0xFF is internal separator for SET|ENUM names. 
If this symbol is present in SET|ENUM names then we replace it with 
','(deprecated symbol for SET|ENUM names) during frm creation
and restore to 0xFF during frm opening

- Fix typo in Item_func_export_set::fix_length_and_dec() which caused character set aggregation to fail
- Remove default argument from last arg of agg_arg_charsets() function, to reduce potential errors

Remove some sql_print_error() calls which were triggered by user error (i.e., not server-level events at all).

Also, convert an sql_print_error -> sql_print_information for a non-error server event.

GROUP BY/DISTINCT pruning optimization must be done before ORDER BY 
optimization because ORDER BY may be removed when GROUP BY/DISTINCT
sorts as a side effect, e.g. in 
  SELECT DISTINCT <non-key-col>,<pk> FROM t1
  ORDER BY <non-key-col> DISTINCT
must be removed before ORDER BY as if done the other way around
it will remove both.

BUG#21077: Possible crash caused by invalid sequence of handler::* calls:                                                
The crash was caused by invalid sequence of handler::** calls:                                                           
  ha_smth->index_init();                                                                                                 
  ha_smth->index_next_same(); (2)                                                                                        
(2) is an invalid call as it was not preceeded by any 'scan setup' call
like index_first() or index_read(). The cause was that QUICK_SELECT::reset()
didn't "fully reset" the quick select- current QUICK_RANGE wasn't forgotten,
and quick select might attempt to continue reading the range, which would
result in the above mentioned invalid sequence of handler calls.

5.x versions are not affected by the bug - they already have the missing
"range=NULL" clause.

  bug #18184  SELECT ... FOR UPDATE does not work..: New test case

  Fix for bug #21059  Server crashes on join query with large dataset with NDB tables: Releasing operation for each intermediate batch, before next call to trans->execute(NoCommit);

  - if there are two character set definitions in the column declaration,
    we replace the first one with the second one as we store both in the LEX->charset
    slot. Add a separate slot to the LEX structure to store underscore charset.
  - convert default values to the column charset of STRING, VARSTRING fields 
    if necessary as well.

Socket timeouts in client library were used only on Windows.

The solution is to use socket timeouts in client library on all
systems were they are supported.

No test case is provided because it is impossible to simulate network
failure in current test suit.

Fixed by moving update_key_parts() down to be after write_index().

Make the encryption functions MD5(), SHA1() and ENCRYPT() return binary results.
    
Make MAKE_SET() and EXPORT_SET() use the correct character set for their default separator strings.

didn't work as expected: collation_server was set not to xxx,
but to the default collation of character set "yyy".
    
With different argument order it worked as expected:
mysqld --character-set-server=yyy --collation-server=yyy 
    
Fix:
initializate default_collation_name to 0
when processing --character-set-server
only if --collation-server has not been specified
in command line.

--with-collation worked only on the server side.
Client side ignored this argument, so collation_connection
was not properly set (remained latin1_swedish_ci).

time_format() claimed %H and %k would return at most two digits
(hours 0-23), but this coincided neither with actual behaviour
nor with docs.  this is not visible in simple queries; forcing
a temp-table is probably the easiest way to see this.  adjusted
the return-length appropriately; the alternative would be to
adjust the docs to say that behaviour for > 99 hours is undefined.

Problem described in this bug report affects MyISAM tables only.

Running mysqld --flush instructs mysqld to sync all changes to disk
after each SQL statement. It worked well for INSERT and DELETE
statements, but it did sync for UPDATE only in case if there was
index change (change of colum that has an index). If no updated column
has an index, data wasn't synced to disk.

This fix makes UPDATE statement to sync data to disk even if there is
no index change (that is only data change) and mysqld is run with
--flush option.
