The second line of changes related to replacing xtrabackup with mariabackup: 1) All unnecessary references to xtrabackup are removed from the documentation, from some comments, from the control files that are used to prepare the packages. 2) Made corrections of the tests from the galera_3nodes suite that mentioned xtrabackup or the old (associated with xtrabackup) version of innobackupex. 3) Fixed flaws in the galera_3nodes mtr suite control scripts, because of which they could not work with mariabackup. 4) Fixed numerous bugs in the SST scripts and in the mtr test files (galera_3nodes mtr suite) that prevented the use of Galera with IPv6 addresses. 5) Fixed flaws in tests for rsync and mysqldump (for galera_3nodes mtr tests suite). These tests were not performed successfully without these fixes. https://jira.mariadb.org/browse/MDEV-17835
