Is DefaultMQPullConsumer.pull thread safe?

[Frodez]

I need to use the function:

PullResult DefaultMQPullConsumer::pull(const MQMessageQueue& mq, const std::string& subExpression, int64 offset, int maxNums)

And I need it for concurrent use. I have navigated several issues, like #141 , but there is no information about whether this function is thread safe.

@Frodez It is thread-safe.
