      Bug#13793813 Removing 3 debug lines from signal handler because there can be race conditions during shutdown (DBUG data structures have been destroyed)

      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.

No bundle (reason: useless for push emails).
