Replace the use of rte_atomic.h types and functions, instead use GCC
supplied C++11 memory model builtins.
This series covers the libraries and drivers that are built on Windows.
The code has be converted to use the __atomic builtins but there are
additional during conversion i notice that there may be some issues
that need to be addressed.
I'll comment in the patches where my concerns are so the maintainers
may comment.
v3:
* style, don't use c99 comments
v2:
* comment code where optimizations may be possible now that memory
order can be specified.
* comment code where operations should potentially be atomic so that
maintainers can review.
* change a couple of variables labeled as counters to be unsigned.
