	* sysdeps/unix/sysv/linux/ia64/ucontext_i.h: New file.

	* sysdeps/unix/sysv/linux/ia64/sys/ucontext.h: Rewrite to make it

	sys/rse.h for "misc" subdir.
	(sysdep_routines): Add __start_context for "stdlib" subdir.

	* sysdeps/unix/sysv/linux/ia64/sys/rse.h: New file (based on
	kernel file of the same name).

	* stdlib/Makefile (tests): Add tst-setcontext.
	* stdlib/tst-setcontext.c: New file (based on a sample program by
	Uli Drepper).
