corruption on ADD PARTITION and LOCK TABLE
Bug#53770: Server crash at handler.cc:2076 on
LOAD DATA after timed out COALESCE PARTITION
5.5 fix for:
Bug#51042: REORGANIZE PARTITION can leave table in an
inconsistent state in case of crash
Needs to be back-ported to 5.1
5.5 fix for:
Bug#50418: DROP PARTITION does not interact with
transactions
Main problem was non-persistent operations done
before meta-data lock was taken (53770+53676).
And 53676 needed to keep the table/partitions opened and locked
while copying the data to the new partitions.
Also added thorough tests to spot some additional bugs
in the ddl_log code, which could result in bad state
between the .frm and partitions.
Collapsed patch, includes all fixes required from the reviewers.
As we check for the impossible partitions earlier, it's possible that we don't find any
suitable partitions at all. So this assertion just has to be corrected for this case.

value and NO_ZERO_DATE
The problem was that a older version of the error path for a
failed admin statement relied upon a few error conditions being
met in order to access a table handler, the first one being that
the table object pointer was not NULL. Probably due to chance,
in all cases a table object was closed but the reference wasn't
reset, the other conditions didn't evaluate to true. With the
addition of a new check on the error path, the handler started
being dereferenced whenever it was not reset to NULL, causing
problems for code paths which closed the table but didn't reset
the reference.
The solution is to reset the reference whenever a admin statement
fails and the tables are closed.

Reset reference to a closed table object, otherwise the error
path might attempt to access it.

The default storage engine is changed from MyISAM to
InnoDB, in all builds except for the embedded server.
In addition, the following system variables are
changed:
* innodb_file_per_table is enabled
* innodb_strict_mode is enabled
* innodb_file_format_name_update is changed
to 'Barracuda'
The test suite is changed so that tests that do not
explicitly include the have_innodb.inc are run with
--default-storage-engine=MyISAM. This is to ease the
transition, so that most regression tests are run
with the same engine as before.
Some tests are disabled for the embedded server
regression test, as the output of certain statements
will be different that for the regular server
(i.e SELECT @@default_storage_engine). This is to
ease transition.
mysql-test/mysql-test-run.pl:
The regression test suite now adds a
--default-storage-engine=MyISAM for all non-innodb
tests. This behaviour can be controlled by the
default-myisam switch in mysql-test-run
mysql-test/t/bootstrap-master.opt:
The bootstrap test can only be run without InnoDB
as it starts several mysqld instances on the same
datadir. This is possible with MyISAM, but not
with InnoDB.
storage/innobase/CMakeLists.txt:
Build InnoDB per default
storage/innobase/handler/ha_innodb.cc:
Change default values for system variables
Enable file_per_table
Enable strict_mode
Upgrade default file format to Barracuda

Problem was that partition pruning did not exclude the
last partition if the range was beyond it
(i.e. not using MAXVALUE)
Fix was to not include the last partition if the
partitioning function value was not within the partition
range.

REORGANIZE PARTITION
There were several problems which lead to this this,
all related to bad error handling.
1) There was several bugs preventing the ddl-log to be used for
cleaning up created files on error.
2) The error handling after the copy partition rows did not close
and unlock the tables, resulting in deletion of partitions
which were in use, which lead InnoDB to put the partition to
drop in a background queue.
sql/ha_partition.cc:
Bug#47343: InnoDB fails to clean-up after lock wait timeout on

Better error handling, if partition has been created/opened/locked
then make sure it is unlocked and closed before returning error.
The delete of the newly created partition is handled by the ddl-log.

as mentioned in the function header.

the name_len was not set correctly.
