More `rows.Close()` and `rows.Err()` (#3262)
Looks like we missed some `rows.Close()`

Even though `rows.Err()` is mostly not necessary, we should be more
consistent in the DB layer.

Remove gmsl.HeaderedEvent (#3068)
Replaced with types.HeaderedEvent _for now_. In reality we want to move
them all to gmsl.Event and only use HeaderedEvent when we _need_ to
bundle the version/event ID with the event (seriailsation boundaries,
and even then only when we don't have the room version).

Optimize `/sync` and history visibility (#2961)
Should fix the following issues or make a lot less worse when using
Postgres:

The main issue behind #2911: The client gives up after a certain time,
causing a cascade of context errors, because the response couldn't be
built up fast enough. This mostly happens on accounts with many rooms,
due to the inefficient way we're getting recent events and current state

For #2777: The queries for getting the membership events for history
visibility were being executed for each room (I think 185?), resulting
in a whooping 2k queries for membership events. (Getting the
statesnapshot -> block nids -> actual wanted membership event)

Both should now be better by:
- Using a LATERAL join to get all recent events for all joined rooms in
one go (TODO: maybe do the same for room summary and current state etc)
- If we're lazy loading on initial syncs, we're now not getting the
whole current state, just to drop the majority of it because we're lazy
loading members - we add a filter to exclude membership events on the
first call to `CurrentState`.
- Using an optimized query to get the membership events needed to
calculate history visibility

Add `/_dendrite/admin/purgeRoom/{roomID}` (#2662)
This adds a new admin endpoint `/_dendrite/admin/purgeRoom/{roomID}`. It
completely erases all database entries for a given room ID.

The roomserver will start by clearing all data for that room and then
will generate an output event to notify downstream components (i.e. the
sync API and federation API) to do the same.

It does not currently clear media and it is currently not implemented
for SQLite since it relies on SQL array operations right now.

Don't limit `"state"` (#2849)
This is apparently some incorrect behaviour that we built as a result of
a spec bug (matrix-org/matrix-spec#1314) where we were applying a filter
to the `"state"` section of the `/sync` response incorrectly. The client
then has no way to know that the state was limited.

This PR removes the state limiting, which probably also helps #2842.

Get state deltas without filters (#2810)
This makes the following changes:
- get state deltas without the user supplied filter, so we can actually
"calculate" state transitions
- closes `stmt` when using SQLite
- Adds presence for users who newly joined a room, even if the syncing
user already knows about the presence status (should fix

Consistent `*sql.Tx` usage across sync API (#2744)

Fulltext implementation using Bleve (#2675)
Based on #2480

This actually indexes events based on their event type. They are removed
from the index if we receive a `m.room.redaction` event on the
`OutputRoomEvent` stream.
An admin endpoint is added to reindex all existing events.

Implement Push Notifications (#1842)
* Add Pushserver component with Pushers API

Co-authored-by: Dan Peleg <dan@globekeeper.com>

* Wire Pushserver component

Co-authored-by: Neil Alexander <neilalexander@users.noreply.github.com>

* Add PushGatewayClient.

The full event format is required for Sytest.

* Add a pushrules module.

* Change user API account creation to use the new pushrules module's defaults.

Introduces "scope" as required by client API, and some small field
tweaks to make some 61push Sytests pass.

* Add push rules query/put API in Pushserver.

This manipulates account data over User API, and fires sync messages
for changes. Those sync messages should, according to an existing TODO
in clientapi, be moved to userapi.

Forks clientapi/producers/syncapi.go to pushserver/ for later extension.

* Add clientapi routes for push rules to Pushserver.

A cleanup would be to move more of the name-splitting logic into
pushrules.go, to depollute routing.go.

* Output rooms.join.unread_notifications in /sync.

This is the read-side. Pushserver will be the write-side.

* Implement pushserver/storage for notifications.

* Use PushGatewayClient and the pushrules module in Pushserver's room consumer.

* Use one goroutine per user to avoid locking up the entire server for
  one bad push gateway.
* Split pushing by format.
* Send one device per push. Sytest does not support coalescing
  multiple devices into one push. Matches Synapse. Either we change
  Sytest, or remove the group-by-url-and-format logic.
* Write OutputNotificationData from push server. Sync API is already
  the consumer.

* Implement read receipt consumers in Pushserver.

Supports m.read and m.fully_read receipts.

* Add clientapi route for /unstable/notifications.

* Rename to UpsertPusher for clarity and handle pusher update

* Fix linter errors

* Ignore body.Close() error check

* Fix push server internal http wiring

* Add 40 newly passing 61push tests to whitelist

* Add next 12 newly passing 61push tests to whitelist

* Consume on the correct topic for the roomserver

* Don't panic, NAK instead

* Move push notifications into the User API

* Don't set null values since that apparently causes Element upsetti

* Also set omitempty on conditions

* Fix bug so that we don't override the push rules unnecessarily

* Tweak defaults

* Update defaults

* More tweaks

* Move `/notifications` onto `r0`/`v3` mux

* User API will consume events and read/fully read markers from the sync API with stream positions, instead of consuming directly

Add peer-to-peer support into Dendrite via libp2p and fetch (#880)
* Use a fork of pq which supports userCurrent on wasm

* Use sqlite3_js driver when running in JS

* Add cmd/dendritejs to pull in sqlite3_js driver for wasm only

* Update to latest go-sqlite-js version

* Replace prometheus with a stub. sigh

* Hard-code a config and don't use opentracing

* Latest go-sqlite3-js version

* Generate a key for now

* Listen for fetch traffic rather than HTTP

* Latest hacks for js

* libp2p support

* More libp2p

* Fork gjson to allow us to enforce auth checks as before

Previously, all events would come down redacted because the hash
checks would fail. They would fail because sjson.DeleteBytes didn't
remove keys not used for hashing. This didn't work because of a build
tag which included a file which no-oped the index returned.

See https://github.com/tidwall/gjson/issues/157

When it's resolved, let's go back to mainline.

* Use gjson@1.6.0 as it fixes https://github.com/tidwall/gjson/issues/157

* Use latest gomatrixserverlib for sig checks

* Fix a bug which could cause exclude_from_sync to not be set

Caused when sending events over federation.

* Use query variadic to make lookups actually work!

* Latest gomatrixserverlib

* Add notes on getting p2p up and running

Partly so I don't forget myself!

* refactor: Move p2p specific stuff to cmd/dendritejs

This is important or else the normal build of dendrite will fail
because the p2p libraries depend on syscall/js which doesn't work
on normal builds.

Also, clean up main.go to read a bit better.

* Update ho-http-js-libp2p to return errors from RoundTrip

* Add an LRU cache around the key DB

We actually need this for P2P because otherwise we can *segfault*
with things like: "runtime: unexpected return pc for runtime.handleEvent"
where the event is a `syscall/js` event, caused by spamming sql.js
caused by "Checking event signatures for 14 events of room state" which
hammers the key DB repeatedly in quick succession.

Using a cache fixes this, though the underlying cause is probably a bug
in the version of Go I'm on (1.13.7)

* breaking: Add Tracing.Enabled to toggle whether we do opentracing

Defaults to false, which is why this is a breaking change. We need
this flag because WASM builds cannot do opentracing.

* Start adding conditional builds for wasm to handle lib/pq

The general idea here is to have the wasm build have a `NewXXXDatabase`
that doesn't import any postgres package and hence we never import
`lib/pq`, which doesn't work under WASM (undefined `userCurrent`).

* Remove lib/pq for wasm for syncapi

* Add conditional building to remaining storage APIs

* Update build script to set env vars correctly for dendritejs

* sqlite bug fixes

* Docs

* Add a no-op main for dendritejs when not building under wasm

* Use the real prometheus, even for WASM

Instead, the dendrite-sw.js must mock out `process.pid` and
`fs.stat` - which must invoke the callback with an error (e.g `EINVAL`)
in order for it to work:

```
    global.process = {
        pid: 1,
    };
    global.fs.stat = function(path, cb) {
        cb({
            code: "EINVAL",
        });
    }
```

sqlite: fixes from sytest (#872)
* bugfix: fix panic on new invite events from sytest

I'm unsure why the previous code didn't work, but it's
clearer, quicker and easier to read the `LastInsertID()` way.
Previously, the code would panic as the SELECT would fail
to find the last inserted row ID.

* sqlite: Fix UNIQUE violations and close more cursors

- Add missing `defer rows.Close()`
- Do not have the state block NID as a PRIMARY KEY else it breaks for blocks
  with >1 state event in them. Instead, rejig the queries so we can still
  have monotonically increasing integers without using AUTOINCREMENT (which
  mandates PRIMARY KEY).

* sqlite: Add missing variadic function

* Use LastInsertId because empirically it works over the SELECT form (though I don't know why that is)

* sqlite: Fix invite table by using the global stream pos rather than one specific to invites

If we don't use the global, clients don't get notified about any invites
because the position is too low.

* linting: shadowing

* sqlite: do not use last rowid, we already know the stream pos!

* sqlite: Fix account data table in syncapi by commiting insert txns!

* sqlite: Fix failing federation invite

Was failing with 'database is locked' due to multiple write txns
being taken out.

* sqlite: Ensure we return exactly the number of events found in the database

Previously we would return exactly the number of *requested* events, which
meant that several zero-initialised events would bubble through the system,
failing at JSON serialisation time.

* sqlite: let's just ignore the problem for now....
