Complete the merge of magne.mahre@oracle.com-20101102115354-vxcaxminmzglzalk
(WL#5185 Remove deprecated 5.1 features)

remove unused HA_READ_OUT_OF_SYNC

* use sql_mode_for_dates() where appropriate.
* always specify an argument for sql_mode_for_dates()
  (future-proof. easier to notice and fix if the caller
   will start using thd from a local variable or an argument)

remove unused HA_CAN_EXPORT
(with the merge of "FLUSH TABLE <table_list> FOR EXPORT",
this functionality should be added back, but differently -
no table flag, handler::extra() returns an error instead)

remove unused HA_BLOCK_CONST_TABLE

remove half-applied "Bug#14521864: MYSQL 5.1 TO 5.5 BUGS PARTITIONING"

fix simple_rename_or_index_change() to reuse alter_table_manage_keys()

it's not nice when unconfigured gtid prevents SHOW VARIABLES from working

remove TDC_RT_REMOVE_NOT_OWN_AND_MARK_NOT_USABLE

use get_table_def_key() instead of create_table_def_key() where appropriate

Fix bug MDEV-4885: When performance schema is disabled, autosized parameters show 18446744073709551615 instead of -1
(patch by Serg)

MDEV-4797 - Spider crash on show create table spider table and replication
            multi source to one of the partitions
MDEV-4747 - Spider: add missing install_spider.sql

Made sure that innodb tables for persistent statistics would not
considered by the server as system tables.

mysql-test/suite/rpl/t/rpl_err_ignoredtable.test:
  Wait until thread is killed.

            innodb_ft_user_stopword_table to DEFAULT

Setting plugin string variable with PLUGIN_VAR_MEMALLOC flag
to NULL causes server crash.

mysql-test/suite/sys_vars/r/innodb_ft_user_stopword_table_basic.result:
  Reset innodb_ft_user_stopword_table. Also tests MDEV-4801.
mysql-test/suite/sys_vars/t/innodb_ft_user_stopword_table_basic.test:
  Reset innodb_ft_user_stopword_table. Also tests MDEV-4801.
sql/sql_plugin.cc:
  When we got NULL value, do not strdup(NULL).

reverted the change done for WL 4443.

   Field_geom::store() should check if the source is it's value.

Fixed perfschema.relaylog failure.

mysql-test/suite/perfschema/r/relaylog.result:
  Failed file opens are not shown in P_S. Relevant revision:
  marc.alff@oracle.com-20120807154151-cwuazxu341rvrnmg

Temorary fix for a number of replication tests (rpl.rpl_temp_table_mix_row 
rpl.rpl_trunc_temp rpl.rpl_current_user rpl.rpl_gtid_master_promote):

- THD::decide_logging_format() should not assume that mysql.gtid_slave_pos is 
  a non-replicated table. This used to cause unintended behavior for COMMIT 
  statement: replication would switch to row-based, etc.

The question of what should be done when a user issues a statement that
explicitly modifies mysql.gtid_slave_pos table remains open.

Workaround for a possible GCC bug happening in my_fill_ucs2:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58039

Commenting out the optimized loop.
Using the original MySQL version.

Fixed main.plugin, main-test_sql_discovery.plugin failures.

storage/example/ha_example.cc:
  Issue a warning independently of DBUG status (needed for testing).

  mysys/ma_dyncol.c
  mysys/string.c
  sql/sql_string.cc
  sql/sql_string.h
  strings/ctype.c

Fixed main.partition_open_files_limit, innodb.innodb_bug12400341 failures.

These testcases use --max-connections=N command line option, which
was declared PARSE_EARLY during the merge. Embedded didn't handle
early options and failed to start due to unknown command line
option.

libmysqld/lib_sql.cc:
  Let embedded handle early options.
sql/mysqld.cc:
  Moved handling of early options to a separate function.
sql/mysqld.h:
  Moved handling of early options to a separate function.

Fixed funcs_1.is_statistics_mysql_embedded, funcs_1.is_columns_mysql_embedded,

Fixed main.partition_cache, main.partition_cache_innodb,
main.partition_cache_myisam, main.query_cache failures.

libmysqld/emb_qcache.cc:
  Restore proper method to retrieve warnings number.

Added forgotten partition_explicit_prune from mysql-5.6.

Backported the fix for
Bug#13559657: PARTITION SELECTION DOES NOT WORK WITH VIEWS
from mysql-5.6

There is a race condition during shutdown, that happens when "show status" runs during shutdown. 
Functions show_slave_running(), show_slave_received_heartbeats(), show_heartbeat_period() would dereference NULL pointer master_info_index, after this variable is  set to NULL in slave_end() during shutdown.
Fix introduces check for master_info_index == NULL in the affected functions.

Fixed "check of testcases" failure.

Value of INFORMATION_SCHEMA.PLUGINS.PLUGIN_TYPE_VERSION was
pointing to incorrect address and could change after server
restart.

storage/innobase/handler/i_s.cc:
  Use proper plugin info pointer (struct st_mysql_information_schema
  instead of ST_FIELD_INFO[]).

Fixed archive.archive non-debug failure.

Applied revision:
sergey.vojtovich@oracle.com-20111008171828-vje5pumzvl04rdbb

Archive didn't read blobs from original table while
performing REPAIR TABLE with non-debug builds.

storage/archive/ha_archive.cc:
  Mark all columns for read independently of DBUG state.
  It instructs ::get_row_version2() to read all blobs.
