Problem description:
When a view is created using function FORMAT and if FORMAT function uses locale
option,definition of view saved into server doesn't contain that locale information,
Ex:
create  table test2 (bb decimal (10,2));
insert into test2 values (10.32),(10009.2),(12345678.21);
create view test3 as select format(bb,1,'sk_SK') as cc from test2;
select * from test3;
+--------------+
| cc           |
+--------------+
| 10.3         |
| 10,009.2     |
| 12,345,678.2 |
+--------------+
3 rows in set (0.02 sec)

show create view test3
                View: test3
         Create View: CREATE ALGORITHM=UNDEFINED DEFINER=`root`@`localhost`
SQL SECURITY DEFINER VIEW `test3` AS select format(`test2`.`bb`,1) AS `cc`
from `test2`
character_set_client: latin1
collation_connection: latin1_swedish_ci
1 row in set (0.02 sec)

Problem Analysis:
The function Item_func_format::print() which prints the query string to create
the view does not print the third argument (i.e the locale information). Hence
 view is created without locale information. 

Problem Solution:
If argument count is more than 2 we now print the third argument onto the query string.

bug#13437900
post-push changes to please solaris compiler.

Also added tests for partitions key caches.

There was memory leak when running some tests on PB2.
The reason of the failure is an early return from change_master()
that was supposed to deallocate a dyn-array.

Actually the same bug58915 was fixed in trunk with relocating the dyn-array
destruction into THD::cleanup_after_query() which can't be bypassed.
The current patch backports magne.mahre@oracle.com-20110203101306-q8auashb3d7icxho
and adds two optimizations: were done: the static buffer for the dyn-array to base on,
and the array initialization is called precisely when it's necessary rather than
per each CHANGE-MASTER as before.

  the test is binlog-format insensitive so it will be run with MIXED mode only.

the new --slow-start-timeout option's help output

Added a global read-only option slow-start-timeout to control the
Windows service control manager's service start timeout, that was
currently hard-coded to be 15 seconds.
The default of the new option is 15 seconds.
The timeout can also be set to 0 (to mean no timeout applicable).

The counter handler_read_key (SSV::ha_read_key_count) is incremented 
incorrectly.

The mysql server maintains a per thread system_status_var (SSV)
object.  This object contains among other things the counter
SSV::ha_read_key_count. The purpose of this counter is to measure the
number of requests to read a row based on a key (or the number of
index lookups).

This counter was wrongly incremented in the
ha_innobase::innobase_get_index(). The fix removes
this increment statement (for both innodb and innodb_plugin).

The various callers of the innobase_get_index() was checked to
determine if anybody must increment this counter (if they first call
innobase_get_index() and then perform an index lookup).  It was found
that no caller of innobase_get_index() needs to worry about the
SSV::ha_read_key_count counter.

SMALL KEY CACHE

The server crashed on division by zero because the key cache was not
initialized and the block length was 0 which was used in a division.

The fix was to not allow CACHE INDEX if the key cache was not initiallized.
Thus never try LOAD INDEX INTO CACHE for an uninitialized key cache.

Also added some windows files/directories to .bzrignore.

When printing information about a ROW_FORMAT=REDUNDANT record, pass
the correct flag to rec_get_next_offs().

rb:821 approved by Jimmy Yang

This bug ensures that a live downgrade from an InnoDB 5.6 with WL5756 and
a database created with innodb-page-size=8k or 4k will make a version 5.5
installation politely refuse to start. Instead of crashing or giving some
indication about a corrupted database, it will indicate the page size
difference. 

This patch takes only that part of the Wl5756 patch that is needed to
protect against opening a tablespace that is stamped with a different
page size.

It also contains the change in dict_index_find_on_id_low() just in case
a database with another page size is created by recompiling a pre-WL5756
InnoDB.

WITH FOREIGN KEY CONSTRAI

WITH LARGE BUFFER POOL

(Note: this a backport of revno:3472 from mysql-trunk)

rb://845
approved by: Marko

  When dropping a table (with an .ibd file i.e.: with
  innodb_file_per_table set) we scan entire LRU to invalidate pages from
  that table. This can be painful in case of large buffer pools as we hold
  the buf_pool->mutex for the scan. Note that gravity of the problem does
  not depend on the size of the table. Even with an empty table but a
  large and filled up buffer pool we'll end up scanning a very long LRU
  list.
  
  The fix is to scan flush_list and just remove the blocks belonging to
  the table from the flush_list, marking them as non-dirty. The blocks
  are left in the LRU list for eventual eviction due to aging. The
  flush_list is typically much smaller than the LRU list but for cases
  where it is very long we have the solution of releasing the
  buf_pool->mutex after scanning 1K pages.
  
  buf_page_[set|unset]_sticky(): Use new IO-state BUF_IO_PIN to ensure
  that a block stays in the flush_list and LRU list when we release
  buf_pool->mutex. Previously we have been abusing BUF_IO_READ to achieve
  this.

The predicate is re-written from
((`test`.`g1`.`a` = geometryfromtext('')) or ...
to
((`test`.`g1`.`a` = <cache>(geometryfromtext(''))) or ...

The range optimizer calls save_in_field_no_warnings, in order to fetch keys.
save_in_field_no_warnings returns 0 because of the cache wrapper,
and get_mm_leaf() proceeded to call Field_blob::get_key_image() 
which accesses un-initialized data.

******

Refactored the test case: hardened and extended it. Created test inc file
to abstract the task of relocating binlogs.

Also, disabled it on windows for not cluttering the test case any further, 
as it depends heavily on doing filesystem operations and path handling.

mysql-test/include/relocate_binlogs.inc:
  Auxiliar include file that performs the relocation of binary logs
  listed in an index file.

Post-push fix: build break on windows/optimized
