	* cleanup.c (_pthread_cleanup_push): Implement.
	(_pthread_cleanup_pop): Implement.
	(_pthread_do_cancellation): Implement.
	These are private to the implementation. The real cleanup functions
	are macros. See below.

	* pthread.h (pthread_cleanup_push): Implement as a macro.
	(pthread_cleanup_pop): Implement as a macro.
	Because these are macros which start and end a block, the POSIX scoping
	requirement is observed. See the comment in the file.

	* exit.c (pthread_exit): Refine the code.

	* create.c (pthread_create): Code cleanup.

	* implement.h (RND_SIZEOF): Add RND_SIZEOF(T) to round sizeof(T)
	up to multiple of DWORD.
	Add function prototypes.

	* private.c (_pthread_getthreadindex): "*thread" should have been
	"thread". Detect empty slot fail condition.
