* db migration: fix#1844 and add additional assertions
- Migration scripts will now check to see if there are any unconverted
snapshot IDs and fail the migration if there are any. This should
prevent people from getting a corrupt database in the event the root
cause is still unknown.
- Add an ORDER BY clause when doing batch queries in the postgres
migration. LIMIT and OFFSET without ORDER BY are undefined and must
not be relied upon to produce a deterministic ordering (e.g row order).
See https://www.postgresql.org/docs/current/queries-limit.html

* WIP Event rejection
* Still send back errors for rejected events
Instead, discard them at the federationapi /send layer rather than
re-implementing checks at the clientapi/PerformJoin layer.
* Implement rejected events
Critically, rejected events CAN cause state resolution to happen
as it can merge forks in the DAG. This is fine, _provided_ we
do not add the rejected event when performing state resolution,
which is what this PR does. It also fixes the error handling
when NotAllowed happens, as we were checking too early and needlessly
handling NotAllowed in more than one place.
* Update test to match reality
* Modify InputRoomEvents to no longer return an error
Errors do not serialise across HTTP boundaries in polylith mode,
so instead set fields on the InputRoomEventsResponse. Add `Err()`
function to make the API shape basically the same.
* Remove redundant returns; linting
* Update blacklist
* Move currentstateserver API to roomserver
Stub out DB functions for now, nothing uses the roomserver version yet.
* Allow it to startup
* Implement some current-state-server storage interface functions
* Add missing package

* Tweak federation API test
* Set MaxOpenConnections/MaxIdleConnections to previous values
* Update generate-config
* Emit redacted_event from the roomserver when redactions are validated
- Consume them in the currentstateserver and act accordingly.
- Add integration test for the roomserver to check that injecting
`m.room.redaction` events result in `redacted_event` being emitted.
* Linting
* Ignore events that redact themselves
* Implement core redaction logic
- Add a new `redactions_table.go` which tracks the mapping of
the redaction event ID and the redacted event ID
- Mark redactions as 'validated' when we have both events.
- When redactions are validated, add `unsigned.redacted_because`
and modify the `eventJSON` accordingly.
Note: We currently do NOT redact the event content - it's gated
behind a feature flag - until we have tested redactions a bit more.
* Linting
* Use content_value instead of membership
* Fix build
* Replace publicroomsapi with a combination of clientapi/roomserver/currentstateserver
- All public rooms paths are now handled by clientapi
- Requests to (un)publish rooms are sent to the roomserver via `PerformPublish`
which are stored in a new `published_table.go`
- Requests for public rooms are handled in clientapi by:
* Fetch all room IDs which are published using `QueryPublishedRooms` on the roomserver.
* Apply pagination parameters to the slice.
* Do a `QueryBulkStateContent` request to the currentstateserver to pull out
required state event *content* (not entire events).
* Aggregate and return the chunk.
Mostly but not fully implemented (DB queries on currentstateserver are missing)
* Fix pq query
* Make postgres work
* Make sqlite work
* Fix tests
* Unbreak pagination tests
* Linting
* Move Updater structs to shared and use it for postgres
* Add constructors for NewXXXUpdater and a useTxns flag
In sqlite, we set useTxns=false and comment why.
* Handle nil txn
* Handle nil in transaction
* Missed one
* Close the txn at the right time
* Don't close the transaction as we reuse it between calls
* Limit database connections (#564)
- Add new options to the config file database:
max_open_conns: 100
max_idle_conns: 2
conn_max_lifetime: -1
- Implement connection parameter setup on the *DB (database/sql) in internal/sqlutil/trace.go:Open()
- Propagate the values in the form of DbProperties interface via all the
Open() and NewDatabase() functions

* Always defer *sql.Rows.Close and consult with Err
database/sql.Rows.Next() makes sure to call Close only after exhausting
result rows which would NOT happen when returning early from a bad Scan.
Close being idempotent makes it a great candidate to get always deferred
regardless of what happens later on the result set.
This change also makes sure call Err() after exhausting Next() and
propagate non-nil results from it as the documentation advises.
