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)

BUG#1000269: Wrong result (extra rows) with semijoin+materialization, IN subqueries, join_cache_level>0
- make make_cond_after_sjm() correctly handle OR clauses where one branch refers to the semi-join table
  while the other branch refers to the non-semijoin table.

sql/slave.cc:
  add mutex protection, like in sql_parse.cc

The problem is that we can't check null_value field of non-basic constant without the item execution.:

The optimizer chose a less efficient execution plan due to the following
defects of the code:
1. the generic handler function handler::keyread_time did not take into account
   that in clustered primary keys record data is included into each index entry
2. the function make_join_readinfo erroneously decided that index only scan
   could not be used if join cache was empoyed.

Added no additional test case.
Adjusted some of the test results.

Changed HA_EXTRA_NORMAL to HA_EXTRA_NOT_USED (more clean)

mysql-test/suite/maria/lock.result:
  More extensive tests of LOCK TABLE with FLUSH and REPAIR
mysql-test/suite/maria/lock.test:
  More extensive tests of LOCK TABLE with FLUSH and REPAIR
sql/sql_admin.cc:
  Fix that REPAIR TABLE ... USE_FRM works with LOCK TABLES
sql/sql_base.cc:
  Ensure that transactions are closed in ARIA when doing flush
  HA_EXTRA_NORMAL -> HA_EXTRA_NOT_USED
  Don't call extra many times for a table in close_all_tables_for_name()
  Added test if table_list->table as this can happen in error situations
sql/sql_partition.cc:
  HA_EXTRA_NORMAL -> HA_EXTRA_NOT_USED
sql/sql_reload.cc:
  Fixed comment
sql/sql_table.cc:
  HA_EXTRA_NORMAL -> HA_EXTRA_NOT_USED
sql/sql_trigger.cc:
  HA_EXTRA_NORMAL -> HA_EXTRA_NOT_USED
sql/sql_truncate.cc:
  HA_EXTRA_FORCE_REOPEN -> HA_EXTRA_PREPARE_FOR_DROP for truncate, as this speeds up truncate by not having to flush the cache to disk.

mysql-test/suite/maria/maria-partitioning.result:
  New test case
mysql-test/suite/maria/maria-partitioning.test:
  New test case
sql/sql_base.cc:
  Ignore HA_EXTRA_NORMAL for wait_while_table_is_used()
  More DBUG
sql/sql_partition.cc:
  Don't use HA_EXTRA_FORCE_REOPEN for wait_while_table_is_used() as the table is opened multiple times (in prep_alter_part_table)
  This fixes the assert in Aria where we check if table is opened multiple times if HA_EXTRA_FORCE_REOPEN is issued

Fixed bug LP:973039 - Assertion `share->in_trans == 0' failed in maria_close on DROP TABLE under LOCK
- 5.5 was missing calls to ha_extra(HA_PREPARE_FOR_DROP | HA_PREPARE_FOR_RENAME);  Lost in merge 5.3 -> 5.5


sql/sql_admin.cc:
  Updated arguments for close_all_tables_for_name
sql/sql_base.h:
  Updated arguments for close_all_tables_for_name
sql/sql_partition.cc:
  Updated arguments for close_all_tables_for_name
sql/sql_table.cc:
  Updated arguments for close_all_tables_for_name
  Removed test of kill, as we have already called 'ha_extra(HA_PREPARE_FOR_DROP)' and the table may be inconsistent.
sql/sql_trigger.cc:
  Updated arguments for close_all_tables_for_name
sql/sql_truncate.cc:
  For truncate that is done with drop + recreate, signal that the table will be dropped.

This will contune the test case even if there was an error
and makes it easier to run a test that contains many sub tests against one engine.

(originally by Monty)

If we did nothing in resolving unique table conflict we should not retry (it leed to infinite loop).
Now we retry (recheck) unique table check only in case if we materialized a table.

- Let fix_semijoin_strategies_for_picked_join_order() set 
  POSITION::prefix_record_count for POSITION records that it copies from
  SJ_MATERIALIZATION_INFO::tables. 
  (These records do not have prefix_record_count set, because they are optimized
   as joins-inside-semijoin-nests, without full advance_sj_state() processing).  
 

  in greedy_search with LEFT JOINs and unique keys
- Backport the fix for BUG#806524 from MariaDB 5.3

The not_null_tables() of Item_func_not_all and Item_in_optimizer was inherited from
Item_func by mistake. It made the optimizer think that  subquery
predicates with ALL/ANY/IN were null-rejecting. This could trigger invalid
conversions of outer joins into inner joins.

It is problem of constant propagated to ref* access method (the problem was hiden by using debug binaries for testing).

The code to re-enable checkpointing after UNLOCK TABLES was lost in the 5.5
merge, so re-add it back in.

The failures are  missing entries in the slow query log.  The reason for the failure  are sleep() calls  with short duration 10ms, which is less than the default system timer resolution for various WaitForXXXObject functions  (15.6 ms) and thus can't work reliably.
The fix is to make sleeps tiny bit longer (20ms from 10ms) in the test.

let x = `SELECT <something>`

The fix is to detect the condition "no active connection",  to report error and die.
Note, that the check for no active connection was already in place for ordinary commands, 
and was missing only for assign-variable command.
