correct top_level_item for XOR

item_cmpfunc.h:
  A wrong not_null_tables method for Item_cond_xor
  caused a conversion of a left join into an inner join
  that was not valid.

  Correction after manual merge.

  Better ibbackup message
  Add a message explaining why we do a 'crash recovery' after an ibbackup restore; suggested by Tim Smith

The reported problems were due to two completely unrelated omissions.
1) The file sort procedure didn't correctly create the sort key in
   make_sortkey when the sortkey was an unsigned integer.
2) The name resolution procedure for column references inside a HAVING
   clause did not propagate the unsigned_flag of the resolved references.
This patch corrects both problems.
