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.

418454c63f For SQLITE_ENABLE_PREUPDATE_HOOK builds, disable the optimization for a
REPLACE command on a WITHOUT ROWID table with no indexes, triggers or foreign
key constraints that causes SQLite to clobber any existing row without
separately checking for it. This optimization causes SQLite to omit the
expected pre-update-hook callbacks.
