      The my_default_lc_messages variable was not exported by mysqld causing
      link error(undefined symbol) when compiling ha_archive as dynamic plugin on Windows.
      
      Change the my_default_lc_messags variable to be exported by mysqld using
      the MYSQL_PLUGIN_IMPORT macro.

      This fixes an issue noticed in the Valgrind tests after purge was removed from
      the master thread. When purge is run in a separate thread it calls trx_purge()
      more often and that leads to more truncate calls. This fix reduces the number
      of truncate calls by eliminating a test where we truncate also when there is
      nothing to purge.
