Sascha Hauer 90e766a78f 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.

Jean-Christophe PLAGNIOL-VILLARD 27b2336029 digest: make it multi-instance
Now you need to call digest_alloc and when you finish to use it digest_free.

We need this for upcomming aes encryption support and secure boot
as we will need multiple instance of the same digest.
