Reasons:
- as of 5.5.27, YEAR(2) is deprecated, hence the new warning;
- MDEV-553 - different error code/message on out-of-range autoincrement;
- INSERT IGNORE now produces a warning if a duplicate was encountered

from a MERGE view.
The problem was in the lost ability to be null for the table of a left join if it
is a view/derived table.
It hapenned because setup_table_map(), was called earlier then we merged
the view or derived.
Fixed by propagating new maybe_null flag during Item::update_used_tables().
Change in join_outer.test and join_outer_jcl6.test appeared because
IS NULL reported no used tables (i.e. constant) for argument which could not be
NULL and new maybe_null flag was propagated for IS NULL argument (Item_field)
because table the Item_field belonged to changed its maybe_null status.
The patch lifts the limitation of the current implementation
of ALTER TABLE that does not allow to build unique/primary
indexes by sort for MyISAM and Aria engines.
- Register counters directly in the array passed to maria_declare_plugin. As
a consequence, FLUSH TABLES will reset the counters.
- Update test results accordingly.
Analysis:
The following call stack shows that it is possible to set Item_cache::value_cached, and the relevant value
without setting Item_cache::example.
#0 Item_cache_temporal::store_packed at item.cc:8395
#1 get_datetime_value at item_cmpfunc.cc:915
#2 resolve_const_item at item.cc:7987
#3 propagate_cond_constants at sql_select.cc:12264
#4 propagate_cond_constants at sql_select.cc:12227
#5 optimize_cond at sql_select.cc:13026
#6 JOIN::optimize at sql_select.cc:1016
#7 st_select_lex::optimize_unflattened_subqueries at sql_lex.cc:3161
#8 JOIN::optimize_unflattened_subqueries at opt_subselect.cc:4880
#9 JOIN::optimize at sql_select.cc:1554
The fix is to set Item_cache_temporal::example even when the value is
set directly by Item_cache_temporal::store_packed. This makes the
Item_cache_temporal object consistent.
have_openssl variable was ON even when OpenSSL was not used (but YaSSL was).
fix that, so that have_openssl really corresponds to OpenSSL
rename not_openssl.inc to not_ssl.inc and fix the test accordingly.
With MDEV-532, the binlog_checkpoint event is logged asynchronously
from a binlog background thread. This causes some sporadic failures
in some test cases whose output depends on order of events in
binlog.
Fix using an include file that waits until the binlog checkpoint
event has been logged before proceeding with the test case.

Bug#11766342 INITIAL DB CREATION FAILS ON WINDOWS WITH AN ASSERT IN SQL_ERROR.CC
Improved bootstrap error handling:
- Detect and report file i/o errors
- Report query size errors with nearest query text
This was failing not only for P_S, but for any engine that had
HA_PRIMARY_KEY_REQUIRED_FOR_DELETE flag set (in the tree - only P_S and federated).
Because of this flag, read_set and write_set were (possibly) changed
on update. But later the code modified these bitmaps and restored them to the default
state, losing HA_PRIMARY_KEY_REQUIRED_FOR_DELETE related changes.

Bug #11766001: 59026: ALLOW MULTIPLE --PLUGIN-LOAD OPTIONS
Implemented support for a new command line option :
--plugin-load-add=<comma-separated-name-equals-value-list>
This option takes the same type of arguments that --plugin-load does
and complements --plugin-load (that continues to operate as before) by
appending its argument to the list specified by --plugin-load.
So --plugin-load can be considered a composite option consisting of
resetting the plugin load list and then calling --plugin-load-add to process
the argument.
Note that the order in which you specify --plugin-load and --plugin-load-add
is important : "--plugin-load=x --plugin-load-add=y" will be equivalent to
"--plugin-load=x,y" whereas "--plugin-load-add=y --plugin-load=x" will be
equivalent to "plugin-load=x".
Incompatible change : the --help --verbose command will no longer print the
--plugin-load variable's values (as it doesn't have one). Otherwise both --plugin-load
and --plugin-load-add are mentioned in it.
Make the commit checkpoint inside InnoDB be asynchroneous.

that introduced engine independent persistent statistics.
In particular:
- added an enumeration type for possible values of the system
variable use_stat_tables
- renamed KEY::real_rec_per_key to KEY::actual_rec_per_key
- optimized the collection of statistical data for any primary
key defined only on one column.
If a query referenced some system statistical tables, but not all of them,
then executing an ANALYZE command simultaneously with this query could
lead to a deadlock.
The fix prohibited reading statistics from system statistical tables
for such queries.
Removed the function unlock_tables_n_open_system_tables_for_write()
as not used anymore.
Performed some minor refactoring of the code in sql_statistics.cc.
Using too long table aliases in stored routines might
have caused server crashes.
Code in sp_head::merge_table_list() which is responsible
for collecting information about tables used in stored
routine was not aware of the fact that table alias might
have arbitrary length. I.e. it assumed that table alias
can't be longer than NAME_LEN bytes and allocated buffer
for a key identifying table accordingly.
This patch fixes the issue by ensuring that we use
dynamically allocated buffer for table key when table
alias is too long. By default stack based buffer is used
in which NAME_LEN bytes are reserved for table alias.

If a table was created for InnoDB then the execution of the

of the table.

When the primary key was dropped or changed statistics on secondary
indexes for the prefixes that included components of the primary
key was not removed from the table mysql.index_stats.
Also fixed: in the some cases when a column was changed statistics
on the indexes that included this column was not removed from the
table mysql.index_stats.
Also disabled the test mdev-504 for --ps-protocol.
