Displaying the correct build date in feeds is as important today as it was twelve years ago when this ticket was opened. Fix an issue where all feeds in WordPress showed the same date for their last build date (the datapoint is `lastBuildDate`, `updated` or `dc:date` depending on the feed type). Introduce a new `get_last_build_date` filter to adjust the date used for `lastBuildDate`. Developers who previously filtered `get_lastcommentmodified` to alter feed dates should use this filter instead. * `get_last_build_date` extracts the latest post (or comment) in the current WP_Query object. * In all feed templates, use `get_last_build_date` vs `get_lastpostmodified( 'GMT' );`. Props stevenkword, spacedmonkey, ryanshoover, mauteri, nacin, jorbin, MikeNGarrett, Denis-de-Bernardy, peaceablewhale. Fixes #4575.
