[BUG] Make Thread Counter Thread Safe #2973
Description
The int srt::CSndQueue::m_counter is just a global variable used to construct a name for a thread. However, it is not thread safe unlike srt::sync::atomic<int> srt::CRcvQueue::m_counter(0).
Even though the CRcvQueue::m_counter is atomic, some weird thread names were observed on a platform (MX4) not supporting atomics directly, but using the atomic primitives supplied by srt in atomic.h as a fallback solution.
