Subject: [PATCH] branches/zip: row_sel_get_clust_rec_for_mysql(): Similar to
 the function row_sel_get_clust_rec(), return if a previous version of the
 clustered index record does not exist in the read view.  This bug was made
 and found by Heikki.  It was harmless as long as the clustered index record
 contained a long enough local prefix of externally stored columns, to allow
 secondary index records to be built without fetching BLOBs.

InnoDB transactions should never look at a clustered index record whose
transaction identifier (DB_TRX_ID) is not visible in the transaction's
read view.
