3f1e9e00e6 When flattening a query, make sure iTable attribute of TK_IF_NULL_ROW

07d0f15e93 Fix incompatibilities between the "sqldiff --changeset" command and the 
sessions module. Specifically, allow sessions to process changesets containing
tables with zero operations on them and have sqldiff output the expected
output for tables with multi-column primary keys.

21766c0c16 Fix a case where NULL was being passed to memcmp() following an OOM. This is

this case, but it was causing a santizer complaint.
