[hurd,commited] hurd: Avoid exposing all <sched.h> symbols from sys/types.h

[Samuel Thibault <samuel dot thibault at ens-lyon dot org>]

	* bits/sched.h: Include <bits/types/struct_sched_param.h> and move struct
	sched_param definition to it.
	* sysdeps/unix/sysv/linux/bits/sched.h: Likewise.
	* bits/types/struct_sched_param.h: New file.
	* sysdeps/htl/bits/types/struct___pthread_attr.h: Include
	<bits/types/struct_sched_param.h> instead of <sched.h>.
	* posix/Makefile (headers): Add bits/types/struct_sched_param.h.
