Implentation of password and lock commands

[Julien RANC]

Hi everyone,

I am currently trying to get involved actively in the Grub 2 
development. I decided to start by (re)implementing the commands 
"password" and "lock" from Grub Legacy, that are currently missing in 
Grub 2.

For now, I can successfully set a password in the grub.cfg file, read 
it, retrieve it, and block access to command line and edition mode until 
the password is verified. This seems to me a good start :)

I hope I will have a first patch to propose in the weeks to come. As I 
am in the beginning of this implementation, I was wondering if there was 
anything more than what was implemented in Grub Legacy that was 
required, wished, or though about concerning this matter ? All comments 
and suggestions are indeed welcomed.
