mysql.column_stat, mysql.table_stat for the type DECIMAL(12,4).
When cached the values from these columns are multiplied by factor 10^5
and stored as ulong numbers now. 

Renamed the system variable optimizer_use_stat_tables to use_stat_tables.
This variable now has only 3 possible values:
'never', 'complementary', 'preferably'.
If the server has been launched with
--use-stat-tables='complementary'|'preferably'
then the statictics tables can be employed by the optimizer and by the
ANALYZE command. 

that analyzes only some columns from a table.

that analyzes only some columns from a table.

Otherwise yum on fedora will not install them
(rpm will, yum on centos and rhel will).

Build MariaDB-compat rpm by repackaging files from MariaDB-shared-5.3.*.rpm
Or RHEL6/CentOS6 make all other MariaDB rpms depend on MariaDB-compat.

but restart it on upgrade, if it was already running

use my.cnf includes to split one big my.cnf file in server and client parts.

remove "Provides: mysql-libs" (doesn't help on CentOS 6)

configure with cmake -DRPM=distro

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)

the column cardinality of the table information_schema.statistics.

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.

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.
