  Tests for bin() builtin.  These need to get merged into py3k, which has no tests for bin.

  Improve the implementation of itertools.product()

  * Fix-up issues pointed-out by Neal Norwitz.
  * Add extensive comments.
  * The lz->result variable is now a tuple instead of a list.
  * Use fast macro getitem/setitem calls so most code is in-line.
  * Re-use the result tuple if available (modify in-place instead of copy).

  Issue 1881. Increased the stack limit from 500 to 1500. Also added
  a test for this (and because of this test you'll see in stderr a
  message that parser.c sends before raising MemoryError).
  Thanks Ralf Schmitt.

  Issue 1781. Now ConfigParser.add_section does not let you add a
  DEFAULT section any more, because it duplicated sections with
  the rest of the machinery. Thanks Tim Lesher and Manuel Kaufmann.

/*
Type PyStringObject represents a character string.  An extra zero byte is
reserved at the end to ensure it is zero-terminated, but a size is
present so strings with null bytes in them can be represented.  This
is an immutable object type.

There are functions to create new string objects, to test
an object for string-ness, and to get the
string value.  The latter function returns a null pointer
if the object is not of the proper type.
There is a variant that takes an explicit size as well as a
variant that assumes a zero-terminated string.  Note that none of the
functions should be applied to nil objects.
