Merge Bug #54679 fix from mysql-5.1-innodb:

------------------------------------------------------------ revno: 3523 revision-id: marko.makela@oracle.com-20100624104620-pklunowaigv7quu9 parent: jimmy.yang@oracle.com-20100624021010-oh2hnp8e1xbaax6u committer: Marko Mäkelä <marko.makela@oracle.com> branch nick: 5.1-innodb timestamp: Thu 2010-06-24 13:46:20 +0300 message: Bug#54679: alter table causes compressed row_format to revert to compact ha_innobase::create(): Add the local variable row_type = form->s->row_type. Adjust it to ROW_TYPE_COMPRESSED when ROW_FORMAT is not specified or inherited but KEY_BLOCK_SIZE is. Observe the inherited ROW_FORMAT even when it is not explicitly specified. innodb_bug54679.test: New test, to test the bug and to ensure that there are no regressions. (The only difference in the test result without the patch applied is that the first ALTER TABLE changes ROW_FORMAT to Compact.)
