Fix a long-standing bug where an initial sync would not respond to changes to the list of ignored users if there was an initial sync cached. (#15163)

Internally the push rules module uses a `pattern_type` property for `event_match`
conditions (and `related_event_match`) to mark the condition as matching the
current user's Matrix ID or localpart.

This is leaky to the Client-Server API where a user can successfully set a condition
which provides `pattern_type` instead of `pattern` (note that there's no benefit to
doing this -- the user can just use their own Matrix ID or localpart instead). When
serializing back to the client the `pattern_type` property is converted into a proper
`pattern`.

The following changes are made to avoid this:

* Separate the `KnownCondition::EventMatch` enum value into `EventMatch`
  and `EventMatchType`, each with their own expected properties. (Note that a
  similar change is made for `RelatedEventMatch`.)
* Make it such that the `pattern_type` variants serialize to the same condition kind,
  but cannot be deserialized (since they're only provided by base rules).
* As a final tweak, convert `user_id` vs. `user_localpart` values into an enum.

* Add documentation for caching in a module

* Changelog

* Formatting

* Wrap lines at a length that mdbook is happier with

* Typo fix

* Link to recent version of the API

In the longer term I'd like to see us generate markdown with Sphinx.

* Refer to public `cached` decorator

* Mark caching as being added in 1.74

Some of the underlying infrastructure was added in 1.69, but the
public-facing `cached` decorator was only added in 1.74. It is the
latter that I think we should be advertising.

* Update docs/modules/writing_a_module.md

* Fix a long-standing bug where search terms using combining accents
  would not match display names using precomposed accents and vice
  versa.

To fully take effect, the user directory must be rebuilt after this
change.

Previously if an autodiscovered oEmbed request failed (e.g. the
oEmbed endpoint is down or does not exist) then the entire URL
preview would fail. Instead we now return everything we can, even
if this additional request fails.

Ideally we would replace this with parsing of the Accept header
or something else, but for now just make Synapse spec compliant
by ignoring the unspecced parameter.

It does not seem that this is ever sent by a client, and even if it is
there's a reasonable fallback.

Previously the experimental configuration option referred to the wrong
MSC number.

To directly write to the open file, instead of writing to an
in-memory string first.

* Change `create_room` return type

* Don't return room alias from /createRoom

* Update other callsites

* Fix up mypy complaints

It looks like new_room_user_id is None iff new_room_id is None. It's a
shame we haven't expressed this in a way that mypy can understand.

* Upper-bound frozendict dependency

This is an ugly kludge to solve
https://github.com/matrix-org/synapse/issues/15109. It is not the most
friendly thing to do for downstream packagers (apologies), but we are a)
running low on time at the moment, and b) seeking to remove frozendict
anyway.

* Changelog

This is so installations will pull in the keyring package, allowing us
to update the expiry time of the `packages.matrix.org` repository.

* Update database_maintenance_tools.md

Included a blog post by Jackson Chen, which DID work when I followed it to perform Matrix Synapse Maintenance, versus the 2020 blog post by Victor Berger, which DID NOT work when performining maintenance.

* Update database_maintenance_tools.md

* Rephrasing

* Sort BOOLEAN_COLUMNS and APPEND_ONLY_TABLES

So I can see if a given table is present in logarithmic time, rather
than linear.

* Teach portdb about `un_partial_stated_event_streams`
