Fix for this bug and additional improvements/fixes
In detail:
- Remove unicode attribute from several columns
  (unicode properties were nowhere needed/tested)
  of the table tb3
  -> The runnability of these tests depends no more on
     the availibility of some optional collations.
- Use a table tb3 with the same layout for all
  engines to be tested and unify the engine name
  within the protocols.
  -> <engine>_trig_<abc>.result have the same content
- Do not load data into tb3 if these rows have no
  impact on result sets
- Add tests for NDB (they exist already in 5.1)
- "--replace_result" at various places because
  NDB variants of tests failed with "random" row
  order in results
  This fixes a till now unknown weakness within the
  funcs_1 NDB tests existing in 5.1 and 6.0
- Fix the expected result of ndb_trig_1011ext
  which suffered from Bug 32656
  + disable this test
- funcs_1 could be executed with the mysql-test-run.pl
  option "--reorder", which saves some runtime by
  optimizing server restarts.
  Runtimes on tmpfs (one attempt only):
  with    reorder 132 seconds
  without reorder 183 seconds
- Adjust two "check" statements within func_misc.test
  which were incorrect (We had one run with result set
  difference though the server worked good.)
- minor fixes in comments
