Hi all,

Here is my first patch for Grub2, so I hope it won't be too bad, and by 
advance, all my apologies for the probable errors ;-) So, please, 
comment gently...

These 2 patch add support for the 'password' command, with the syntax I 
proposed in my mail from August 1st.

Just a few remarks:
1. if you use several 'password' commands in the grub.cfg, only the last 
one will be valid.
2. To use MD5 passwords, you _MUST_ put quotes around the password. For 
example:
password --md5 '$1$WAso4$Z93ELTjxbgLaXvhSF/7cZ/' --> This works fine
password --md5 $1$WAso4$Z93ELTjxbgLaXvhSF/7cZ/ --> no quotes, don't work
3. passwords are limited to 64 chars.

The first patch (patch_1.txt) contains the implementation itself of 
password management, and MD5 routines (based on the MD5 routines from 
Grub Legacy)

The second patch (patch_2.txt) contains modifications to the module 
normal to take into account the new command:
  - register the command on startup
  - add relevant checks and actions in menu.c
It also patches the .rmk files to compile.

I will let you comment on this, and start working on implementing the 
'lock' command in the meanwhile. I hope I'll be able to send a first 
patch for the lock command by the end of the week.
