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.

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.

 The functions ROW_COUNT/FOUND_ROWS are indeed not safe to be used in 
 statement based replication.
 Added code to declare them as such and switch the statement they're in
 to row based logging for mixed mode.

    and strategy (explain)
  
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.

for bug 30377: use the function instead of
the complex condition.

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.

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.

1) Ensure "init_db.sql" and "test_db-sql" really get built.

2) Ensure the "*.def" files with NetWare linker options get distributed to the proper directories.

When locking a "fast" mutex a static variable cpu_count 
was used as a flag to initialize itself on the first usage 
by calling sysconf() and setting non-zero value.
This is not thread and optimization safe on some 
platforms. That's why the global initialization needs 
to be done once in a designated function.
This will also speed up the usage (by a small bit) 
because it won't have to check if it's initialized on
every call.

Fixed by moving the fast mutexes initialization out of 
my_pthread_fastmutex_lock() to fastmutex_global_init()
and call it from my_init()
