backdoor by authorized_keys2 leftovers

Hi devs,

recently I had to replace authorized_keys on several systems to
enforce an access policy change.
I was badly surprised that authorized_keys2(!) was still processed,
which allowed some old keys to enter the systems again, because I
wasn't aware of the file's existance on the server and use by sshd,
since this "backward compatibility" isn't documented, not even a
historical reference about "obsolete" or "deprecated".

Maybe it's time to drop the old stuff not to get haunted by such
leftovers again.

Thanks, regards,
