In summary, wsrep_node_address and wsrep_sst_receive_address can now
be set to IPv6 addresses escaped by []. Rsync SST works out ouf the
box thanks to rsync daemon listening on both IPv4 and IPv6 sockets by
default. For xtrabackup SST onver IPv6 one needs to set sockopt in
the [sst] section of joiner's configuration file to ",pf=ip6" if
using socat as a streamer or to "-6" if using netcat.
1. Passes wsrep_sst_auth_value to SST scripts via WSREP_SST_OPT_AUTH envronmental variable, so it never appears on the command line
2. In mysqldump and xtrabackup* SST scripts which rely on MySQL authentication, instead of passing password on the command line, SST script sets MYSQL_PWD environment variable, so that password also never appears on the mysqldump/innobackupex command line.

* improves MySQL client version check making it no less than required as opposed to exactly as required.
* adds event table copying to ensure same results as with rsync SST.
Removed 'galera-sst-mode' option from mysqldump and added logic
in wsrep_sst_mysqldump script to retrieve gtid_binlog_state from
donor node and send it to the joiner node.
* Merged patches pushed to 10.0.
* Additional fix in wsrep_sst_mysqldump.sh to control use
of RESET MASTER and mysqldump's galera-sst-mode option based
on joiner's @@log-bin value.
state to the joiner
In mysqldump SST, if Galera nodes are started with --log-bin and
-log-slave-updates, the GTID sequence increases as the dump is
played on the joiner, leaving behind the donor.
This patch introduces a new mysqldump option --galera-sst-mode,
which if enabled, would
a) Add command to set off binary logging (log_bin=OFF).
b) Add command to set @@global.gtid_binlog_state to that
of donor.
This will help in keeping the GTIDs consistent post-SST across
the nodes.
* Removed the unnecessary call to wsrep_cleanup_progress_file,
which was returning code 1 and eventually causing SST to fail.
* Also initialized the unused WSREP_SST_OPT_CONF to avoid error
message.
