  Revise output of SHOW ENGINES.

  don't be confused if  new privilege - ENUM ('N','Y') - columns are added (mostly because of downgrade)
  don't expect NOT NULL fields to never contain a NULL :) - somebody may've changed table definition, or we may be reading the wrong column

   exception (it only applies to 4.0 and above)

  Fix the other typo, too. :-)

  Fix typo in comments.

The problem was that (for any storage engine), the created temporary table was not removed if CREATE SELECT failed (because
of a constraint violation for example). This was not consistent with the manual and with CREATE SELECT (no TEMPORARY).

BUG#4506 "mysqlbinlog --position --read-from-remote-server has wrong "# at" lines",
BUG#4553 "Multi-table DROP TABLE replicates improperly for nonexistent table" with a test file.
It was not possible to add a test for BUG#4506 as in the test suite we must use --short-form
which does not display the "# at" lines.

  if many plans have identical cost, which one will be used depends on how compiler optimizes floating-point calculations
  this fix adds repeatability to the optimizer
