Archive engine returns wrong values for average record length
and max data length.

With this fix they're calculated as following:
- max data length is 2 ^ 63 where large files are supported
  and INT_MAX32 where this is not supported;
- average record length is data length / records in data file.

      
The parser rule for expressions in a udf parameter list contains 
two hacks: 
First, the parser input stream is read verbatim, bypassing 
the lexer.
Second, the Item::name field is overwritten. If the argument to a
udf was a field, the field's name as seen by name resolution was
overwritten this way.
If the field name was quoted or escaped, it would appear as e.g. "`field`".
Fixed by not overwriting field names.

This test case uses mysqlbinlog to dump the content of master-bin.000001,
but the content of master-bin.000001 is not that this test needs.

MTR runs a lot of test cases on one server, so when this test starts, the current binlog file
might not be master-bin.000001, or there are other events are written by tests before.
'RESET MASTER' command must be called at the begin, it ensures that binlog of this test
is wrote to master-bin.000001 correctly.  

Three other tests have the same problem, They were fixed together.
mysqlbinlog-cp932
binlog_incident
binlog_tmp_table

Postfix.
extra/rpl_tests/rpl_row_sp006.test had changed to fix this bug.
extra/rpl_tests/rpl_row_sp006.test is also referenced by rpl_ndb_sp006,
So rpl_row_sp006.result must be changed too.

           The plugin feature is disabled, you need HAVE_DLOPEN

Selectively skip tests that require dynamic loading (ie: static builds).

on subquery inside a SP 

Problem: repeated call of a SP containing an incorrect query with a 
subselect may lead to failed ASSERT().

Fix: set proper sublelect's state in case of error occured during 
subquery transformation.

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

Inserting a negative value in the autoincrement column of a
partitioned innodb table was causing the value of the auto
increment counter to wrap around into a very large positive
value. The consequences are the same as if a very large positive
value was inserted into a column, e.g. reduced autoincrement
range, failure to read autoincrement counter.

The current patch ensures that before calculating the next
auto increment value, the current value is within the positive
maximum allowed limit.

      
Essentially, Bug#45574 results in this bug. The 'CREATE DATABASE IF NOT EXISTS' statement was not 
binlogged, when the database has existed.
Sometimes, the master and slaves become inconsistent. The "CREATE DATABASE
IF NOT EXISTS mysqltest1" statement is not binlogged
if the db 'mysqltest1' existed before the test case is executed. 
So the db 'mysqltest1' can't be created on slave.
     
Patch of Bug#45574 has resolved this problem. 
But I think it is better to replace 'mysqltest1' by default db 'test'.

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

Note: testcase not attached

                    CREATE TABLE...LIKE...
      
The mysql server option 'sync_frm' is ignored when table is created with 
syntax CREATE TABLE .. LIKE.. 
      
Fixed by adding the MY_SYNC flag and calling my_sync() from my_copy() when
the flag is set.

In mysql_create_table(), when the 'sync_frm' is set, MY_SYNC flag is passed 
to my_copy(). 
      
Note: TestCase is not attached and can be tested manually using debugger.

with the newer pb2 testing environments

This fixes the regression introduced in 5.1 that prevents 64 bit builds on Intel while still keeping the core2 hack operational so the cluster can build.

Remove a self assignment.
Rework a few constructs to avoid a potential overflow.
