Temporary tables are not written to disk by DDL operations. This makes
DDL much faster (useful for tests), but tables are lost after system
restart.

New commit, since this feature will not be available in 5.1.

Fixed "discover" in the handler API.

Fixed problem where handlerton was not zero'ed. I need to look around, I suspect this problem is more widespread.

should work in Prepared Statements. Post-review changeset.

Problem: There are some commands which are avaiable to be executed in SP
         but cannot be prepared. This patch fixes this and makes it possible
         prepare these statements.

Changes: The commands later are made available in PS. RESET has been forbidden
         in SF/Trigger.

Solution: All current server commands where checked and those missing (see later)
          we added. Tests for all of the commands with repeated executions were
          added - testing with SP, SF and PS.

GROUP BY/DISTINCT pruning optimization must be done before ORDER BY 
optimization because ORDER BY may be removed when GROUP BY/DISTINCT
sorts as a side effect, e.g. in 
  SELECT DISTINCT <non-key-col>,<pk> FROM t1
  ORDER BY <non-key-col> DISTINCT
must be removed before ORDER BY as if done the other way around
it will remove both.

  Fix so that expand_check2 is only run per fragment,
  as restore now works 1 fragment at a time (again)
