Remove unspecced and buggy `PUT` method on the unstable `/rooms/<room_id>/batch_send` endpoint. (#15199)

Experimental MSC3890 Implementation: Fix deleting account data when using an account data writer worker (#14869)

* Complement: Spell out when config isn't generated

* Changelog

Update intentional mentions (MSC3952) to depend on `exact_event_property_contains` (MSC3966). (#15051)

This replaces the specific `is_user_mention` push rule condition
used in MSC3952 with the generic `exact_event_property_contains`
push rule condition from MSC3966.

It turns out that no clients rely on server-side aggregation of `m.annotation`
relationships: it's just not very useful as currently implemented.

It's also non-trivial to calculate.

I want to remove it from MSC2677, so to keep the implementation in line, let's
remove it here.

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

This only affects deployments using workers.

* Fix a long-standing bug where non-ASCII characters in search terms,
  including accented letters, would not match characters in a different
  case.
* 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.

Fixes #14630.

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.
