[bug-inetutils] talkd and ACL

[Mats Erik Andersson]

Dear all,

I have taken the liberty to update talkd with ACL capacity,
building on ground work lying in fallow since years back.

My analysis lead me to claim that the existing ACL code
was completely non-functional, so I have implemented a
reinterpreted mechanism. I feel somewhat strengthened
in this venture, as there was absolutely no documentation
regarding ACL within talkd, so it should be without risk to
change the modes according to my imagination. It remains
to see whether Sergey raises any objections.

Best regards,
  Mats
