Background: Used encryption key_id is stored to encryption metadata
i.e. crypt_data that is stored on page 0 of the tablespace of the
table. crypt_data is created only if implicit encryption/not encryption
is requested i.e. ENCRYPTED=[YES|NO] table option is used
fil_create_new_single_table_tablespace on fil0fil.cc.
Later if encryption is enabled all tables that use default encryption
mode (i.e. no encryption table option is set) are encrypted with
default encryption key_id that is 1. See fil_crypt_start_encrypting_space on
fil0crypt.cc.
ha_innobase::check_table_options()
If default encryption is used and encryption is disabled, you may
not use nondefault encryption_key_id as it is not stored anywhere.

Problem affects INPLACE ALTER rename columns.
innobase_rename_column_try(): some strcmp() was replaced with my_strcasecmp(),
queries to update data dictionary was updated to not match column name case.
thd_rpl_stmt_based(): A new predicate to check if statement-based
replication is active. (This can also hold when replication is not
in use, but binlog is.)
que_thr_stop(), row_ins_duplicate_error_in_clust(),
row_ins_sec_index_entry_low(), row_ins(): On a duplicate key error,
only lock all index records when statement-based replication is in use.
ha_innobase::check_if_supported_inplace_alter(): Remove a redundant
condition and defer some computations.
If INNOBASE_ALTER_VERSIONED_REBUILD is set, innobase_need_rebuild()
will necessarily hold. Therefore, it is not necessary to assign
need_rebuild at the start of the function.
set both `password` and `authentication_string` columns in `mysql`.`user`
table for now.
Suppress the "password was ignored" warning if the password is
the same as the authentication string
* Fine-grained inplace skipping by INNOBASE_ALTER_VERSIONED_REBUILD;
* Fixed column WITHOUT SYSTEM VERSIONING + ADD COLUMN;
* Fixed instant field change (MDEV-16330);
* Revisited test versioning.online;
* Merged the test versioning.trx_id_versioning_attribute_persistence
to versioning.online;
* Renamed some versioning functions:
** change_fields_versioning_cache() -> vers_change_fields_cache()
** change_field_versioning_try() -> vers_change_field_try()
Skip condition moved out of func.

The parameters bool sync=true, bool read_only=false of mtr_t::start()
were added in
eca5b0fc17
(MySQL 5.7.3).
The parameter read_only was never used anywhere.
The parameter sync was only copied around, and would be returned
by the unused function mtr_t::is_async().
We do not need this dead code in MariaDB.

dictionary tables.

it will not fail due to the test instrumentation.

Fixed by adding table flag HA_WANTS_PRIMARY_KEY, which is like
HA_REQUIRE_PRIMARY_KEY but tells SQL upper layer that the storage engine
internally can handle tables without primary keys (for example for
sequences or trough user variables)

System libxml2 uses system zlib, it might conflicts with the bundled.
In particular, on centos5 old system zlib conflicts with the newer
(after c54271723c) bundled zlib which causes CONNECT to crash
on xml tests.
row_build_index_entry_low(): ext does not contain virtual columns.

Bug #27968952 INNODB CRASH/CORRUPTION WITH TEXT PREFIX INDEXES
Problem:
There are two problems:
1. If there is one secondary index on extenally
stored column and another seconday index on virtual column (whose
base column is not externally stored). then while updating seconday
index on vitrual column, virtual column data is replaced by
externally stoared column.
2. In row update operation, node->row contains
shallow copy of virtual data fields. While building an update vector
containing all the fields to be modified, compute virtual column.
which may causes change in virtual data fields in node->row.
In both the above cases, while updating seconday index on virtual
column, couldn't find the row and hit an explicite assert inside
ROW_NOT_FOUND.
Fix:
1. Added check if column is virtual then its ext flag should be ZERO
and virtual column data will not be replaced by offset column data.
2. Deep copy of virtual data fields for node->row.

Backport fix to mysql-5.7
Reviewed-by: Allen Lai <allen.lai@oracle.com>
No test case is added, because the MySQL 5.7 test case would pass
even when the fix is not present. We would need a test case that
only causes a locking conflict on the spatial index.
In RENAME TABLE, when an error occurs while renaming FOREIGN KEY
constraint, that error would be overwritten when renaming the
InnoDB internal tables related to FULLTEXT INDEX.
row_rename_table_for_mysql(): Do not attempt to rename the internal
tables if an error already occurred.
