mysql-test/extra/rpl_tests/rpl_row_basic.test:
  remove extra sync_slave_with_master

The problem was because the event allocated in mysql_client_binlog_statement
was not freed when an error occured while applying the event.

sql/sql_binlog.cc:
  Delete the event if apply it failed

pb notices differences in results at the very beginning of the test.

Absense of mysql.ndb_apply_status must be benign anyway, but the warning should not happen
if have_ndb.inc is invoked ahead of ndb_master-slave.
Fixed with relocation of the macros.


mysql-test/suite/rpl_ndb/t/rpl_ndb_mixed_engines_transactions.test:
  positioning have_ndb prior ndb_master-slave

BUG#38369, enable rpl_row_basic_7ndb test

Post-merge fix: mysql_client_test.c is compiled by C compilers
and some C compilers don't support mixed declarations and code
and it's explicitly forbidden by ISO C90.

tests/mysql_client_test.c:
  Don't mix declarations and code.

Note: NULL merge of sql/sql_yacc.yy, the fix for bug#38296 will be provided separately for 5.1

Fixed missing DBUG_RETURN in the function find_key_block

This fix is for 5.0 only : back porting the 6.0 patch manually

The parser code in sql/sql_yacc.yy needs to be more robust to out of
memory conditions, so that when parsing a query fails due to OOM,
the thread gracefully returns an error.

Before this fix, a new/alloc returning NULL could:
- cause a crash, if dereferencing the NULL pointer,
- produce a corrupted parsed tree, containing NULL nodes,
- alter the semantic of a query, by silently dropping token values or nodes

With this fix:
- C++ constructors are *not* executed with a NULL "this" pointer
when operator new fails.
This is achieved by declaring "operator new" with a "throw ()" clause,
so that a failed new gracefully returns NULL on OOM conditions.

- calls to new/alloc are tested for a NULL result,

- The thread diagnostic area is set to an error status when OOM occurs.
This ensures that a request failing in the server properly returns an
ER_OUT_OF_RESOURCES error to the client.

- OOM conditions cause the parser to stop immediately (MYSQL_YYABORT).
This prevents causing further crashes when using a partially built parsed
tree in further rules in the parser.

No test scripts are provided, since automating OOM failures is not
instrumented in the server.
Tested under the debugger, to verify that an error in alloc_root cause the
thread to returns gracefully all the way to the client application, with
an ER_OUT_OF_RESOURCES error.

client/mysql_upgrade.c:
  Remove Remove unused variable.

client/mysql_upgrade.c:
  Silence warning due to type mismatch.

            
Server side cursors were not initialized properly and this caused a reference to
uninitialized memory.

Fixup mtr_unique. Remove usage of ps and grep. Make it a module. Move _process_alive to Platform.pm. Rename opt_baseport to baseport, it's not an option
