5a86a61219 Fixed wrong error codes from InnoDB/XtraDB that caused %M to give system dependent error messages (for unknown error code)
- InnoDB now returns handler specific HA_WRONG_CREATE_OPTION instead of MySQL specific ER_ILLEGAL_HA_CREATE_OPTION
- This changes the user level error message from "Unknown error" to "Wrong create options"

a5731b27b7 MDEV-342: Do not mark old binlog file as cleanly closed during rotate until
the new file is fully synced to disk and binlog index. This fixes a window
where a crash would leave next server restart unable to detect that a crash
occured, causing recovery to fail.

e7362d457a MDEV-359: Fix another case where switch-off semisync could cause a race that ended with server crash.
This one was when the code releases and reaquires the lock with pthread_cond_wait() - and semisync is switched off meanwhile.

5e13093df1 MDEV-359: Server crash when SET GLOBAL rpl_semi_sync_master_enabled = OFF
The semisync code does a fast-but-unsafe check for enabled or not without lock,
followed by a slow-but-safe check under lock. However, if the slow check failed,
the code still referenced not valid data (in an assert() expression), causing a
crash.

Fixed by not running the incorrect assert when semisync is disabled.

0c69f22032 Fixed bug mdev-354.
Virtual columns of ENUM and SET data types were not supported properly
in the original patch that introduced virtual columns into MariaDB 5.2.
The problem was that for any  virtual column the patch used the 
interval_id field of the definition of the column in the frm file as
a reference to the virtual column expression.
The fix stores the optional interval_id of the virtual column in the
extended header of the virtual column expression.

d4d3ca204f Fixed lp:997460 Truncate table on partitioned Aria table fails with ER_ILLEGAL_HA
Fix is done by doing an autocommit in truncate table inside Aria

storage/maria/ha_maria.cc:
  Force a commit for TRUNCATE TABLE inside lock tables
  Check that we don't call TRUNCATE with concurrent inserts going on.
  Make ha_maria::implict_commit faster when we don't have Aria tables in the transaction.
  (Most of the patch is just re-indentation because I removed an if level)

da5214831d Fix for bug lp:944706, task MDEV-193
The patch enables back constant subquery execution during
query optimization after it was disabled during the development
of MWL#89 (cost-based choice of IN-TO-EXISTS vs MATERIALIZATION).

The main idea is that constant subqueries are allowed to be executed
during optimization if their execution is not expensive.

The approach is as follows:
- Constant subqueries are recursively optimized in the beginning of
  JOIN::optimize of the outer query. This is done by the new method
  JOIN::optimize_constant_subqueries(). This is done so that the cost
  of executing these queries can be estimated.
- Optimization of the outer query proceeds normally. During this phase
  the optimizer may request execution of non-expensive constant subqueries.
  Each place where the optimizer may potentially execute an expensive
  expression is guarded with the predicate Item::is_expensive().
- The implementation of Item_subselect::is_expensive has been extended
  to use the number of examined rows (estimated by the optimizer) as a
  way to determine whether the subquery is expensive or not.
- The new system variable "expensive_subquery_limit" controls how many
  examined rows are considered to be not expensive. The default is 100.

In addition, multiple changes were needed to make this solution work
in the light of the changes made by MWL#89. These changes were needed
to fix various crashes and wrong results, and legacy bugs discovered
during development.
