returns incorrect result with large decimal value" 
 
For the DIV operator, neither operands nor result were checked 
for integer overflows. 
 
This patch changes the DIV behavior for non-integer operands as 
follows: if either of the operands has a non-integer type, 
convert both operands to the DECIMAL type, then calculate the 
division using DECIMAL arithmetics. Convert the resulting 
DECIMAL value into BIGINT [UNSIGNED] if it fits into the 
corresponding range, or throw an 'out of range' error 
otherwise.

  Fix for Bug#40128: drop-no_root fails under windows in 6.0-rpl.
  
  The problem was that directories with no permission (000) files
  are deleted differently on UNIX and on Windows.
  
  On UNIX, 000-permission file is deleted perfectly, but other files
  are left in the directory.
  
  On Windows, 000-permission file is not deleted, but other files
  are deleted.
  
  Also, the fix needed a change in mysqltest.c: 'chmod' directive
  should return a positive error code (in order to be handled).
  It's decided to return a constant '1' for all error codes
  just to be OS-independent.

  A fix for Bug#26704: Failing DROP DATABASE brings
  mysql-client out of sync.

  The problem was that we changed current database w/o caring
  whether it was dropped successfully or not.

  The fix is not to change current database if we failed to drop it.

Backport of the fix for BUG#33730 "Full table scan instead selected partitions for query more than 10 partitions"
from 6.0, made in sergefp@mysql.com-20090205190644-q8632sniogedhtsu

(from revision konstantin@mysql.com-20080627154042-923m6lzk7z77lrgj ). This moves the slow part
(10 seconds over 13) into a separate big test.

2. Mark ndb, rpl_ndb test suites experimental.

Revision:

removed instances of __NT__ from code. We now only build "NT" binaries

Cleanup pthread_self(), pthread_create(), pthread_join() implementation on Windows.
Prior implementation is was unnecessarily complicated and even differs in embedded
and non-embedded case.
      
Improvements in this patch:
* pthread_t is now the unique thread ID, instead of HANDLE returned by beginthread
      
This simplifies pthread_self() to be just straight GetCurrentThreadId().
prior it was much  art involved in passing the beginthread() handle from the caller
to the TLS structure in the child thread ( did not work for the main thread of
course)
      
* remove MySQL specific my_thread_init()/my_thread_end() from pthread_create.
No automagic is done on Unix on pthread_create(). Having the same on Windows will 
improve portability and avoid extra #ifdef's
      
* remove redefinition of getpid() - it was defined as GetCurrentThreadId()
