This makes PBXT implement the commit_ordered() method, so that cross-engine
START TRANSACTION WITH CONSISTENT SNAPSHOT works actually consistent with
XtraDB.
Also mark the version number to show this is the -rpl feature preview.

Omit the directory part to make the output the same as SHOW MASTER STATUS.

Also fix one incorrect printf() format.

 - MWL#47, allowing to annotate row-based binlog events with the SQL test of
   the originating query (eg. in mysqlbinlog output).

 - row_based_replication_without_primary_key.patch, providing more intelligent
   selection of index to use on slave when applying row-based binlog events
   for tables with no primary key.

 - Make mysqlbinlog omit redundant `use` around BEGIN/SAVEPOINT/COMMIT/
   ROLLBACK in 5.0 binlogs.

This is a merge of percona patch mysqlbinlog_fix.patch.

Apparently, MySQL 5.0 does not flag BEGIN/SAVEPOINT/COMMIT/ROLLBACK statements
in its binlogs with LOG_EVENT_SUPPRESS_USE_F like 5.1+ does. This causes
unnecessary `use` statements around such statements when the binlog is dumped
by mysqlbinlog.

Fix by always suppressing the output of `use` for these statements.

This patch adds options to annotate the binlog (and the mysqlbinlog
output) with the original SQL query for queries that are logged
using row-based replication.

This patch improves the selection of index to use to apply row-based
DELETE and UPDATE events on tables with no primary key (original code
picks the first index unconditionally).
If ANALYZE TABLE is done, the index cardinalities will be compared and
the best index will be used.

Fixes some problems in the original patch:

 - Without ANALYZE TABLE, rec_per_key statistics is not available; in this
   case the original patch could choose a really bad index, even ignoring
   a primary key.

 - The original patch did not consider multi-column keys correctly, and
   could thus pick a less desirable single-column key over a good
   multi-column index.

Also fixes Bug#58997, and adds test cases.

don't fill in handlerton::commit member, as it's not used
and makes MySQL believe that Aria is transactional.
Fix the TRANSACTIONAL=1 warning.

set thd->password appropriately also for cases when a user was not found.

It was missing from EXTRA_DIST in Makefile.am.

(Includes patch for overrun detected by valgrind thanks to previous my_alloca() -> my_malloc() patch)

mysys/thr_lock.c:
  Fixed typo that caused compile failure

- This allows us to detect missing my_afree() calls and also find overruns (when running with valgrind) to alloca() areas.
- Added missing my_afree() calls
- Fixed wrong call to my_afree()


include/my_sys.h:
  When compiling with valgrind, change my_alloca() to use my_malloc()
mysql-test/suite/innodb/t/innodb_bug57255.test:

  Add missing my_afree() calls.
storage/maria/ma_rt_split.c:
  Fixed wrong parameter to my_afree()

storage/maria/ma_check.c:
  Allocate also memory for nodflag and transid's
storage/maria/ma_write.c:
  Allow nodflag and transid as part of key.
  (This has nothing to do with the bug report, but it's a safer check).
storage/maria/maria_def.h:
  Define MARIA_MAX_POINTER_LENGTH (length of pointer to node)
  Added node pointer length to MARIA_INDEX_OVERHEAD_SIZE, as this is part of the key.
  (Safety fix)

Made archive.test a bit more safe



mysql-test/r/archive.result:
  Added removal of files to make rerun of failed test work

  Added removal of files to make rerun of failed test work

  Better warning message if lock test fails

MBug#687320: Fix sporadic test failures in innodb_mysql.test and partition_innodb_semi_consistent.test

Problem is that these tests run with --innodb-lock-wait-timeout=2 in .opt
(and this is necessary as built-in innodb does not allow to change this
dynamically). This cases another part of the test to occasionally time
out an UPDATE, which subsequently caused the test case to timeout due to
waiting for a condition (successful UPDATE) that never occurs.

Fixed by re-trying the update in case of timeout.

Tested by inserting a sleep() in the connection that the UPDATE is waiting
for, and checking that the retry loops a couple of times until the other
connection is done and COMMITs.

the same execution plan that is in the output of the corresponding
EXPLAIN.

Problem : mtr reports test failure because it sees
[ERROR] mysqld got exception 0x80000003 ;
in the .err file

The exception comes from DBUG_EXECUTE_IF (.. abort())

Fix:  use DBUG_ABORT instead of abort() - it does not throw 
any exceptions.

The reason for failure is that DBUG_EXECUTE_IF in mi_open()
only worked for Unix-formatted file names, due to strstr(name, "/crashed")

The fix change strstr() above to strstr(name, "crashed"), to it can work with 
Windows file names as well.
