    Description

      Suggested by bar (see attached):

      1. Put m_specific and m_streaming into the union
      2. Add a dedicated function to calculate hashes for numeric values for the mysql5x hasher
      3. The separation between handler and data, see https://jira.mariadb.org/browse/MDEV-38394?focusedCommentId=321456&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-321456
