      Bug #55345, "mysql_library_init causes segfault if executed after calling mysql_library_end"
      
      my_thread_global_end() now sets mysql_thread_basic_global_init_done= 0
      to ensure destroyed mutexes are not reused.
      
      I verified that clearing this flag will not result in the redundant allocation
      of other resources allocated by my_thread_global_init() and
      my_thread_basic_global_init().
     @ mysys/my_thr_init.c
        Clear mysql_thread_basic_global_init_done flag at the end of my_thread_global_end()
