Subject: Numerous changes to support building classic installer ISOs:

 - rename {media}{source} to {media}{label} and require the user to supply it
   o  automatically add the LABEL= prefix, rather than removing it
 - rename {settings}{name} to {settings}{distro}
 - move get_system_root() to ISOBuild - CI builds use it as the urpmi-root
 - add new requirements in Config::check_config()
 - rename build_live_iso() to build_iso() and support CI builds
   o make output to file non-optional - we always want a file
   o add the DATE.txt file to the ISO image
 - modify prepare_iso_bootloader to support CI boot menus
