Add a new error message when table is encrypted but decryption
fails. Use this new error message on InnoDB/XtraDB.

type_spatial_indexes test is now be re-enabled, and the new result file
can be used for creating engine-specific rdiffs

ALTER TABLE should either bypass enforce-storage-engine, or mysql_upgrade
should refuse to run

Allow user to alter contents of existing table without enforcing
storage engine. However, enforce storage engine on ALTER TABLE
x ENGINE=y;

Adjust the test case to try and avoid some sporadic failures on loaded test
hosts.

The wait for SQL thread to stop may complete before worker threads
have completed.

The problem was fixed earlier by one of the MDEV-8728 subtasks.
Adding a test case only.

Disable IDENTITY_SUBST propagation for ZEROFILL columns,
as discussed with Sergei.

The code was using the wrong variable when comparing the binlog name
for the UNTIL position. This could cause the comparison to fail after
binlog rotation, in turn causing the UNTIL clause to not trigger slave
stop.

MDEV-8755 Equal field propagation is not performed any longer for the IN list when multiple comparison types

MDEV-8712 Wrong result for SELECT..WHERE latin1_bin_column=_latin1'a' AND latin1_bin_column='A'

MDEV-8754 Wrong result for SELECT..WHERE year_field=2020 AND NULLIF(year_field,2010)='2020'
Problems:
1. Item_func_nullif stored a copy of args[0] in a private member m_args0_copy,
   which was invisible for the inherited Item_func menthods, like
   update_used_tables(). As a result, after equal field propagation
   things like Item_func_nullif::const_item() could return wrong result
   and a non-constant NULLIF() was erroneously treated as a constant
   at optimize_cond() time.
   Solution: removing m_args0_copy and storing the return value item
   in args[2] instead.
2. Equal field propagation did not work well for Item_fun_nullif.
   Solution: using ANY_SUBST for args[0] and args[1], as they are in
   comparison, and IDENTITY_SUBST for args[2], as it's not in comparison.

MDEV-8785 Wrong results for EXPLAIN EXTENDED...WHERE NULLIF(latin1_col, _utf8'a' COLLATE utf8_bin) IS NOT NULL

create a "preset" file to enable all encryption options at once

--encrypt-binlog and --encrypt-tmp-files used to mean
"encrypt XXX if encryption is available, otherwise don't encrypt",
now they mean "encrypt or fail with an error".

MDEV-8706 Wrong result for SELECT..WHERE time_column=TIMESTAMP'2015-08-30 00:00:00' AND time_column='00:00:00'

MDEV-8741 Equal field propagation leaves some remainders after simplifying WH ERE zerofill_column=2010 AND zerofill_column>=2010

(MDEV-8617: Post-fix for 10.1)
* Reset THD's PS members before returning when node is
not ready
* Add CF_SKIP_WSREP_CHECK flag to COM_STMT_XXX commands
* Skip TO replication of COM_STMT_PREPAREs for MyISAM
* Updated tests

Problem was -O2 and __attribute__((nonnull)) when it should have been
__attribute__((nonnull(1,2,3,4,5)))

Fixed unsafe reference to null pointer.

MDEV-8766 Wrong result for SELECT..WHERE LENGTH(time_column)=8 AND time_column=TIMESTAMP'2001-01-01 10:20:31'

remove old "to-be-implemented" definition of
the default-tmp-storage-engine option.

Added encryption support for online alter table where InnoDB temporary
files are used. Added similar support also for tables containing
full text-indexes.

Made sure that table remains encrypted during discard and import
tablespace.

MDEV-8699 Wrong result for SELECT..WHERE HEX(date_column)!='323030312D30312D3031' AND date_column='2001-01-01x'

The fix for MDEV-8749 also fixed MDEV-8742.
Just adding the test case from the bug report.

MDEV-8703 Wrong result for SELECT..WHERE LENGTH(decimal_10_1_column)!=3 AND decimal_10_1_column=1.10

Moving to field.cc.

Follow-up for MDEV-6066: new default value, the result file needs to be updated

Suppress errors about not being able to load plugins from file_key_management library.
Errors about the non-existing library are already suppressed globally.

New defaults for query cache caused wrong test output
