrind -q --leak-check=yes --suppressions=Misc/valgrind-python.supp \
      ./python -E -tt ./Lib/test/regrtest.py test_multiprocessing
    for i in `seq 1 4000` ; do
      LD_PRELOAD=~/local/lib/libfailmalloc.so FAILMALLOC_INTERVAL=$i \
          ./python -c pass
    done

  At least some of these fixes should probably be backported to 2.5.

bits shared by the stringobject and unicodeobject implementations (and
possibly other modules, in a not too distant future).

the stuff in here is included into relevant places; see the individual
source files for details.

--------------------------------------------------------------------
the following defines used by the different modules:

STRINGLIB_CHAR

    the type used to hold a character (char or Py_UNICODE)

STRINGLIB_EMPTY

    a PyObject representing the empty string

int STRINGLIB_CMP(STRINGLIB_CHAR*, STRINGLIB_CHAR*, Py_ssize_t)

    compares two strings. returns 0 if they match, and non-zero if not.

Py_ssize_t STRINGLIB_LEN(PyObject*)

    returns the length of the given string object (which must be of the
    right type)

PyObject* STRINGLIB_NEW(STRINGLIB_CHAR*, Py_ssize_t)

    creates a new string object

STRINGLIB_CHAR* STRINGLIB_STR(PyObject*)

    returns the pointer to the character data for the given string
    object (which must be of the right type)

int STRINGLIB_CHECK_EXACT(PyObject *)

    returns true if the object is an instance of our type, not a subclass.

STRINGLIB_MUTABLE

    Must be 0 or 1 to tell the cpp macros in stringlib code if the object
    being operated on is mutable or not.
