a8781d9d93 Update the fuzzcheck test module so that it avoids inserting text values 
that contain embedded NULs in the XSQL table.  Fix some legacy entries in
the test/fuzzdata8.db that had embedded NULs.  Add in new dbsqlfuzz cases
that have accumulated over on the dbsqlfuzz project for a while.

e8c4f03266 In the OP_Column opcode, if the cursor is marked NullRow (due to being the 
right table of a LEFT JOIN that does not match) and the cursor is the table
cursor for an OR-optimization with a covering index, then do not substitute
the covering index cursor, since the covering index cursor does not have
the NullRow flag set.  Ticket [aa4378693018aa99]
