* sync.c (pthread_join): Save valueptr arg in joinvalueptr for

	pthread_exit() to use.

	* private.c (_pthread_new_thread_entry): Initialise joinvalueptr to
	NULL.

	* create.c (_pthread_start_call): Rewrite to facilitate joins.
	pthread_exit() will do a longjmp() back to here. Does appropriate
	cleanup and exit/return from the thread.
	(pthread_create): _beginthreadex() now passes a pointer to our
	thread table entry instead of just the call member of that entry.

	* implement.h (_pthread_threads_thread): New member
	void ** joinvalueptr.
	(_pthread_call_t): New member jmpbuf env.

	* exit.c (pthread_exit): Major rewrite to handle joins and handing
	value pointer to joining thread. Uses longjmp() back to
	_pthread_start_call().
