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.

mysql-test/extra/rpl_tests/create_recursive_construct.inc:
  Changed the order of the calls in the procedure because the code
  that checks if a warning message is printed out expects that the
  first statement gives an warning what is not the case for INSERT
  INTO ta$CRC_ARG_level VALUES (47);
mysql-test/suite/binlog/r/binlog_stm_unsafe_warning.result:
  Updated the result file.
mysql-test/suite/binlog/r/binlog_unsafe.result:
  There are several changes here:
          
  (1) - Changed the CREATE PROCEDURE $CRC.
                                  
  (2) - The procedure $CRC was failing and the content of the binlog
        was being printed out, after fix (1) the failure disappeared.
                                  
  (3) - The warning message for unsafeness due to auto-increment collumns was
        changed.
                                  
  (4) - The warning message for unsafeness due to VERSION(), RAND() was changed.

sql/sql_class.cc:
  Moved the stmt_accessed_table_flag variable and related information to the
  LEX as we need the variable reset after each statement even inside a stored
  procedure, what did not happen if the information was in the THD.
          
  Changed the routine in the THD::binlog_query that prints the warning
  messages to avoid trying to print them when inside a stored procedure,
  function or trigger.
                          
  Checked for unsafeness when both performance and log tables where used.
  After the introduction of the performance schema, we need to check both.

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.

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

BUILD/compile-pentium-mysqlfs-debug:
  Remove build script for a feature that is long gone.

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.

******
This patch fixes the following bugs:
  - Bug#5889: Exit handler for a warning doesn't hide the warning in
    trigger
  - Bug#9857: Stored procedures: handler for sqlwarning ignored
  - Bug#23032: Handlers declared in a SP do not handle warnings generated
    in sub-SP
  - Bug#36185: Incorrect precedence for warning and exception handlers

The problem was in the way warnings/errors during stored routine execution
were handled. Prior to this patch the logic was as follows:

  - when a warning/an error happens: if we're executing a stored routine,
    and there is a handler for that warning/error, remember the handler,
    ignore the warning/error and continue execution.

  - after a stored routine instruction is executed: check for a remembered
    handler and activate one (if any).

This logic caused several problems:

  - if one instruction generates several warnings (errors) it's impossible
    to choose the right handler -- a handler for the first generated
    condition was chosen and remembered for activation.

  - mess with handling conditions in scopes different from the current one.

  - not putting generated warnings/errors into Warning Info (Diagnostic
    Area) is against The Standard.

The patch changes the logic as follows:

  - Diagnostic Area is cleared on the beginning of each statement that
    either is able to generate warnings, or is able to work with tables.

  - at the end of a stored routine instruction, Diagnostic Area is left
    intact.

  - Diagnostic Area is checked after each stored routine instruction. If
    an instruction generates several condition, it's now possible to take a
    look at all of them and determine an appropriate handler.

the precursor patch for Bug#52044.
When passing the TABLE instance for invalidation to the
query cache, we didn't always have a valid share
(in case of error).
Make sure we invalidate the table using TABLE_LIST, not
TABLE, object.

sql/sql_table.cc:
  Make sure we invalidate the table using TABLE_LIST, not
  TABLE, object.

Problem: The original patch didn't compile on debug_werror
due to wrong format in printf("%d") for size_t variables.

Fix: Adding cast to (int).

/*![:version:] Query Code */, where [:version:] is a sequence of 5 
digits representing the mysql server version(e.g /*!50200 ... */),
is a special comment that the query in it can be executed on those 
servers whose versions are larger than the version appearing in the 
comment. It leads to a security issue when slave's version is larger 
than master's. A malicious user can improve his privileges on slaves. 
Because slave SQL thread is running with SUPER privileges, so it can
execute queries that he/she does not have privileges on master.

This bug is fixed with the logic below: 
- To replace '!' with ' ' in the magic comments which are not applied on
  master. So they become common comments and will not be applied on slave.

- Example:
  'INSERT INTO t1 VALUES (1) /*!10000, (2)*/ /*!99999 ,(3)*/
  will be binlogged as
  'INSERT INTO t1 VALUES (1) /*!10000, (2)*/ /* 99999 ,(3)*/

            DELETE statement

Single-table delete ordered by a field that has a hash-type index
may cause an assertion failure or a crash.

An optimization added by the fix for the bug 36569 forced the
optimizer to use ORDER BY-compatible indices when applicable.

However, the existence of unsorted indices (HASH index algorithm
for some engines such as MEMORY/HEAP, NDB) was ignored.

The test_if_order_by_key function has been modified to skip
unsorted indices.

When opening tables for GRANT statement
to check that subject columns exist,
mysql_table_grant() would try to lock the
tables, and thus start a transaction.
This was unnecessary and lead to an assert.

  Use open_normal_and_derived_tables() rather than
  open_and_lock_tables() to avoid an assert
  that no transaction is started in GRANT statement.
