TopicPartition_str0 broken on Mac OS X #73
Description
This one is minor but annoying...
On Mac OS X 10.10.5, Python 2.7.9:
>>> from confluent_kafka import TopicPartition
>>> print TopicPartition('topic')
TopicPartition{topic=topic,partition=-1,offset=%lld,error=%s}
On Ubuntu Python 2.7.6
>>> from confluent_kafka import TopicPartition
>>> print TopicPartition('topic')
TopicPartition{topic=topic,partition=-1,offset=-1001,error=None}
I tried to debug this a little and the issue seems to be that mac generates "%lld" and ubuntu generates "%ld" from "PRId64". PyUnicode_FromFormat (v2) does not support "%lld" (was added in v3.2)
