sys.stdin.buffer not always available - causes exception

[oberstet]

This is triggered from our unit tests on CPython 3.5.1 (with the binary extension):

autobahn/wamp/test/test_serializer.py:34: in <module>
    from autobahn.wamp import serializer
autobahn/wamp/serializer.py:501: in <module>
    import ubjson
../../../cpy351_6/lib/python3.5/site-packages/ubjson/__init__.py:29: in <module>
    from .encoder import dump, dumpb, EncoderException  # noqa
ubjson/encoder.py:23: in init ubjson.encoder (ubjson/encoder.py3.c:6793)
    ???
ubjson/compat.py:64: in init ubjson.compat (ubjson/compat.py3.c:1403)
    ???
E   AttributeError: 'DontReadFromInput' object has no attribute 'buffer'

When I (manually) disable the extension (by commenting ext_modules in setup.py):

autobahn/wamp/serializer.py:501: in <module>
    import ubjson
../../../cpy351_6/lib/python3.5/site-packages/py_ubjson-0.8.3-py3.5.egg/ubjson/__init__.py:29: in <module>

actually, this might be a pytest issue .. still investigating

[vtermanis]

I think I've addressed the issue in the referenced commit on the dev-contrib branch. Could you please check whether this solves the problem you've described here?

[oberstet]

@vtermanis can confirm, that works!
