[DATABASE] Some query improvements
Make common_sql_weight employ standard SQL functions for the timestamp difference in seconds. Also replace UTC_TIMESTAMP in the MariaDB-specific part with CURRENT_TIMESTAMP as it is the only occurence and GNU social sets UTC as a default timezone. In a delete_orphan_files.php script simplify the main query considerably. In clean_profiles.php stop using COUNT as if it is ANY, that is unnecessary punishment for the database. Instead implement the anti-join with a left outer join. In Autocomplete and Activitypub_profile use joins instead of a WHERE OR anti-pattern for the semi-joins. In lib/ui/galleryaction.php replace a CROSS JOIN with an INNER JOIN. In actions/sup.php remove a redundant subquery: WHERE is applied before grouping either way.
