Put variable declaration at the beginning of a block

                    Removes the need of a hack (the jump to label).

On Mac OS X or Windows, sending a SIGHUP to the server or a
asynchronous flush (triggered by flush_time), would cause the
server to crash.

The problem was that a hook used to detach client API handles
wasn't prepared to handle cases where the thread does not have
a associated session.

The solution is to verify whether the thread has a associated
session before trying to detach a handle.

Make configure.js bail with an error if trying to build bdb from a bzr
tree.

          'flush tables' crashes

The server crashes when 'show procedure status' and 'flush tables' are
run concurrently.

This is caused by the way mysql.proc table is added twice to the list
of table to lock although the requirements on the current locking API
assumes differently.

No test case is submitted because of the nature of the crash which is 
currently difficult to reproduce in a deterministic way.

This is a backport from 5.1

The 'BEGIN/COMMIT/ROLLBACK' log event could be filtered out if the
database is not selected by --database option of mysqlbinlog command.
This can result in problem if there are some statements in the
transaction are not filtered out.

To fix the problem, mysqlbinlog will output 'BEGIN/ROLLBACK/COMMIT' 
in regardless of the database filtering rules.

          replication
              
MySQL server uses wrong lock type (always TL_READ instead of
TL_READ_NO_INSERT when appropriate) for tables used in
subqueries of UPDATE statement. This leads in some cases to
a broken replication as statements are written in the wrong
order to the binlog.

Add --help option.

   Solaris binary packages should be compiled with '-g0', not '-g'

 query
      
The fix for bug 46749 removed the check for OUTER_REF_TABLE_BIT 
and substituted it for a check on the presence of 
Item_ident::depended_from.
Removing it altogether was wrong : OUTER_REF_TABLE_BIT should 
still be checked in addition to depended_from (because it's not 
set in all cases and doesn't contradict to the check of depended_from).
Fixed by returning the old condition back as a compliment to the 
new one.

 - Create the "dummy" thread joinable and wait for it to
   exit before continuing in 'my_thread_global_init'
 - This way we know that the pthread library is initialized
   by one thread only

    Solaris binary packages should be compiled with '-g0', not '-g'

The main fix for this is done in the build tools,
but in the sources it affects "configure.in"
which sets "DEBUG_CXXFLAGS" to be used in all debug builds.

      
Initialize correctly client flags for the embedded client
Test cases in jp updated to work correctly with embedded server.

When parsing the service installation parameter in 
default_service_handling() make sure the value of the
optional parameter doesn't overwrite it's name.

with gcc 4.3.2
      
This is the fifth patch cleaning up more GCC warnings about
variables used before initialized using the new macro
UNINIT_VAR().

The problem is that argument buffer can be used as result buffer
and it leads to argument value change.
The fix is to use 'old buffer' as result buffer only
if first argument is not constant item.

Updates the results of all the out-dated test suites and adds 
the special mysqltest command to enable innodb for the tests that need it.

            can crash under load

Backport from 5.1.
Does also include key cache fixes from:
Bug 44068 (RESTORE can disable the MyISAM Key Cache)
Bug 40944 (Backup: crash after myisampack)

Memory allocated in TMP_TABLE_PARAM::copy_field is not cleaned up.
The fix is to clean up TMP_TABLE_PARAM::copy_field array in JOIN::destroy.

                    name as existing view

When trying to create a table with the same name as existing view with
join, mysql server crashes.

The problem is when create table is issued with the same name as view, while
verifying with the existing tables, we assume that base table object is 
created always.

In this case, since it is a view over multiple tables, we don't have the 
mysql derived table object.

Fixed the logic which checks if there is an existing table to not to assume
that table object is created when the base table is view over multiple 
tables.

                                for CREATE TABLE...LIKE...

Add my_sync.c to mysqltest sources list in CMakeLists.txt

myisamchk tool generates warnings when run on an myisam files (.MYI or .MYD)
This is because of the conversion of max_value for certain options in myisamchk 
from singed long to unsigned long

The max value for the options key_buffer_size, read_buffer_size, write_buffer
_size and sort_buffer_size is given as (long) ~0L which becomes -1  when casted
from signed long to longlong and then casted to ulonglong. When (ulonglong) -1 
is compared with maximal value for GET_ULONG data type, we adjust it to 
(ulonglong) ULONG_MAX and throw the warning.

Fixed by using the right max size.

Max values for the variables (from mysqld.cc)
----------------------------
1. key_buffer_size
   5.0: ULONG_MAX
   5.1: SIZE_T_MAX
   6.0: SIZE_T_MAX

2. read_buffer_size and write_buffer_size
   5.0: INT_MAX32
   5.1: INT_MAX32
   6.0: INT_MAX32

3. sort_buffer_size (aka myisam_sort_buffer_size)
   5.0: UINT_MAX32
   5.1: ULONG_MAX
   6.0: ULONG_MAX
