  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.

  bug#4914 added --help and usage information

    preserve backward compatibility
