Added the future_builtins module, which contains hex() and oct(). These are
the PEP 3127 version of these functions, designed to be compatible with the
hex() and oct() builtins from Python 3.0.  They differ slightly in their
output formats from the existing, unchanged Python 2.6 builtins.  The
expected usage of the future_builtins module is:   from future_builtins

Modified PyOS_ascii_formatd to use at most 2 digit exponents for exponents
with absolute value < 100.  Follows C99 standard.  This is a change on

PyOS_ascii_formatd understands, so that any alterations it does to the
resulting string will be available in stringlib/formatter.h (for
float.__format__).
