- Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,   and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)   For now, only in pkgs used in verification/hs94.1x64x5. - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:   since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad   is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
