TDC_RT_REMOVE_NOT_OWN_KEEP_SHARE is not same as
TDC_RT_REMOVE_NOT_OWN_AND_MARK_NOT_USABLE. Comment in sql_table.cc says:

      Storage engine has requested exclusive lock only for prepare phase
      and we are not under LOCK TABLES.
      Don't mark TABLE_SHARE as old in this case, as this won't allow opening
      of table by other threads during main phase of in-place ALTER TABLE.

At this moment we hold exclusive metadata lock, all we should do
is purge unused TABLE objects.

sql/sql_base.cc:
  Restore 5.6 behavior of TDC_RT_REMOVE_NOT_OWN_KEEP_SHARE.
sql/sql_base.h:
  Restore 5.6 behavior of TDC_RT_REMOVE_NOT_OWN_KEEP_SHARE.

  other classes.

  Use different way to retrieve refman link.
mysql-test/suite/innodb/t/help_url.test:
  Accessing discarded tablespace doesn't cause loud error message anymore.
  Use different way to retrieve refman link.

Fixed connect compilation failure (with ODBC).

storage/connect/odbconn.cpp:
  min/max are not defined by my_global.h anymore, include osutil.h instead.

- Make THD::raise_condition() call push_warning() after set_error_status() call.
  (they seem to have accidentally exchanged in this merge cset:
   sergii@pisem.net-20130721143919-7cltcw2l9g29f983)
- Rollback the patch from two csets before (the one with comment:
   Update filesort_debug.test (see comment #1 in MDEV-4786 for analysis))

- As of 10.0.2, MariaDB has mysql.gtid_slave_pos table as system table.

* update results
* don't force HA_CREATE_DELAY_KEY_WRITE on all temp tables,
  (bad for CREATE ... LIKE) instead imply it in myisam/aria
* restore HA_ERR_TABLE_DEF_CHANGED in archive
* increase the default number of rwlock classes in P_S to fit all our rwlocks

includes:
* remove some remnants of "Bug#14521864: MYSQL 5.1 TO 5.5 BUGS PARTITIONING"
* introduce LOCK_share, now LOCK_ha_data is strictly for engines
* rea_create_table() always creates .par file (even in "frm-only" mode)
* fix a 5.6 bug, temp file leak on dummy ALTER TABLE

test suite added to be sure that bug is fixed

MDEV-4647: Valgrind warnings (Conditional jump or move depends on uninitialised value) in Item_equal::fix_fields
Fix to calm down valgrind.

(fix of http://bugs.mysql.com/bug.php?id=69623)

  
In the case of loose scan used as input for order by, end_send()
didn't detect correctly that a loose scan was used, and didn't copy
the non-aggregated fields from the temp table used for ORDER BY.
  
The fix uses the fact that the quick select used for sorting is
attached to JOIN::pre_sort_join_tab instead of JOIN::join_tab.

MDEV-4570 [PATCH] Sys_query_cache_limit initialization depends on initialization in other source files

 REFRESH_FAST do not fit in 32 bit

MDEV-4782: Valgrind warnings (Conditional jump or move depends on uninitialised value) with InnoDB, semijoin
- in sub_select(): don't call table->file->position() when reading the first record
  produced an error.

pfs unit test fixed.

Backport the fix olav.sandstaa@sun.com-20101102184747-qfuntqwj021imy9r:
"Fix for Bug#52660 Perf. regr. using ICP for MyISAM on range queries on an index containing TEXT" 
(together with further fixes in that code) into MyISAM and Aria.

mdev-4173: Wrong result (extra row) with semijoin=on, joins in outer query, LEFT JOIN in the subquery
Apply the patch from Patryk Pomykalski:
- create_internal_tmp_table_from_heap() will now return information whether
  the last row that we tried to write was a duplicate row.
(mysql-5.6 also has this change)
