enabled message storing into error message list
for 'drop table' command

contains ONLY_FULL_GROUP_BY

The partitioning code needs to issue a Item::fix_fields()
on the partitioning expression in order to prepare 
it for being evaluated.
It does this by creating a special table and a table list 
for the scope of the partitioning expression.
But when checking ONLY_FULL_GROUP_BY the 
Item_field::fix_fields() was relying that there always be
cached_table set and was trying to use it to get the 
select_lex of the SELECT the field's table is in.
But the cached_table was not set by the partitioning code
that creates the artificial TABLE_LIST used to resolve the
partitioning expression and this resulted in a crash.
 
Fixed by rectifying the following errors :
1. Item_field::fix_fields() : the code that check for 
ONLY_FULL_GROUP_BY relies on having tables with 
cacheable_table set. This is mostly true, the only 
two exceptions being the partitioning context table
and the trigger context table.
Fixed by taking the current parsing context if no pointer
to the TABLE_LIST instance is present in the cached_table.

2. fix_fields_part_func() : 

2a. The code that adds the table being created to the 
scope for the partitioning expression is mostly a copy 
of the add_table_to_list and friends with one exception :
it was not marking the table as cacheable (something that
normal add_table_to_list is doing). This caused the 
problem in the check for ONLY_FULL_GROUP_BY in 
Item_field::fix_fields() to appear.
Fixed by setting the correct members to make the table
cacheable.
The ideal structural fix for this is to use a unified 
interface for adding a table to a table list 
(add_table_to_list?) : noted in a TODO comment

2b. The Item::fix_fields() was called with a NULL destination
pointer. This causes uninitalized memory reads in the 
overloaded ::fix_fields() function (namely 
Item_field::fix_fields()) as it expects a non-zero pointer 
there. Fixed by passing the source pointer similarly to how 
it's done in JOIN::prepare().

Details:
- Add "sync_slave_with_master" at test end
- Restore the initial value of log_bin_trust_function_creators

Creating an IBMDB2I table with the macce character set
is successful, but any attempt to insert data into the
table was failing.

This was happening because the character set name "macce"
is not a valid iconv descriptor for IBM i PASE. This patch
adds an override to convertTextDesc to use the equivalent
valid iconv descriptor "IBM-1282" instead.

without proper formatting
      
The problem is that a suitably crafted database identifier
supplied to COM_CREATE_DB or COM_DROP_DB can cause a SIGSEGV,
and thereby a denial of service. The database name is printed
to the log without using a format string, so potential
attackers can control the behavior of my_b_vprintf() by
supplying their own format string. A CREATE or DROP privilege
would be required.
      
This patch supplies a format string to the printing of the
database name. A test case is added to mysql_client_test.

After applying Innodb snapshot 5.1-ss5282, build was broken
because of missing header file. 

Adding the header file to Makefile.am after informing the 
innodb developers.

Add new header to Makefile.am so it gets bundled.

After applying the innodb snapshot 5.0-ss5406 for bug#40565, the windows push build
tests failed because of the missing cast of void * pointer in row0sel.c file

Informed the innodb developers and received patch by email.

Some collations--including cp1250_czech_cs,latin2_czech_cs,
ucs2/utf8_czech_ci, ucs2/utf8_danish_ci--are not being
sorted correctly by the IBMDB2I storage engine. This
was being caused because the sort order used by DB2 is
incompatible with the order expected by MySQL.

This patch removes support for the cp1250_czech_cs and
latin2_czech_cs collations because it has been determined
that the sort order used by DB2 is incompatible with the
order expected by MySQL. Users needing a czech collation
with IBMDB2I are encouraged to use a Unicode-based collation 
instead of these single-byte collations. This patch also
modifies the DB2 sort sequence used for ucs2/utf8_czech_ci
and ucs2/utf8_danish_ci collations to better match the
sorting expected by MySQL. This will only affect indexes
or tables that are newly created through the IBMDB2I storage
engine. Existing IBMDB2I tables will retain the old sort
sequence until recreated.

           format." warnings
      
Despite the fact that a statement would be filtered out from binlog, a
warning would still be thrown if it was issued with the LIMIT.
      
This patch addresses this issue by checking the filtering rules before
printing out the warning.

The TABLE::reginfo.impossible_range is used by the optimizer to indicate
that the condition applied to the table is impossible. It wasn't initialized
at table opening and this might lead to an empty result on complex queries:
a query might set the impossible_range flag on a table and when the query finishes,
all tables are returned back to the table cache. The next query that uses the table
with the impossible_range flag set and an index over the table will see the flag
and thus return an empty result.

The open_table function now initializes the TABLE::reginfo.impossible_range
variable.

Logging to slow log can produce an undetermined value for
Rows_examined in special cases. In debug mode this manifests
itself as any of the various marker values used to mark
uninitialized memory on various platforms.

If logging happens on a THD object that hasn't performed any
row reads (on this or any previous connections), the
THD::examined_row_count may be uninitialized. This patch adds
initialization for this attribute.

No automated test cases are added, as for this to be
meaningful, we need to ensure that we're using a THD
fulfilling the above conditions. This is hard to do in the
mysql-test-run framework. The patch has been verified
manually, however, by restarting mysqld and running the test
included with the bug report.

The problem is that the one phase commit function failed to
properly end a empty transaction. The solution is to ensure
that the transaction cleanup procedure is invoked even for
empty transactions.

The test case added failed sporadically on PB. This is due to the
fact that the user thread in some cases is waiting for slave IO
to stop and then check the error number. Thence, sometimes the
user thread would race for the error number with IO thread.

This post push fix addresses this by replacing the wait for slave
io to stop with a wait for slave io error (as it seems it was
added in 6.0 also after patch on which this is based was
pushed). This implied backporting wait_for_slave_io_error.inc
from 6.0 also.
