This adds the format to the request arguments / URL to
ensure that JSON data is returned (which is all that
Synapse supports).

This also adds additional error checking / filtering to the
configuration file to ignore XML-only providers.

This avoids breaking the entire endpoint if a room with
an unsupported room version is encountered.

This updates the ordering of the returned events from the spaces
summary API to that defined in MSC2946 (which updates MSC1772).

Previously a step was skipped causing ordering to be inconsistent with
clients.

 - Fill in creator whenever we insert into the rooms table
 - Add background update to backfill any missing creator values

Judging by the template, this was intended ages ago, but we never
actually passed an avatar URL to the template. So let's provide one.

Closes #1546.

This adds configuration options (under an `oembed` section) to
configure which URLs are matched to use oEmbed for URL
previews.

These were broken in an incorrect merge of GHSA-jj53-8fmw-f2w2 (cb35df94)

Turns out that the functionality added in #10546 to skip TLS was incompatible
with older Twisted versions, so we need to be a bit more inventive.

Also, add a test to (hopefully) not break this in future. Sadly, testing TLS is
really hard.

Fixes: #9544

The idea here is to take anything to do with incoming events and move it out to a separate handler, as a way of making FederationHandler smaller.

When a user deletes an email from their account it will
now also remove all pushers for that email and that user
(even if these pushers were created by a different client)

This is part of my GSoC project implementing [MSC3231](https://github.com/matrix-org/matrix-doc/pull/3231).

By replacing duplicated code with parameterized tests and
avoiding unnecessary dumping of JSON data.

Merged before approval; these comments from @clokep on that PR.

* Validate device_keys for C-S /keys/query requests

Closes #10354

A small, not particularly critical fix. I'm interested in seeing if we
can find a more systematic approach though. #8445 is the place for any discussion.

Here we split on_receive_pdu into two functions (on_receive_pdu and process_pulled_event), rather than having both cases in the same method. There's a tiny bit of overlap, but not that much.

A user will still see this room if it is in a local cache, but it will
not reappear if clearing the cache and reloading.

Instead of using namedtuples. This helps with asserting type hints
and code completion.

Allow using several directories in read_templates.

This adds a new API GET /_synapse/admin/v1/username_available?username=foo to check if a username is available. It is the counterpart to https://matrix.org/docs/spec/client_server/r0.6.0#get-matrix-client-r0-register-available, except that it works even if registration is disabled.
