eb4cf86c1e
Added a wsrep::thread_service interface to allow application to inject instrumented thread, mutex and condition variable implementation for provider. The interface is defined in include/wsrep/thread_service.hpp. Sample implementation is provided in dbsim/db_threads.[h|c]pp. This patch will also clean up some remaining dependencies to wsrep-API compilation units so that the dependency to wsrep-API is header only. This will extending the provider support to later wsrep-API versions.
