* inet/test-ifaddrs.c (main: addr_string): Handle null SA.
	Grok AF_LINK if defined.
	From Momchil Velikov <velco@fadata.bg>.

	* sysdeps/gnu/ifaddrs.c (getifaddrs): If ioctl fails for netmask,
	brdaddr, or dstaddr, just set those pointers to null and don't fail.
	Reported by Momchil Velikov <velco@fadata.bg>.

	* sysdeps/generic/ifreq.h (__if_nextreq) [_HAVE_SA_LEN]: If sa_len
	is > sizeof IFR->ifa_addr, advance past the whole longer length.
	(__ifreq): Count up NIFS that way too.
	Reported by Momchil Velikov <velco@fadata.bg>.

	* sysdeps/mach/hurd/lchmod.c: Include <fcntl.h>.
