[tex-live] lambda, omega, latex.ini

Whatever will be decided now or later about hiding pdftex related
primitives, I suggest to use the following skeleton for the formats that
default to dvi mode:

    \ifx\pdfoutput\undefined
    \else
      \ifx\pdfoutput\relax
      \else
         % here goes the pdftex related code, e.g.
         % disable primitives, load defaults...
         ...
      \fi
    \fi

    % here goes the usual format initialization, e.g.
    \scrollmode
    \input latex.ltx

    \endinput

That way, people can switch to a different engine if they want.

Speaking for myself (and only for myself) I would do it differently,
but I can live with the suggestion (plus my improvements).
