Fix event chain bg update. (#9118) 
We passed in a graph to `sorted_topologically` which didn't have an
entry for each node (as we dropped nodes with no edges).

Split OidcProvider out of OidcHandler (#9107) 
The idea here is that we will have an instance of OidcProvider for each
configured IdP, with OidcHandler just doing the marshalling of them.

For now it's still hardcoded with a single provider.

Fix wrong arguments being passed to BlacklistingAgentWrapper (#9098) 
A reactor was being passed instead of a whitelist for the BlacklistingAgentWrapper
used by the WellyKnownResolver. This coulld cause exceptions when attempting to
connect to IP addresses that are blacklisted, but in reality this did not have any
observable affect since this code is not used for IP literals.

5310808d3b Give the user a better error when they present bad SSO creds 
If a user tries to do UI Auth via SSO, but uses the wrong account on the SSO
IdP, try to give them a better error.

Previously, the UIA would claim to be successful, but then the operation in
question would simply fail with "auth fail". Instead, serve up an error page
which explains the failure.

Add basic domain validation for DomainSpecificString.is_valid. (#9071) 
This checks that the domain given to `DomainSpecificString.is_valid` (e.g.
`UserID`, `RoomAlias`, etc.) is of a valid form. Previously some validation
was done on the localpart (e.g. the sigil), but not the domain portion.

UI Auth via SSO: redirect the user to an appropriate SSO. (#9081) 
If we have integrations with multiple identity providers, when the user does a UI Auth, we need to redirect them to the right one.

There are a few steps to this. First of all we actually need to store the userid of the user we are trying to validate in the UIA session, since the /auth/sso/fallback/web request is unauthenticated.

Then, once we get the /auth/sso/fallback/web request, we can fish the user id out of the session, and use it to look up the external id mappings, and hence pick an SSO provider for them.

Remove SynapseRequest.get_user_agent (#9069) 
SynapseRequest is in danger of becoming a bit of a dumping-ground for "useful stuff relating to Requests",
which isn't really its intention (its purpose is to override render, finished and connectionLost to set up the 
LoggingContext and write the right entries to the request log).

Putting utility functions inside SynapseRequest means that lots of our code ends up requiring a
SynapseRequest when there is nothing synapse-specific about the Request at all, and any old
twisted.web.iweb.IRequest will do. This increases code coupling and makes testing more difficult.

In short: move get_user_agent out to a utility function.

0312266ee3 Synapse 1.25.0rc1 (2021-01-06) 
==============================
 
 Removal warning
 ---------------
 
 The old [Purge Room API](https://github.com/matrix-org/synapse/tree/master/docs/admin_api/purge_room.md)
 and [Shutdown Room API](https://github.com/matrix-org/synapse/tree/master/docs/admin_api/shutdown_room.md)
 are deprecated and will be removed in a future release. They will be replaced by the
 [Delete Room API](https://github.com/matrix-org/synapse/tree/master/docs/admin_api/rooms.md#delete-room-api).
 
 `POST /_synapse/admin/v1/rooms/<room_id>/delete` replaces `POST /_synapse/admin/v1/purge_room` and
 `POST /_synapse/admin/v1/shutdown_room/<room_id>`.

Merge tag 'v1.25.0rc1' into develop

Synapse 1.25.0rc1 (2021-01-06)
==============================

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

The old [Purge Room API](https://github.com/matrix-org/synapse/tree/master/docs/admin_api/purge_room.md)
and [Shutdown Room API](https://github.com/matrix-org/synapse/tree/master/docs/admin_api/shutdown_room.md)
are deprecated and will be removed in a future release. They will be replaced by the
[Delete Room API](https://github.com/matrix-org/synapse/tree/master/docs/admin_api/rooms.md#delete-room-api).

`POST /_synapse/admin/v1/rooms/<room_id>/delete` replaces `POST /_synapse/admin/v1/purge_room` and
`POST /_synapse/admin/v1/shutdown_room/<room_id>`.
