In create_myisam_from_heap() mark all errors as fatal except 
HA_ERR_RECORD_FILE_FULL for a HEAP table.

Not doing so could lead to problems, e.g. in a case when a
temporary MyISAM table gets overrun due to its MAX_ROWS limit
while executing INSERT/REPLACE IGNORE ... SELECT. 
The SELECT execution was aborted, but the error was 
converted to a warning due to IGNORE clause, so neither 'ok' 
nor 'error' packet could be sent back to the client. This 
condition led to hanging client when using 5.0 server, or 
assertion failure in 5.1.

Problem was that a failing rename just left the partitions at the state
it was at the failure.

Solution was to try to revert the started rename if a failure occured.

Errors encountered during initialization of the SSL subsystem
are printed to stderr, rather than to the error log.
        
This patch adds a parameter to several SSL init functions to
report the error (if any) out to the caller. The function
init_ssl() in mysqld.cc is moved after the initialization of
the log subsystem, so that any error messages can be logged to
the error log. Printing of messages to stderr has been 
retained to get diagnostic output in a client context.

binlog
      
The fix for BUG 43929 introduced a regression issue. In a nutshell, when a
statement that changes a non-transactional table fails, it is written to the
binary log with the error code appended. Unfortunately, after BUG 43929, this
failure was flushing the transactional chace causing mismatch between execution
and logging histories. To fix this issue, we avoid flushing the transactional
cache when a commit or rollback is not issued.

When during the optimization an item is moved to the upper select
the item's context left unchanged. This caused wrong result in the 
PS/SP mode.
The Item_ident::remove_dependence_processor now sets the context
of the select to which the item is moved to.

Append the patch for resolving the problems, which have been brought by commiting bug#45214.

In a subselect all fields from outer selects are marked as dependent on
selects they are belong to. In some cases optimizer substitutes it for an
equivalent expression. For example "a_field IN (SELECT outer_field)" is
substituted with "a_field = outer_field". As we moved the outer_field to the
upper select it's not really outer anymore. But it was left marked as outer.
If exists an index over a_field optimizer choose wrong execution plan and thus
return wrong result.

Now the Item_in_subselect::single_value_transformer function removes dependent
marking from fields when a subselect is optimized away.

       
Fixed various compilation warnings when compiling on a 
 64 bit windows.

        
The "get_master_version_and_clock(...)" function in sql/slave.cc ignores 
error and passes directly when queries fail, or queries succeed 
but the result retrieved is empty.
  
The "get_master_version_and_clock(...)" function should try to reconnect master
if queries fail because of transient network problems, and fail otherwise.
The I/O thread should print a warning if the some system variables do not 
exist on master (very old master)

          table

The MERGE table storage engine does not support the HA_CAN_SQL_HANDLE feature
and any attempt to open the merge table will fail with ER_ILLEGAL_HA.

After an error occurred the tables that was opened must be closed again
or they will be left in an inconsistent state. However, the assumption
made in the code for closing and register handler tables was that only
one table will be opened, and this is not true for MERGE tables which
will cause multiple tables to open.

The next time a SELECT operation was issued on the merge table it
caused the system to freeze.

This patch fixes this issue by making sure that all tables which
are opened also are closed in the event of an error.

Merge Konstantin's patch and add a test case.

Do not assume that SQL prepared statements always run in text protocol.
When invoked from a stored procedure, which is itself invoked
by means of prepared CALL statement, the protocol may be binary.
Juggle with the protocol only when we want to change it
to binary in COM_STMT_EXECUTE, COM_STMT_PREPARE.

This is a backport from 5.4/6.0, where the bug was fixed
as part of WL#4264 "Backup: Stabilize Service Interface" 

Fixed the following problems:
1. cmake 2.6 warning because of a changed default on
how the dependencies to libraries with a specified 
path are resolved.
Fixed by requiring cmake 2.6.
2. Removed an obsolete pre-NT4 hack including defining
Windows system defines to alter the behavior of windows.h.
3. Disabled warning C4065 on compiling sql_yacc.cc because
of a know incompatibility in some of the newer bison binaries.
