Bug #17514920 MYSQL_THREAD_INIT() CALL WITHOUT MYSQL_INIT() IS CRASHING IN WINDOWS

Browse Source 
It is error to call mysql_thread_init() before libmysql is initialized with mysql_library_init(). Thus to fix this bug we need to detect if library was initialized and return error result if mysql_thread_init() is called with uninitialized library.

Fixed by checking my_thread_global_init_done and returning nonzero if the library is not initialized.
