Fixed BUG#15866: Thread stack limit insufficient for recursive call "fib(20)"

  Lowered the parameter to 10, and also renamed non-standard table names to t3.


mysql-test/r/sp.result:
  Updated results.
mysql-test/r/sp_trans.result:
  Updated results.
mysql-test/t/sp.test:
  Renamed fac, primes and fib tables to t3.
  Lowered fib() test parameter to 10 (20 hit the stack overrun check on some machines).
mysql-test/t/sp_trans.test:
  Added drop of t3 for safety. (Might be left from sp.test after certain test failures.)
