Add experimental support for sharding event persister. Again. (#8294) 
This is *not* ready for production yet. Caveats:

1. We should write some tests...
2. The stream token that we use for events can get stalled at the minimum position of all writers. This means that new events may not be processed and e.g. sent down sync streams if a writer isn't writing or is slow.

Use TLSv1.2 for fake servers in tests (#8208) 
Some Linux distros have begun disabling TLSv1.0 and TLSv1.1 by default
for security reasons, for example in Fedora 33 onwards:

https://fedoraproject.org/wiki/Changes/StrongCryptoSettings2

Use TLSv1.2 for the fake TLS servers created in the test suite, to avoid
failures due to OpenSSL disallowing TLSv1.0:

Clean up Notifier.on_new_room_event code path (#8288) 
The idea here is that we pass the `max_stream_id` to everything, and only use the stream ID of the particular event to figure out *when* the max stream position has caught up to the event and we can notify people about it.

This is to maintain the distinction between the position of an item in the stream (i.e. event A has stream ID 513) and a token that can be used to partition the stream (i.e. give me all events after stream ID 352). This distinction becomes important when the tokens are more complicated than a single number, which they will be once we start tracking the position of multiple writers in the tokens.

The valid operations here are:

1. Is a position before or after a token
2. Fetching all events between two tokens
3. Merging multiple tokens to get the "max", i.e. `C = max(A, B)` means that for all positions P where P is before A *or* before B, then P is before C.

Future PR will change the token type to a dedicated type.

Show a confirmation page during user password reset (#8004) 
This PR adds a confirmation step to resetting your user password between clicking the link in your email and your password actually being reset.

This is to better align our password reset flow with the industry standard of requiring a confirmation from the user after email validation.

Fixup pusher pool notifications (#8287) 
`pusher_pool.on_new_notifications` expected a min and max stream ID, however that was not what we were passing in. Instead, let's just pass it the current max stream ID and have it track the last stream ID it got passed.

I believe that it mostly worked as we called the function for every event. However, it would break for events that got persisted out of order, i.e, that were persisted but the max stream ID wasn't incremented as not all preceding events had finished persisting, and push for that event would be delayed until another event got pushed to the effected users.

Include method in thumbnail media name (#7124) 
This fixes an issue where different methods (crop/scale) overwrite each other.

This first tries the new path. If that fails and we are looking for a
remote thumbnail, it tries the old path. If that still isn't found, it
continues as normal.

This should probably be removed in the future, after some of the newer
thumbnails were generated with the new path on most deployments. Then
the overhead should be minimal if the other thumbnails need to be
regenerated.

Add a config option for validating 'next_link' parameters against a domain whitelist (#8275) 
This is a config option ported over from DINUM's Sydent: https://github.com/matrix-org/sydent/pull/285

They've switched to validating 3PIDs via Synapse rather than Sydent, and would like to retain this functionality.

This original purpose for this change is phishing prevention. This solution could also potentially be replaced by a similar one to https://github.com/matrix-org/synapse/pull/8004, but across all `*/submit_token` endpoint.

This option may still be useful to enterprise even with that safeguard in place though, if they want to be absolutely sure that their employees don't follow links to other domains.

Richard van der Hoff cca03dbec8 Synapse 1.20.0rc1 (2020-09-08) 
==============================
 
 Removal warning
 ---------------
 
 Some older clients used a [disallowed character](https://matrix.org/docs/spec/client_server/r0.6.1#post-matrix-client-r0-register-email-requesttoken) (`:`) in the `client_secret` parameter of various endpoints. The incorrect behaviour was allowed for backwards compatibility, but is now being removed from Synapse as most users have updated their client. Further context can be found at [\#6766](https://github.com/matrix-org/synapse/issues/6766).
 
 Features
 --------
 
 - Add an endpoint to query your shared rooms with another user as an implementation of [MSC2666](https://github.com/matrix-org/matrix-doc/pull/2666). ([\#7785](https://github.com/matrix-org/synapse/issues/7785))
 - Iteratively encode JSON to avoid blocking the reactor. ([\#8013](https://github.com/matrix-org/synapse/issues/8013), [\#8116](https://github.com/matrix-org/synapse/issues/8116))

Merge tag 'v1.20.0rc1' into develop

Synapse 1.20.0rc1 (2020-09-08)
==============================

Removal warning
---------------

Some older clients used a [disallowed character](https://matrix.org/docs/spec/client_server/r0.6.1#post-matrix-client-r0-register-email-requesttoken) (`:`) in the `client_secret` parameter of various endpoints. The incorrect behaviour was allowed for backwards compatibility, but is now being removed from Synapse as most users have updated their client. Further context can be found at [\#6766](https://github.com/matrix-org/synapse/issues/6766).

Features
--------

- Add an endpoint to query your shared rooms with another user as an implementation of [MSC2666](https://github.com/matrix-org/matrix-doc/pull/2666). ([\#7785](https://github.com/matrix-org/synapse/issues/7785))
- Iteratively encode JSON to avoid blocking the reactor. ([\#8013](https://github.com/matrix-org/synapse/issues/8013), [\#8116](https://github.com/matrix-org/synapse/issues/8116))
- Add support for shadow-banning users (ignoring any message send requests). ([\#8034](https://github.com/matrix-org/synapse/issues/8034), [\#8092](https://github.com/matrix-org/synapse/issues/8092), [\#8095](https://github.com/matrix-org/synapse/issues/8095), [\#8142](https://github.com/matrix-org/synapse/issues/8142), [\#8152](https://github.com/matrix-org/synapse/issues/8152), [\#8157](https://github.com/matrix-org/synapse/issues/8157), [\#8158](https://github.com/matrix-org/synapse/issues/8158), [\#8176](https://github.com/matrix-org/synapse/issues/8176))
- Use the default template file when its equivalent is not found in a custom template directory. ([\#8037](https://github.com/matrix-org/synapse/issues/8037), [\#8107](https://github.com/matrix-org/synapse/issues/8107), [\#8252](https://github.com/matrix-org/synapse/issues/8252))
- Add unread messages count to sync responses, as specified in [MSC2654](https://github.com/matrix-org/matrix-doc/pull/2654). ([\#8059](https://github.com/matrix-org/synapse/issues/8059), [\#8254](https://github.com/matrix-org/synapse/issues/8254), [\#8270](https://github.com/matrix-org/synapse/issues/8270), [\#8274](https://github.com/matrix-org/synapse/issues/8274))
- Optimise `/federation/v1/user/devices/` API by only returning devices with encryption keys. ([\#8198](https://github.com/matrix-org/synapse/issues/8198))
