bug#27007: boot-parameters are not documented

It seems fine ! So to summarize, <menu-entry> would be moved to (gnu
bootloader). A procedure menu-entry->boot-parameters would assure
the mapping in (gnu bootloader).

Each booloader in (gnu bootloader xxx), would add
bootloader-configuration-menu-entries to generated entries.

I'll be afk for a week, but I'll submit a patch and the updated
documentation for this point when coming back.

Thanks for your fast answers :)
