    org-latex-default-packages-alist: Refine packages for font management
    
    * lisp/org.el (org-latex-default-packages-alist): Change to refine
    font management depending on the latex compiler.
    
    Differentiate between pdflatex and lualatex/xetex
    packages for font management.  lualatex/xetex should use
    fontspec instead of fontenc/inputenc.  When using
    fontspec, you need to load amsmath before fontspec
    and you don't need amssymb.
