Subject: 	* global.c: New. Global data objects declared here. These
 moved from 	pthread.h.

	* pthread.h: Move implementation hidden definitions into
	implement.h.

	* implement.h: Move implementation hidden definitions from
	pthread.h. Add constants to index into the different handler stacks.

	* cleanup.c (_pthread_handler_push): Simplify args. Restructure.
	(_pthread_handler_pop): Simplify args. Restructure.
	(_pthread_handler_pop_all): Simplify args. Restructure.
