PROTON-2377: [cpp] Make tag_counter in sender.cpp atomic
> [cpp] tag_counter is not used in a thread safe way in sender.cpp
> ----------------------------------------------------------------

> Key: PROTON-2377
> URL: https://issues.apache.org/jira/browse/PROTON-2377
> Project: Qpid Proton
> Issue Type: Bug
> Components: cpp-binding
> Reporter: Rakhi Kumari
> Priority: Major
>
> uint64_t tag_counter = 0 is a global variable, so it might end up giving
> duplicate ids to different threads.
> We need to ensure that a single sender will not send a message with a
> duplicate tag. Thread safety is required to guarantee unique tags.
