Refs #25 - made sure signals that may be set to ignored in mysqld were set to default in the child process.

Going more MTR-friendly - for SST prefer to use mysql client, mysqldump and my_print_defaults from the local build tree.

refs #7 - merged fix from 5.5 branch. However, 5.6 branch has not (yet) surfaced similar applier hang as 5.5

Avoid creating innodb buffer pool dump/load thread if mysqld is started
with wsrep recovery mode (--wsrep-recover).

(Merged fix for lp:1305955 from lp:percona-xtradb-cluster)

THD's lex->definer initially holds "*current_user" for CURRENT_USER().
As a result when wsrep tries to create the trigger query, it incorrectly
uses "*current_user". Fixed by calling get_current_user() to get the
real current user.

Merged galera_create_trigger.test from github.com/codership/mysql-wsrep.

Restore fix for MDEV-4328 (revno: 3391) that got accidentally
overwritten while merging :
http://bazaar.launchpad.net/~codership/codership-mysql/5.5-23/revision/3900

Added a test case.

wsrep threads should be always be checked for existence & stopped on
server shutdown.

Analysis: after a red-black-tree lookup we use node withouth
checking did lookup succeed or not. This lead to situation
where NULL-pointer was used.

Fix: Add additional check that found node from red-back-tree
is valid.

Enable execution of CREATE TABLE SELECT in total order isolation. Added
a test case.

Contributed by : Andrew W Elble

OPTION_SKIP_REPLICATION flag needs to be preserved for events received
on non-originating nodes.

log-tc-size is 24K by default. Page size is 64K on PPC64. But log-tc-
size
must be at least 3 x page size. This is enforced by TC_LOG_MMAP::open()
with a comment: to guarantee non-empty pool.

This all makes server not startable in default configuration on PPC64.

Autosize log-tc-size, so that it's min value= page size * 3, default
value= page size * 6, block size= page size.

Annotate_rows event needs to be preserved until the last Rows event has
been applied because after it has been applied thd->query points to the
query stored inside this event.

Added an include file to check galera library version.

* Changed loopback detection to be done via ifa->ifa_flags
* Removed unused function wsrep_guess_address()

Add a testcase. The bug itself was fixed by the fix for MDEV-7316.

* Changed loopback detection to be done via ifa->ifa_flags
* Removed unused function wsrep_guess_address()

partially cherry-pick from mysql/5.6.
No test case (mysql/5.6 test case is useless, the correct
test case uses too much memory)

    Bug #49931          Incorrect type in read_log_event error
    Bug #49932          mysqlbinlog max_allowed_packet hard coded to 1GB

If somehow the COMMIT or XID event in an event group was missing, the code in
parallel replication to handle this was not sufficient, leading to server
deadlock.
