do not call g_thread_init() for glib >= 2.31
glib >= 2.31 always enables thread support and g_thread_supported() is #defined to 1, there's no need to call g_thread_init() anymore, and it definitely does not need to report error which never happens. Keep code for old < 2.31 glibc anyway for now, just #ifdef it differently.
