Test galera_sst_mysqldump often fails with error "2013: Lost connection to MySQL server during query". The connection is lost after the test restart one of the nodes. This happens because the server closes client connections if it is joining a cluster through SST method mysqldump. On unlucky runs of the test it is possible that mysqld is restarted, and then mtr client is disconnected while it tries to determine if galera is ready before going on with the test. This patch rewrites galera_wait_ready.inc so that it is immune to being disconnected.
