Author: Neil Alexander <neilalexander@users.noreply.github.com>

Support bare Yggdrasil sessions with encrypted QUIC
* Add a bit more logging to the fedsender
* bugfix: continue sending PDUs if ones are added whilst sending another PDU
Without this, the queue goes back to sleep on `<-oq.notifyPDUs` which won't
fire because `pendingPDUs` is already > 0. This should fix a flakey sytest.
* Break if no txn is sent
* WIP syncapi work
* More debugging
* Bump GMSL version to pull in working Event.Redact
* Remove logging
* Make redactions work on v3+
* Fix more tests
* 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
* Don't return null to public directory request
* Initial support for finding public rooms in Yggdrasil demo (incomplete)
* Increase QUIC idle time to 15 minutes
* Initial QUIC work
* Update Yggdrasil demo
* Make sure that the federation sender knows how many pending events are in the database when the worker starts
* QUIC tunables
* pprof
* Don't spin
* Set build info for Yggdrasil
* 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
* Return remote errors from FS.PerformJoin
Follows the same pattern as PerformJoin on roomserver (no error return).

* Initial cut for backfilling
The syncserver now asks the roomserver via QueryBackfill (which already
existed to *handle* backfill requests) which then makes federation requests
via gomatrixserverlib.RequestBackfill.
Currently, tests fail on subsequent /messages requests because we don't know
which servers are in the room, because we are unable to get state snapshots
from a backfilled event because that code doesn't exist yet.

Author: Ben B <benne@klimlive.de>
Date: Fri Apr 3 12:40:50 2020 +0200
use custom http client instead of the http DefaultClient (#823)
This commit replaces the default client from the http lib with a custom one.
The previously used default client doesn't come with a timeout. This could cause
unwanted locks.
That solution chosen here creates a http client in the base component dendrite
with a constant timeout of 30 seconds. If it should be necessary to overwrite
this, we could include the timeout in the dendrite configuration.
Here it would be a good idea to extend the type "Address" by a timeout and
create an http client for each service.
Closes#820
