login: rework login mechanism
We used to have the login functionality in the /env/bin/init script.
This is hard to review and it's too easy to break the login functionality
with changes to this script. Move the places to ask for a password to
C code where we have only a few places where we have to ask for a password.
Mainly these are run_shell() and the menutree command.
This patch introduces a login() function which will only return if the correct
password has been entered. Following calls will return immediately without
asking for a password again.
