[New-bugs-announce] [issue21644] Optimize bytearray(int) constructor to use calloc()

[STINNER Victor]

New submission from STINNER Victor:

Python 3.5 has a new PyObject_Calloc() function which can be used for fast memory allocation of memory block initialized with zeros.

I already implemented an optimization, but Stefan Krah found issues in my change:
http://bugs.python.org/issue21233#msg217826

I reverted the optimization in the changeset dff6b4b61cac.
