Update cython package to 0.9.6.11

[robertwb]

http://sage.math.washington.edu/home/robertwb/cython/

everything passes with sage -testall

Main improvements:

• PyObject_CallObject -> PyObject_Call (up to 5% speed increase for python function calls)
• More correct .pyx file annotation (the click-able yellow lines)
• Better support for non-GC objects
• Optimized tp_new/dealloc/traverse/clear slots (similar to our first attempt to speed up integers, but globally)
• Re-enable pre-import (e.g. from sage.all import *)
• __cinit__ (a.k.a __new__) can have optimized signature __new__(self) regardless of __init__ params
• correct overflow error handling for all c int types (before just long was handled correctly)
• (optional) for i in range(...) -> for i from ... conversion
• several minor bug fixes
• cleaned up spkg

With Sage 2.10 [more or less final] I get:

gcc -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -fPIC -I/scratch/mabshoff/release-cycle/sage-2.10.alpha4/local//include -I/scratch/mabshoff/release-cycle/sage-2.10.alpha4/local//include/csage -I/scratch/mabshoff/release-cycle/sage-2.10.alpha4/devel//sage/sage/ext -I/scratch/mabshoff/release-cycle/sage-2.10.alpha4/local/include/python2.5 -c sage/libs/pari/gen.c -o build/temp.linux-x86_64-2.5/sage/libs/pari/gen.o -w
sage/libs/pari/gen.c: In function ‘__pyx_tp_clear_4sage_4libs_4pari_3gen_PariInstance’:

sage/libs/pari/gen.c:33069: error: invalid lvalue in assignment
error: command 'gcc' failed with exit status 1
sage: There was an error installing modified sage library code.

This corresponds to:

static int __pyx_tp_clear_4sage_4libs_4pari_3gen_PariInstance(PyObject *o) {
  struct __pyx_obj_4sage_4libs_4pari_3gen_PariInstance *p = (struct __pyx_obj_4sage_4libs_4pari_3gen_PariInstance *)o;
  PyObject* tmp;
  if (__pyx_ptype_4sage_9structure_11parent_base_ParentWithBase->tp_clear) {
    __pyx_ptype_4sage_9structure_11parent_base_ParentWithBase->tp_clear(o);
  }
  tmp = ((PyObject*)p->ZERO);
  ((PyObject*)p->ZERO) = Py_None; Py_INCREF(Py_None); [line 33063]
  Py_XDECREF(tmp);
  tmp = ((PyObject*)p->ONE);
  ((PyObject*)p->ONE) = Py_None; Py_INCREF(Py_None);
  Py_XDECREF(tmp);
  tmp = ((PyObject*)p->TWO);
  ((PyObject*)p->TWO) = Py_None; Py_INCREF(Py_None);
  Py_XDECREF(tmp);
  return 0;
}

New Cython package up at the same url which should resolve this issue.

I can confirm that the latest cython.spkg completes a sage -ba without issues.
