Remove the UAT macro usage. The UAT API is nifty for dissectors but clunky for everything else. This allows using a hash table to store macros, that is the natural data structure for the use case (and faster). It also allows using the existing filter GUI dialog, adapted for display filter macros. The difference isn't huge but it's better and less limited than the more generic UAT dialog, with room for improvement. Changing the UAT dialog for filter specific use cases is difficult. The config file is renamed to "dmacros" and uses the same format as "dfilter", that is more amenable and forgiving for hand-editing than the UAT storage format. There is some logic to convert the "dfilter_macros" UAT config file to a "dmacros" filter config file, for backward-compatibility. The conversion is only done if there is no existing "dmacros" file in the profile folder.
