* posix/unistd.h [__USE_BSD] (ttyslot): Declare it. * posix/unistd.h [__USE_BSD] (L_SET, L_INCR, L_XTND): Define unless L_SET already defined. * misc/sys/file.h (L_SET, L_INCR, L_XTND): Don't define if L_SET 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/i386/jmp_buf.h (_JMPBUF_UNWINDS): New macro. * 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'. * hurd/port-cleanup.c: New file. * hurd/Makefile (routines): Add port-cleanup. * malloc/malloc.c: Include errno.h.
