Server side cursors were not initialized properly and this caused a reference to
uninitialized memory.

	running on Windows

We used two OS-specific methods of looking up the executable 
name, which don't work outside of those two kinds of OSes 
(Linux+Solaris and Windows).

We assume that if the user ran this program with a certain 
name, we can run the other sibling programs with a similar name.

(re-patch in bzr)

Post-merge fix: remove spurious semicolon that caused the function
to return failure regardless of the outcome.

Fall back to "find" if bzr is unavailable.

Don't fail for paths that have spaces in them.

bk sfiles -> bzr ls

Post-merge fix: Alter linking order so that the thread linking
flags appear last in the list. This needs to be done this way
because some linkers will not search the thread archive again
if a undefined symbol (pthread_kill in this case) appears later.

      
Reset session sql_mode before creating system tables as it
is done in the mysql_fix_privilege_tables.sql script.

      
min() and max() functions are implemented in MySQL as macros.
This means that max(a,b) is expanded to: ((a) > (b) ? (a) : (b))
Note how 'a' is quoted two times.
Now imagine 'a' is a recursive function call that's several 10s of levels deep.
And the recursive function does max() with a function arg as well to dive into
recursion.
This means that simple function call can take most of the clock time.
Identified and fixed several such calls to max()/min() : including the IF() 
sql function implementation.

      
Community contribution fix for Serbian translation in error message list.

Fixed typo and removed duplicate call to get_current_user.

config/ac-macros/character_sets.m4 didn't mention hungarian collations
in the UTF8 and UCS2 lists.

Calling List<Cached_item>::delete_elements for the same list twice
caused a crash of the server in the function JOIN::cleaunup.
Ensured that delete_elements() in JOIN::cleanup would be called only once.

Removing duplicate 'setup' portions of these include files.  Likely an editor error created dupe lines.
This is causing many Pushbuild errors

     
Tables in the table definition cache are keeping a cache buffer for blob
fields which can consume a lot of memory.
    
This patch introduces a maximum size threshold for these buffers.

BUG#37884: rpl_row_basic_2myisam and rpl_row_basic_3innodb fail sporadically in pushbuild
These have been fixed in 5.1-rpl. Re-applying fix for BUG#37884
in 5.1-bugteam, and disabling rpl_flushlog_loop for BUG#37733 in
5.1-bugteam.

                  
Range scan in descending order for c <= <col> <= c type of
ranges was ignoring the DESC flag.
However some engines like InnoDB have the primary key parts 
as a suffix for every secondary key.
When such primary key suffix is used for ordering ignoring 
the DESC is not valid.
But we generally would like to do this because it's faster.
            
Fixed by performing only reverse scan if the primary key is used.
Removed some dead code in the process.
