dnprogs package: Send libdnet/dnet_htoa errors messages to stderr rather than stdout

[Francois-Xavier Le Bail <devel.fx.lebail@orange.fr>]

Hi,

I suggest to apply this patch in dnprogs package:

http://linux-decnet.cvs.sourceforge.net/viewvc/linux-decnet/dnprogs/libdnet/dnet_htoa.c?view=patch&r1=1.2&r2=1.3&sortby=date

(Found using the libdnet library with the tcpdump tool, I see that the errors messages of dnet_htoa
function goes in stdout rather than stderr (example: missing /etc/decnet.conf).

Greetings,

Francois-Xavier Le Bail
