Put the definition of `FEATURES_USED` in common and use the variable instead of duplicating code. This required defining 'FEATURES_OPTIONAL_ONLY|USED' to not overwrite the value of 'FEATURES_OPTIONAL' as was done before. Also add 'FEATURES_OPTIONAL_MISSING' to list optional features that were not included as not provided. This removes the need to print FEATURES_MISSING with the optional features too.
