# Description of Changes

Updates views atomically on commit, but before downgrading to a
read-only transaction for subscription evaluation.

What this patch does:
1. Renames `ViewId` to `ViewFnPtr`
2. Renames `ViewDatabaseId` to `ViewId`
3. Removes the `module_rx` module watcher from the subscription manager
4. Refactors read sets to only track table scans (index key tracking
will be added later)
5. Drops read sets and removes rows from `st_view_sub` when dropping a
view in an auto-migrate
6. Re-evaluates and updates views (`call_views_with_tx`) from
`call_reducer_with_tx` for any view whose read set overlaps with the
reducer's write set
7. Does the same for sql dml

# API and ABI breaking changes
