Chromoting is planning to bump up the iOS deployment target to 10.0 before but is blocked by WebRTC because it uses deprecated OSAtomic* APIs. This CL replaces the platform specific Atomic32 implementation and uses C++11's std::atomic instead. Bug: webrtc:8413 Change-Id: Icbd29bb92eec60066589bbabf53e0d50df2f9b0d Reviewed-on: https://webrtc-review.googlesource.com/12740 Commit-Queue: Yuwei Huang <yuweih@google.com> Reviewed-by: Karl Wiberg <kwiberg@webrtc.org> Reviewed-by: Niels Moller <nisse@webrtc.org> Cr-Commit-Position: refs/heads/master@{#20376}
