When fetching the state of a room over federation we receive the event
IDs of the state and auth chain. We then fetch those events that we
don't already have.
However, we used a function that recursively fetched any missing auth
events for the fetched events, which can lead to a lot of recursion if
the server is missing most of the auth chain. This work is entirely
pointless because would have queued up the missing events in the auth
chain to be fetched already.
Let's just diable the recursion, since it only gets called from one
place anyway.
Fixes#2181.
The basic premise is that, when we
fail to reject an invite via the remote server, we can generate our own
out-of-band leave event and persist it as an outlier, so that we have something
to send to the client.
* Starting with apt 1.6, https support has moved into the main package and apt-transport-https has become a transitional dummy package.

This table is no longer used, so we may as well stop populating it. Removing it
would prevent people rolling back to older releases of Synapse, so that can
happen in a future release.
* Fix spec compliance; tweaks without values are valid
(default to True, which is only concretely specified for
`highlight`, but it seems only reasonable to generalise)
* Changelog for 7766.
* Add documentation to `tweaks_for_actions`
May as well tidy up when I'm here.
* Add a test for `tweaks_for_actions`

The package was pinned to <0.8.0 without an obvious reasoning with
7ad1d7635
in https://github.com/matrix-org/synapse/pull/5636
while the version selection looks to just try to exclude an arbitrary
next minor version number that might introduce API breaking changes.
Selecting the next minor number might be a good conservative selection.
Downstream distributions already reported success patching out the version
requirements.
This also fixes the integration of upgraded packages into openSUSE packages,
e.g. for openSUSE Tumbleweed which already ships prometheus_client >= 0.8 .

The CI appears to use the latest version of isort, which is a problem when isort gets a major version bump. Rather than try to pin the version, I've done the necessary to make isort5 happy with synapse.
==============================
Synapse 1.16.0rc2 includes the security fixes released with Synapse 1.15.2.
Please see [below](https://github.com/matrix-org/synapse/blob/master/CHANGES.md#synapse-1152-2020-07-02) for more details.
Improved Documentation
----------------------
- Update postgres image in example `docker-compose.yaml` to tag `12-alpine`. ([\#7696](https://github.com/matrix-org/synapse/issues/7696))
Internal Changes
----------------
- Add some metrics for inbound and outbound federation latencies: `synapse_federation_server_pdu_process_time` and `synapse_event_processing_lag_by_event`. ([\#7771](https://github.com/matrix-org/synapse/issues/7771))

===========================
Due to the two security issues highlighted below, server administrators are
encouraged to update Synapse. We are not aware of these vulnerabilities being
exploited in the wild.
Security advisory
-----------------
* A malicious homeserver could force Synapse to reset the state in a room to a
small subset of the correct state. This affects all Synapse deployments which
federate with untrusted servers. ([96e9afe6](96e9afe625))
* HTML pages served via Synapse were vulnerable to clickjacking attacks. This
predominantly affects homeservers with single-sign-on enabled, but all server
administrators are encouraged to upgrade. ([ea26e9a9](ea26e9a98b))
