o Rename cpu_thread_setup() to cpu_thread_alloc() to better

Browse Source 
communicate that it relates to (is called by) thread_alloc()
o  Add cpu_thread_free() which is called from thread_free()
   to counter-act cpu_thread_alloc().

i386:	Have cpu_thread_free() call cpu_thread_clean() to
	preserve behaviour.
ia64:	Have cpu_thread_free() call mtx_destroy() for the
	mutex initialized in cpu_thread_alloc().
