Bug #55345, "mysql_library_init causes segfault if executed after calling mysql_library_end"

Browse Source 
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().
