GRUB2: *BSD and more patch

[Sergey Matveychuk <sem@ciam.ru>]

[-- Attachment #1: Type: text/plain, Size: 351 bytes --]

Here is a patch with *BSD stuff.

Also I've moved pupa_util_biosdisk_init() above pupa_guess_root_device() 
in util/pupa-emu.c because of pupa_guess_root_device() use parsed 
device.map but reading and parsing do in pupa_util_biosdisk_init().

I've tested the patch buth FreeBSD 4.x and 5.x. It should be tested on 
NetBSD and OpenBSD also.
