SF bug #1085744:  Performance issues with PySequence_Tuple()

* Added missing error checks.
* Fixed O(n**2) growth pattern.  Modeled after lists to achieve linear
  amortized resizing.  Improves construction of "tuple(it)" when "it" is
  large and does not have a __len__ method.  Other cases are unaffected.
