Overview of locking checking:

2. Check to see which tables need WRITE lock
3. Unlock tables and relock

Now we are setting Field_timestamp::field_length to 19 in open_table()
if we are in new mode (and we are restoring it back when we are coming
back to normal mode). This also should solve potential problems with
some of LOAD DATA INFILE and SELECT * INTO in this mode.
mysql-test/r/type_timestamp.result:
Added test for bug #4131 'TIMESTAMP columns missing minutes and seconds
when using GROUP BY' and other --new mode related behavior.
mysql-test/t/type_timestamp.test:
Added test for bug #4131 'TIMESTAMP columns missing minutes and seconds
when using GROUP BY' and other --new mode related behavior.
sql/field.cc:
Added Field_timestamp::orig_field_length member for saving original
field_length value, because this member can be modified if new_mode is
in effect.
Lot of Field_timestamp code simplified and Field_timestamp::make_field()
is no longer needed because we are setting field_length to 19 if we are
in --new mode now.
sql/field.h:
Added Field_timestamp::orig_field_length member for saving original
field_length value, because this member can be modified if new_mode
is in effect.
Field_timestamp::make_field() is no longer needed because we are setting
field_length to 19 if we are in --new mode now.
sql/sql_base.cc:
If --new mode is in effect all TIMESTAMP fields should pretend that they
have length of 19. We are achieving this by setting
Field_timestamp::field_length to 19 (or original value) in open_table().
We are using TABLE::timestamp_mode variable for avoiding of unnecessary
looping over all fields of the table and setting field_length if table
was used with same new_mode value before.
Note: We do not introduce general framework for setting up Field objects
for usage with current THD here because this fix is only needed in 4.0
and Monty said that we will also remove looping over all fields when
updating table_name member at some point. This more general framework
will also complicate nice optimization with avoiding of unneeded looping.
sql/sql_parse.cc:
Now when we are creating TIMESTAMP(19) fields by default in --new mode,
otherwise we will have unaligned behavior between ALTER and CREATE.
sql/table.h:
Added TABLE::timestamp_mode field for saving information whenever we set
field_length members of table's TIMESTAMP fields to 19 (to honor
new_mode) or they have original values.

make setup_copy_fields to insert Item_copy_string for blobs in

the thing is that Item_copy_string::copy for function can call
Item_copy_string::val_int for blob via Item_ref.
But if Item_copy_string::copy for blob isn't called before,
it's value will be wrong.
