The problem was that when convert_constant_item is called for subqueries,
this happens when we already started executing the top-level query, and
the field argument of convert_constant_item pointed to a valid table row.
In turn convert_constant_item used the field buffer to compute the value
of its item argument. This copied the item's value into the field,
and made equalities with outer references always true.
  
The fix saves/restores the original field's value when it belongs to an
outer table.

The Item_func_set_user_var::register_field_in_read_map() did not check 
that the result_field was null.This caused server crashes for queries that
required order by such a field and were executed without using a temporary
table.

The Item_func_set_user_var::register_field_in_read_map() now checks the
result_field to be not null.

ha_partition::update_create_info() just calls update_create_info
of a first partition, so only get the autoincrement maximum
of the first partition, so SHOW CREATE TABLE can show
small AUTO_INCREMENT parameters.
Fixed by implementing ha_partition::update_create_info() in a way
other handlers work.
HA_ARCHIVE:stats.auto_increment handling made consistent with other engines

Anti-patch. This patch undoes the previously pushed patch. It is 
null-merged in versions 5.1 and above since there the original 
patch is still desired.
