already defined.
Incorporated -lutil library from 4.4-Lite.
* misc/Makefile (extra-libs, libutil-routines): New variables.
* misc/login.c, misc/login_tty.c, misc/logout.c, misc/logwtmp.c,
sysdeps/generic/pty.c: New files for -lutil incorporated from 4.4-Lite.
Support simple, light-weight unwind-protect mechanism for longjmp.
* setjmp/longjmp.c: Call _longjmp_unwind first thing.
* sysdeps/mach/hurd/jmp-unwind.c: New file.
* sysdeps/stub/jmp-unwind.c: New file.

* sysdeps/mips/jmp_buf.h (_JMPBUF_UNWINDS): New macro.
* setjmp/Makefile (routines): Add jmp-unwind.
* hurd/hurd/userlink.h (struct hurd_userlink): Move `next' and
`prevp' members into new substructure `resource'; add another such
substructure `thread' and members `cleanup' (function ptr) and
`cleanup_data' (generic ptr).
(_hurd_userlink_link, _hurd_userlink_unlink): Insert/remove LINK
into the `_hurd_self_sigstate ()->active_resources' list via the
`thread' substructure.
* hurd/hurd/port.h (_hurd_port_cleanup): Declare it.
(_hurd_port_locked_get): Set LINK->cleanup to _hurd_port_cleanup and
LINK->cleanup_data' to the port extracted.
* hurd/hurd/signal.h (struct hurd_sigstate): New member
`active_resources'.
