[gtk+/gtk-2-22] Parse lpoptions correctly

[Matthias Clasen <matthiasc src gnome org>]

commit 874ccc63a5751e076e77f2f8d2e53027b8301cee

    Parse lpoptions correctly
    
    Parse options job-sheets, job-hold-until and sides correctly.
    Add get_lpoption_name() for translation of lpoption names to
    gtk option names. Usable for options which values don't need
    conversion (e.g. number-up, number-up-layout, job-billing
    and job-priority).
    Rename array option_names to ppd_option_names to reflect its
    purpose better. Rename get_option_name() to get_ppd_option_name()
    because of the same reason.
