* Allow membership event to unban user

Signed-off-by: Aaron Raimist <aaron@raim.ist>

To avoid duplicating it between a few tests.

Instead of proxying through the magic getter of the RootConfig
object. This should be more performant (and is more explicit).

By copying the `room_type` field of the create event and
migrating any non-empty `m.space.child` events to the
new room that is created.

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 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)

* Add some tests to characterise the problem

Some failing. Current states:

  RoomsMemberListTestCase
test_get_member_list ...
[OK]
test_get_member_list_mixed_memberships ...
[OK]
test_get_member_list_no_permission ...
[OK]
test_get_member_list_no_permission_former_member ...

[FAIL]
test_get_member_list_no_room ...
[OK]
test_get_member_list_no_permission_with_at_token ...
[FAIL]

* Correct the tests

* Check user is/was member before divulging room membership

* Pull out only the 1 membership event we want.

* Update tests/rest/client/v1/test_rooms.py

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.

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.

And ensure that the file is checked via mypy.

This is mostly useful in case the server offers TLS, but doesn't present a valid certificate.

Fixes a bug introduced in rc1 that would cause Synapse to 400 on read receipts requests with empty bodies.

Broken in #10413

Implementation of matrix-org/matrix-doc#2285

* Fix no-access-token bug in deactivation tests
* Support MSC2033: Device ID on whoami
* Test for appservices too

MSC: https://github.com/matrix-org/matrix-doc/pull/2033

The MSC has passed FCP, which means stable endpoints can be used.

Improves type hints for:

* parse_{boolean,integer}
* parse_{boolean,integer}_from_args
* parse_json_{value,object}_from_request

And fixes any incorrect calls that resulted from unknown types.
