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.

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.


mysql-test/r/alter_table.result:
  Fix for bug#23113: Different behavior on altering ENUM fields between 5.0 and 5.1
    - test result.
mysql-test/t/alter_table.test:
  Fix for bug#23113: Different behavior on altering ENUM fields between 5.0 and 5.1
    - test case.
sql/field.cc:
  Fix for bug#23113: Different behavior on altering ENUM fields between 5.0 and 5.1
    - Field_enum::is_equal() introduced, which is called to detect that a field
  is changing by 'ALTER TABLE'.
sql/field.h:
  Fix for bug#23113: Different behavior on altering ENUM fields between 5.0 and 5.1
    - Field_enum::is_equal() introduced, which is called to detect that a field
  is changing by 'ALTER TABLE'.

- Make send_row_on_empty_set() return FALSE when simplify_cond() has found out
  that HAVING is always FALSE
re-committing to put the fix into 5.0 and 5.1

mysql-test/r/group_by.result:
  BUG#38072: Wrong result: HAVING not observed in a query with aggregate

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.

mysql-test/r/xa.result:
  Update test case result.
mysql-test/t/xa.test:
  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.

mysql-test/r/xa.result:
  Add test case result for Bug#28323
mysql-test/t/xa.test:
  Add test case for Bug#28323
sql/handler.cc:
  Reset XID only at the end of the global transaction.
sql/share/errmsg.txt:
  Add new error codes.
sql/sql_class.h:
  Remember the error reported by the Resource Manager.
sql/sql_parse.cc:
  Rollback the transaction if the Resource Manager reported
  a error and rolled back its branch of the transaction.

Debug builds of MySQL 5.1, 6.0 with Sun Studio 12 broke because of
use of gcc specific feature.
            
The fix is to replace __FUNCTION__ with the corresponding character string

Fixed .test file, re-recorded .result file

Ensured reset of system variables at the end of subtests.

Server crashed during a sort order optimization
of a dependent subquery:

SELECT
    (SELECT t1.a FROM t1, t2
      WHERE t1.a = t2.b AND t2.a = t3.c
      ORDER BY t1.a)
  FROM t3;


Bitmap of tables, that the reference to outer table
column uses, in addition to the regular table bit
has the OUTER_REF_TABLE_BIT bit set.
The only_eq_ref_tables function traverses this map
bit by bit simultaneously with join->map2table list.
Obviously join->map2table never contains an entry
for the OUTER_REF_TABLE_BIT pseudo-table, so the
server crashed there.


The only_eq_ref_tables function has been modified
to traverse regular table bits only like the
update_depend_map function (resetting of the
OUTER_REF_TABLE_BIT there is enough, but
resetting of the whole set of PSEUDO_TABLE_BITS
is used there for sure).


mysql-test/r/order_by.result:
  Added test case for bug #39844.
mysql-test/t/order_by.test:
  Added test case for bug #39844.

Added the missing DROP TABLE
