BUG # 17631 SHOW TABLE STATUS reports wrong engine

mysql-test/r/partition.result:
  results block for bug # 17631
mysql-test/t/partition.test:
  test block for bug #17631
sql/ha_partition.cc:
  move table_type func to .cc file and return table_type from
  the first handler.  This is acceptable since we know we have
  at least one handler and we currently do not support multiple
  engine types.  Later, we'll need to extend this to return
  some type of delimited list
sql/ha_partition.h:
  removed inline version of this function
sql/sql_show.cc:
  if the table is partitioned, we add the term "partitioned" to the 
  create options.  We make sure we are using the partitioned 
  handlerton before we do this.  When we support more native partition
  handlers then this will need to change.
