Remove link_addr(3). A function to encode the name of an interface in

a sockaddr_dl is a questionnable interface.  But now it makes it harder
to properly reference ifp becauses of this.

Set sdl_index to the index of the corresponding interface when
constructing a routing message.

Ridding previous libc crank.

-.Dd $Mdocdate: June 5 2013 $
-.Dt LINK_ADDR 3
-.Os
-.Sh NAME
-.Nm link_addr ,
-.Nm link_ntoa
-.Nd elementary address specification routines for link level access
-.Sh SYNOPSIS
-.In sys/types.h
-.In sys/socket.h
-.In net/if_dl.h
-.Ft void
-.Fn link_addr "const char *addr" "struct sockaddr_dl *sdl"
-.Ft char *
-.Fn link_ntoa "const struct sockaddr_dl *sdl"
-.Sh DESCRIPTION
-The
-.Fn link_addr
-function interprets character strings representing
-link-level addresses, returning binary information suitable
-for use in system calls.
-.Fn link_ntoa
-takes
-a link-level
-address and returns an
-.Tn ASCII
-string representing some of the information present,
-including the link level address itself, and the interface name
-or number, if present.
-This facility is experimental and is
-still subject to change.
-.Pp
-For
-.Fn link_addr ,
-the string
-.Fa addr
-may contain
-an optional network interface identifier of the form
-.Dq name unit-number ,
-suitable for the first argument to
-.Xr ifconfig 8 ,
-followed in all cases by a colon and
-an interface address in the form of
-groups of hexadecimal digits
-separated by periods.
-Each group represents a byte of address;
-address bytes are filled left to right from
-low order bytes through high order bytes.
-.Pp
-.\" A regular expression may make this format clearer:
-.\" .Bd -literal -offset indent
-.\" ([a-z]+[0-9]+:)?[0-9a-f]+(\e.[0-9a-f]+)*
-.\" .Ed
-.\" .Pp
-Thus
-.Li le0:8.0.9.13.d.30
-represents an Ethernet address
-to be transmitted on the first Lance Ethernet interface.
-.Sh RETURN VALUES
-.Fn link_ntoa
-always returns a NUL-terminated string.
-.Fn link_addr
-has no return value.
-(See
-.Sx BUGS . )
-.Sh SEE ALSO
-.Xr ifconfig 8
-.Sh HISTORY
-The
-.Fn link_addr
-and
-.Fn link_ntoa
-functions appeared in
-.Bx 4.3 Reno .
-.Sh BUGS
-The returned values for
-.Fn link_ntoa
-reside in a static memory area.
-.Pp
-The function
-.Fn link_addr
-should diagnose improperly formed input, and there should be an unambiguous
-way to recognize this.
-.Pp
-If the
-.Fa sdl_len
-field of the link socket address
-.Fa sdl
-is 0,
-.Fn link_ntoa
-will not insert a colon before the interface address bytes.
-If this translated address is given to
-.Fn link_addr
-without inserting an initial colon,
-the latter will not interpret it correctly.
