mysqldump --skip-events --all-databases dumped data of the mysqld.event table,
and during the restoration from this dump events were created in spite
of the --skip-events option.

The mysqldump client has been modified to ignore mysql.event table data
in case of --skip-events options.

  Fixed bug #29938.
  The dump_table function has been modified to skip dumping of

  client option.

DELETE FROM ... USING ... statements with the following type of 
ambiguous aliasing gave unexpected results:
DELETE FROM t1 AS alias USING t1, t2 AS alias WHERE t1.a = alias.a;
This query would leave table t1 intact but delete rows from t2.
Fixed by changing DELETE FROM ... USING syntax so that only alias 
references (as opposed to alias declarations) may be used in FROM.

When dumping database from a 4.x server, the mysqldump client
inserted a delimiter sign inside special commentaries of the form:
  /*!... CREATE DATABASE IF NOT EXISTS ... ;*/
During restoration that dump file was splitten by delimiter signs on
the client side, and the rest of some commentary strings was prepended
to following statements.

The 4x_server_emul test case option has been added for use with the
DBUG_EXECUTE_IF debugging macro. This option affects debug server
builds only to emulate particular behavior of a 4.x server for
the mysqldump client testing. Non-debugging builds are not affected.

sql/sql_parse.cc:
  Fixed bug #30126.
  The mysqldump client uses the "SHOW CREATE DATABASE" query to
  obtain the "CREATE DATABASE" statement from that database.
  The 4.x server doesn't recognise that query, and mysqldump
  forms the "CREATE DATABASE" statement from scratch.
  That statement was formed incorrectly.
  
  To enforce the mysqldump client to create that statement from
  scratch, debugging code has been added to the mysql_execute_command
  function: in tcase of the --loose-debug=d,4x_server_emul option,
  the server returns parse error to client to emulate old behaviour.
  
  The 4x_server_emul test case option has been added for use with the
  DBUG_EXECUTE_IF debugging macro. This option affects debug server
  builds only to emulate particular behavior of a 4.x server for
  the mysqldump client testing. Non-debugging builds are not affected.
client/mysqldump.c:

  The init_dumping_tables function has been modified to output semicolon
  outside of commentaries.

The fix for WL3527 adds tests that test if the index usage hints
combinations don't cause syntax errors.
The EXPLAIN for one of these tests can be affected by the size of the
rowid on the disk (affected by the presence of large file support). 
Fixed to avoid the platform dependent test result by removing the 
irrelevant columns from the EXPLAIN result.

The optimization that uses a unique index to remove GROUP BY did not 
ensure that the index was actually used, thus violating the ORDER BY
that is implied by GROUP BY.
Fixed by replacing GROUP BY with ORDER BY if the GROUP BY clause contains
a unique index over non-nullable field(s). In case GROUP BY ... ORDER BY 
null is used, GROUP BY is simply removed.

mysql-test/r/distinct.result:
  Bug#30596: Changed test case. 
  Prior to Bug#16458, These queries use temp table and filesort. The
  bug was that they used a temp table. However, that patch removed
  filesort also, in which case we can no longer gurantee correct ordering.
mysql-test/r/group_by.result:
  Bug#30596: Correct result
  The test case for IGNORE INDEX FOR GROUP BY gets degraded performance 
  (unneccesary filesort). This is due to Bug#30665, which will be fixed separately.

Currently the Last_query_cost session status variable shows
only the cost of a single flat subselect. For complex queries
(with subselects or unions etc) Last_query_cost is not valid
as it was showing the cost for the last optimized subselect.
Fixed by reseting to zero Last_query_cost when the complete
cost of the query cannot be determined.
Last_query_cost will be non-zero only for single flat queries.
