* Formatting string, int, float and complex use the _PyUnicodeWriter API. It
avoids a temporary buffer in most cases.
* Add _PyUnicodeWriter_WriteStr() to restore the PyAccu optimization: just
keep a reference to the string if the output is only composed of one string
* Disable overallocation when formatting the last argument of str%args and
str.format(args)
* Overallocation allocates at least 100 characters: add min_length attribute
to the _PyUnicodeWriter structure
* Add new private functions: _PyUnicode_FastCopyCharacters(),
_PyUnicode_FastFill() and _PyUnicode_FromASCII()
The speed up is around 20% in average.
types. Added a new API function, PyUnicode_TransformDecimalToASCII(),
which transforms non-ASCII decimal digits in a Unicode string to their
ASCII equivalents.
(instances of int, float, complex, decimal.Decimal and
fractions.Fraction) that makes it easy to maintain the invariant that
hash(x) == hash(y) whenever x and y have equal value.
objects. (1) The comparison could incorrectly return True in some cases
(2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
(2) The comparison raised an OverflowError for large integers, leading
to unpredictable exceptions when combining integers and complex objects
in sets or dicts.

Include ieeefp.h (when available) in pyport.h instead of individually in
Objects/floatobject.c and Objects/complexobject.c. This should silence
compiler warnings about implicit declaration of the 'finite' function
on Solaris.
