refs codership/mysql-wsrep#53 - fencing LOAD DATA splitting related commit to not happen with ALTER processing

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.

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.
