  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.

  dict_load_table(): Do not complain about mix_len != 0,
  because MySQL 3.23.4x left garbage in that column.

  Fix bad root element name in DOCTYPE.  Sheesh.

  dict_load_table(): Remove the check for row_format=compact for now,

  has not been zero for at least two customers.
