* sysdeps/unix/sysv/linux/bits/sched.h: Declare unshare.

Browse Source 
* sysdeps/unix/sysv/linux/Versions [libc, GLIBC_2.4]: Export
	unshare.
	* sysdeps/unix/sysv/linux/syscalls.list: Add unshare syscall.

	* sysdeps/unix/Makefile ($(objpfx)stub-syscalls.c): Add some
	preprocessor magic so that the compiler won't see the prototypes
	for the functions we are defining as stubs.
