Maysam Yabandeh 36651d14ee Moving static AdaptationContext to outside function 
Summary:
Moving static AdaptationContext to outside function to bypass tsan's false report with static initializers.

It is because with optimization enabled std::atomic is simplified to as a simple read with no locks. The existing lock produced by static initializer is __cxa_guard_acquire which is apparently not understood by tsan as it is different from normal locks (__gthrw_pthread_mutex_lock).

This is a known problem with tsan:
https://stackoverflow.com/questions/27464190/gccs-tsan-reports-a-data-race-with-a-thread-safe-static-local
https://stackoverflow.com/questions/42062557/c-multithreading-is-initialization-of-a-local-static-lambda-thread-safe

A workaround that I tried was to move the static variable outside the function. It is not a good coding practice since it gives global visibility to variable but it is a hackish workaround until g++ tsan is improved.
Closes https://github.com/facebook/rocksdb/pull/2598
