Fixing copyright text.

it couldn't parse the --ssl option.

This is a performance improvement fix.

Removed the "volatile" property of PFS_events_waits::m_wait_class.
Simplified the code accordingly.

The test for bug no 50939 was put in range.test which isn't such a good idea
since it requires partitioning. Fixed by moving the test case to
partitioning_range.test.

Updated the README file.

                        
After BUG#36649, warnings for sub-statements are cleared when a 
new sub-statement is started. This is problematic since it suppresses
warnings for unsafe statements in some cases. It is important that we
always give a warning to the client, because the user needs to know
when there is a risk that the slave goes out of sync.
                        
We fixed the problem by generating warning messages for unsafe statements
while returning from a stored procedure, function, trigger or while
executing a top level statement.
                        
We also started checking unsafeness when both performance and log tables are
used. This is necessary after the performance schema which does a distinction
between performance and log tables.

Fix by adding "DEPENDS gen_lex_hash" to ADD_CUSTOM_COMMAND(),
so it regenerates lex_hash.h whenever gen_lex_lash changes.

Also, make sql dependent on GenServerSource to avoid concurrent 
generation of lex_hash.h (once for sql , and in parallel for embedded)

Post-merge fix: add missing comma.

           INSERT IGNORE ... SELECT ... UNION SELECT ...

This assert was triggered by INSERT IGNORE ... SELECT. The assert checks that a
statement either sends OK or an error to the client. If the bug was triggered
on release builds, it caused OK to be sent to the client instead of the correct
error message (in this case ER_FIELD_SPECIFIED_TWICE).

The reason the assert was triggered, was that lex->no_error was set to TRUE
during JOIN::optimize() because of IGNORE. This causes all errors to be ignored.
However, not all errors can be ignored. Some, such as ER_FIELD_SPECIFIED_TWICE
will cause the INSERT to fail no matter what. But since lex->no_error was set,
the critical errors were ignored, the INSERT failed and neither OK nor the
error message was sent to the client.

This patch fixes the problem by temporarily turning off lex->no_error in
places where errors cannot be ignored during processing of INSERT ... SELECT.

Test case added to insert.test.

Post-merge fix: remove --with-debug=full, it was only used for safemalloc.

read_rnd_buffer_size

Applied the updated description from Paul's patch.

Undo workaround as fix is being merged in

Restore the original behavior of check-cpu with respect to core2.
It isn't used as a actual target processor type, but as a mean to
perform other kinds of architecture checks.

- Simplify sql-bench installation, 
do not try to resolve names : this leads to probem
if builddir is symlink located on different filesystem.
(reported by alik)

- Make WITHOUT_XXX (disabling plugin) work for DEFAULT
plugins. Prior to the patch is behaved just like 
MANDATORY.

- LINK_LIBRARIES in MYSQL_ADD_PLUGIN had no effect for
statically linked plugins.

- Fix constant rebuild of initdb target on Windows.

file .\item_subselect.cc, line 836

IN quantified predicates are never executed directly. They are rather wrapped
inside nodes called IN Optimizers (Item_in_optimizer) which take care of the
execution. However, this is not done during query preparation. Unfortunately
the LIKE predicate pre-evaluates constant right-hand side arguments even
during name resolution. Likely this is meant as an optimization.

Fixed by not pre-evaluating LIKE arguments in view prepare mode.

Reverted the ulong->uint diff
Re-applied the first diff.
The original commit message follows:

enum plugin system variables are ulong internally, not int.
On systems where long is not the same as an int it causes
problems. 
Fixed by correct typecasting. Removed the test from the 
experimental list.
