            mutually-nested subqueries

Queries of the form

  SELECT * FROM (SELECT 1) AS t1,
                (SELECT 2) AS t2,...
                (SELECT 32) AS t32

caused the "Too high level of nesting for select" error
as if the query has a form

  SELECT * FROM (SELECT 1 FROM (SELECT 2 FROM (SELECT 3 FROM...


The table_factor parser rule has been modified to adjust
the LEX::nest_level variable value after every derived table.

Remove commented-out test case. It has been moved to innodb_bug21704.test

  sort_buffer_size cannot allocate

The NULL return from tree_insert() (on low memory) was not
checked for in Item_func_group_concat::add(). As a result
on low memory conditions a crash happens.

Fixed by properly checking the return code.

1. BUG#21704 - Renaming column does not update FK definition

2. Changes in mysql-test/include/mtr_warnings.sql so that the testcase
   for BUG#21704 doesn't fail because of the warnings generated.

branches/5.1:

Fix Bug#21704 Renaming column does not update FK definition

by checking whether a column that participates in a FK definition is being
renamed and denying the ALTER in this case.

The patch was originally developed by Davi Arnaut <Davi.Arnaut@Sun.COM>:
http://lists.mysql.com/commits/77714
and was later adjusted to conform to InnoDB coding style by me (Vasil),
I also added some more comments and moved the bug specific mysql-test to
a separate file to make it more manageable and flexible.

            and base tables 

myrg_attach_children() could reuse a buffer that was allocated 
previously based on a definition of a child table. The problem 
was that the child's definition might have been changed, so 
reusing the buffer could lead to crashes or valgrind errors 
under some circumstances. 
 
Fixed by changing myrg_attach_children() so that the 
rec_per_key_part buffer is reused only when the child table
have not changed, and reallocated otherwise (the old buffer is 
deallocated if necessary).

1. Fixes build warnings caused by applying snapshot 5.1-ss5282

2. Fix the Makefile.am in storage/innobase to remove the header file
   'fsp0types.h' which was added twice to fix build warning generated 
   after applying the 5.1-ss5282 snapshot

branches/5.1: Add missing #include "mtr0log.h" to avoid warnings
when compiling with -DUNIV_MUST_NOT_INLINE.

unnecessarily
      
The problem is that libmysqlclient.so is built with THREAD
undefined, while a client compiling against the same header
files will see THREAD as defined and definitions in
my_pthread.h will be included, possibly resulting in undefined
symbols that cannot be resolved with libmysqlclient.so.
      
The suggested solution is to require that clients wanting to
link with libmysqlclient.so should be built with
MYSQL_CLIENT_NO_THREADS defined. This requires a documentation
change, and more details for this will be supplied if this
patch is approved.
      
The MYSQL_CLIENT_NO_THREADS define was renamed from
UNDEF_THREADS_HACK, to get a more suitable (less suspicious)
name for the define. (The UNDEF_THREADS_HACK is retained for
backwards compatibility, though.)
      
This patch is also in anticipation of WL#4958, which will
remove this problem altogether by dropping the building of
libmysqlclient.

Added code to the .test file to skip this test on Win64 for PB2 stability.
Please remove this code when the bug is fixed.
