Fix for BUG#37005 "Maria: ALTER TABLE TRANSACTIONAL=0 leaves table transactional inside Maria" 

mysql-test/r/maria-page-checksum.result:
  result for new test portion. Without the code fix, you would see a wrong "yes" or "no" in the "Crashsafe" line
  for iterations 2,9,14.
mysql-test/t/maria-page-checksum.test:
  Adding test for BUG#37005 "Maria: ALTER TABLE TRANSACTIONAL=0 leaves table transactional inside Maria"
sql/sql_table.cc:
  In ALTER TABLE, we already rebuilt the table entirely if the DEFAULT CHARSET, ROW_FORMAT or PAGE_CHECKSUM
  clauses were used; we have to do the same if the TRANSACTIONAL clause is used, because it affects
  the table inside the engine (for example, Maria makes shorter rows in non-transactional tables).
  Not doing so led to the BUG#37005, where ALTER TABLE TRANSACTIONAL=0 sometimes left the table
  transactional into Maria though not in the frm.
