mq: explicitly tests for None
Changeset
fd3d8eb7f545 removed the mutable default value, but did not explicitly
tested for None. Such implicit testing can introduce semantic and performance
issue. We move to an explicit testing for None as recommended by PEP8:

parsers: handle refcounting of "parents" consistently
Py_None can be refcounted like any other Python object. So

py3: make py3 compat.iterbytestr simpler and faster
With Python 3.4.3, timit says 11.9 usec-> 6.44 usec. With Python
3.6.0, timeit says 14.1 usec -> 9.55 usec.
py3: optimize py3 compat.bytechr using Struct.pack
With Python 3.4.3, timeit says 0.437 usec -> 0.0685 usec. With Python
3.6, timeit says 0.157 usec -> 0.0907 usec. So it's faster on both
versions, but the speedup varies a lot.
Thanks to Gregory Szorc for the suggestion.
