	* acconfig.h, configure.in: Reverted the changes necessary to
	enlarge the system thread for G_THREAD_USE_PID_SURROGATE.

	* gthread.c: Now implement G_THREAD_USE_PID_SURROGATE in gthread.c
	instead of gthread/gthread-posix.c. While the latter has the
	advantage, that it is conceptually cleaner, it makes
	g_thread_self_posix_impl _very_ slow and that hurts
	GStaticRecMutex and other things. So the new version is less
	clean, but faster.

	* gthread-posix.c: Removed the G_THREAD_USE_PID_SURROGATE
	implementation, which is now in gthread.c.
