such column should be set to current timestamp on both INSERT and UPDATE
operations, and we don't call this method for rest of them).

column types TIMESTAMP is NOT NULL by default, so in order to have
TIMESTAMP column holding NULL valaues you have to specify NULL as
one of its attributes (this needed for backward compatibility).
Main changes:
Replaced TABLE::timestamp_default_now/on_update_now members with
TABLE::timestamp_auto_set_type flag which is used everywhere
for determining if we should auto-set value of TIMESTAMP field
during this operation or not. We are also use Field_timestamp::set_time()
instead of handler::update_timestamp() in handlers.
mysql-test/r/type_timestamp.result:
Added test for TIMESTAMP columns which are able to store NULL values.
mysql-test/t/type_timestamp.test:
Added test for TIMESTAMP columns which are able to store NULL values.
sql/field.cc:
Added support for TIMESTAMP fields holding NULL values.
We don't need Field_timestamp::set_timestamp_offsets() anymore.
Instead we need Field_timestamp::get_auto_set_type() function
which will convert TIMESTAMP auto-set type stored in Field in
unireg_check to value from timestamp_auto_set_type_enum.
(We can't replace this function with additional Field_timestamp member
and some code in constructor because then we will have troubles
with Field::new_field() method).
We should also set field to not null in Field_timestamp::set_time() now.
sql/field.h:
Added support for TIMESTAMP fields holding NULL values.
We don't need Field_timestamp::set_timestamp_offsets() anymore.
Instead we need Field_timestamp::get_auto_set_type() function,
which will convert TIMESTAMP auto-set type stored in Field in
unireg_check to value from timestamp_auto_set_type_enum.
We also have to support NULL values in Field_timestamp::get_timestamp()
function.
sql/field_conv.cc:
Added comment clarifying behavior in case of TIMESTAMP fields which are
able to store NULL values.
sql/ha_berkeley.cc:
Now we use TABLE::timestamp_field_type instead of
TABLE::timestamp_default_now/on_update_now for determining
if we should auto-set value of TIMESTAMP field during this operation.
We are also use Field_timestamp::set_time() instead of
handler::update_timestamp().
sql/ha_heap.cc:

handler::update_timestamp().
sql/ha_innodb.cc:

handler::update_timestamp().
sql/handler.cc:
handler::update_timestamp() is no longer needed since now we use
Field_timestamp::set_time() instead.
(we can't use handler::update_timestamp() anyway since field position
only is not enough for TIMESTAMP fields which are able to store NULLs)
sql/handler.h:
handler::update_timestamp() is no longer needed since now we use
Field_timestamp::set_time() instead.
sql/item_timefunc.cc:
Since now TIMESTAMP fields can hold NULL values we should take this into
account.
sql/sql_base.cc:
Now we use TABLE::timestamp_field_type instead of
TABLE::timestamp_default_now/on_update_now.
(Here we use Field_timestamp::get_auto_set_type() to setup its value
before further statement execution).
sql/sql_insert.cc:
Now we use TABLE::timestamp_field_type instead of
TABLE::timestamp_default_now/on_update_now.
sql/sql_load.cc:
Now we use TABLE::timestamp_field_type instead of
TABLE::timestamp_default_now/on_update_now.
sql/sql_parse.cc:
Added support for TIMESTAMP fields holding NULL values.
We should distinguish NULL default values and non-specified default
values for such fields (because latter could mean DEFAULT NOW()
ON UPDATE NOW() in some cases).
sql/sql_show.cc:
Added support for TIMESTAMP fields holding NULL values.
Unlike all other fields these are NOT NULL by default
so we have to specify NULL attribute explicitly for them.
sql/sql_table.cc:
Now we use TABLE::timestamp_field_type instead of
TABLE::timestamp_default_now/on_update_now.
sql/sql_update.cc:
Now we use TABLE::timestamp_field_type instead of
TABLE::timestamp_default_now/on_update_now.
sql/sql_yacc.yy:
Added support for TIMESTAMP fields holding NULL values.
Unlike all other fields these are NOT NULL by default
(so we have to set NOT_NULL_FLAG properly for them).
sql/table.h:
Added timestamp_auto_set_type enum which values are used for indicating
during which operations we should automatically set TIMESTAPM field
value to current timestamp.
TABLE: Replaced timestamp_default_now/on_update_now members with
timestamp_auto_set_type flag (Now when TIMESTAMP field are able to
store NULL values, single position of field in record is not enough
for updating this field anyway).
