libauthsrv: export common readcons() routine and introduce PASSWDLEN constant

Browse source 
drawterm, factotum, secstore and the auth commands
all had ther own implementation of readcons. we
want to have one common function for this to avoid
the duplication, so putting that in libauthsrv.

introduce PASSWDLEN which makes the use more explicit
than ANAMELEN.
