resolve_const_item() assumed to be not called for Item_row items. For
ensuring that DBUG_ASSERT(0) was set there.

This patch adds section for Item_row items. If it can it recursively calls
resolve_const_item() for each item the Item_row contains. If any of the
contained items is null then whole Item_row substitued by Item_null. Otherwise
it just returns.

  Fix bug#13356 resolve_const_item() wasn't able to handle Item_row items.
  
  Added section to resolve_const_item() for Item_row items. If it can it
  recursively calls resolve_const_item() for each item the Item_row contains. If
  any of the contained items is null then Item_row is substituted by Item_null.
  Otherwise it just returns.
  Comment moved closer to function it belongs to.

  Manual merge

The problem was an ab-use of last_rkey_length.
Formerly we saved the packed key length (of the search key)
in this element. But in certain cases it got replaced by 
the (packed) result key length.
Now we use a new element of MI_INFO to save the packed key 
length of the search key.

thd->allow_sum_func was left 'true' after previous statement thus allowing
sum funcs to be present in conditions.

thd->allow_sum_func should be set to 0 for each query and each prepared
statement reinitialization. This is done in lex_start() and 
reset_stmt_for_execute().
