1e25d20cca Update sqlite3changeset_apply_v2() so that it handles no-op UPDATE changes (UPDATE changes that modify no columns). This fixes a regression introduced by [e4ccfac09b]. Also modify sqlite3rebaser_rebase() so that it does not output changesets containing such UPDATEs.

f824b41e64 Break out the Cte object from the With object. This will make it simpler 
to add new kinds of Cte objects (ex: DML statements) and/or MATERIALIZED
keywords in the future.  It brings trunk into closer alignment with the
experimental as-materialize branch.
