A string buffers which were included in the 'view' data structure
were allocated on the stack, causing an invalid pointer when used
after the function returned.
The fix: use copy of values for view->md5 & view->queries

The convert_constant_item function converts a constant to integer using
field for condition like 'field = a_constant'. When the convert_constant_item
is called for a subquery the outer select is already being executed, so
convert_constant_item saves field's value to prevent its corruption.
For EXPLAIN field's value isn't initialized thus when convert_constant_item
tries to restore saved value it fails assertion.
      
Now the convert_constant_item doesn't save/restore field's value
for EXPLAIN.

The abi_check target instroduced as part of WL#4380 verifies
changes to mysql.h. mysql.h in turn includes mysql_version.h.
mysql_version.h is a file that is generated during the configure
phase. We must ensure that mysql_version.h is cleaned only during
distclean and not during clean.

include/Makefile.am:
  This file contains the following changes
  
  1) Moves the cleaning of mysql_version.h from the clean
     phase to the distclean phase.
  
  2) Removes mysql_version.h.in from noinst_HEADERS, this
     entry was reduntant since by virtue of inclusion of
     mysql_version.h mysql_version.h.in is already included.

1. Replace --sleep by wait_* primitive
2. Vertical output for SHOW SLAVE STATUS
3. Updated result file

Problem: mysqld doesn't detect that enum data must be reinserted performing
'ALTER TABLE' in some cases.

Fix: reinsert data altering an enum field if enum values are changed.

Visual Studio 2008 Express edition does not include message compiler mc.exe
It is not possible to build MySQL server if only VC2008 Express is installed,
because we use mc.exe to generate event log messages.

This patch removes the mc.exe dependency. Generated files message.h, 
message.rc and MSG00001.bin  are checked into source code repository.
Instructions on how to add or change messages are added to messages.mc

Added test case to check the default value of @@binlog_format.

mysql-test/t/binlog_format_basic.test:
  Added test case to verify the default binlog_format: it should be
  STATEMENT in 5.1 and MIXED in 6.0.

  Drop table used for test.

The problem was that the server did not robustly handle a
unilateral roll back issued by the Resource Manager (RM)
due to a resource deadlock within the transaction branch.
By not acknowledging the roll back, the server (TM) would
eventually corrupt the XA transaction state and crash.

The solution is to mark the transaction as rollback-only
if the RM indicates that it rolled back its branch of the
transaction.
