Fix for broken --with-csv-storage-engine build.

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().

   Currently new_data will not have an updated auto_increament record, or
   and updated timestamp field. You can do these for example by doing these:
-  if (table->timestamp_on_update_now)
-    update_timestamp(new_row+table->timestamp_on_update_now-1);
+  if (table->timestamp_field_type & TIMESTAMP_AUTO_SET_ON_UPDATE)
