Enables MSC3925 support by default, which:
* Includes the full edit event in the bundled aggregations of an
edited event.
* Stops modifying the original event's content to return the new
content from the edit event.
This is a backwards-incompatible change that is considered to be
"correct" by the spec.
AbstractStreamIdTracker (now) has only a single sub-class: AbstractStreamIdGenerator,
combine them to simplify some code and remove any direct references to
AbstractStreamIdTracker.
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.
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

* 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.

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

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.

* 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.

Previously, when creating a join event in /make_join, we would decide
whether to include additional fields to satisfy restricted room checks
based on the current state of the room. Then, when building the event,
we would capture the forward extremities of the room to use as prev
events.
This is subject to race conditions. For example, when leaving and
rejoining a room, the following sequence of events leads to a misleading
403 response:
1. /make_join reads the current state of the room and sees that the user
is still in the room. It decides to omit the field required for
restricted room joins.
2. The leave event is persisted and the room's forward extremities are
updated.
3. /make_join builds the event, using the post-leave forward extremities.
The event then fails the restricted room checks.
To mitigate the race, we move the read of the forward extremities closer
to the read of the current state. Ideally, we would compute the state
based off the chosen prev events, but that can involve state resolution,
which is expensive.

I tried to workaround the ignores but found it too much trouble.
I think the corresponding issue is
https://github.com/python/mypy/issues/12909. The mypy repo has a PR
claiming to fix this (https://github.com/python/mypy/pull/14677) which
might mean this gets resolved soon?
* Better annotation for INTERACTIVE_AUTH_CHECKERS
* Drive-by AUTH_TYPE annotation, to remove an ignore
This replaces the specific `is_room_mention` push rule condition
used in MSC3952 with the generic `exact_event_match` push rule
condition from MSC3758.
No functionality changes due to this.
Previously we would give up upon receiving a 404 from the first server,
instead of trying the rest of the servers in the list.

* Fix order of partial state tables when purging
`partial_state_rooms` has an FK on `events` pointing to the join event we
get from `/send_join`, so we must delete from that table before deleting
from `events`.
**NB:** It would be nice to cancel any resync processes for the room
being purged. We do not do this at present. To do so reliably we'd need
an internal HTTP "replication" endpoint, because the worker doing the
resync process may be different to that handling the purge request.
The first time the resync process tries to write data after the deletion
it will fail because we have deleted necessary data e.g. auth
events. AFAICS it will not retry the resync, so the only downside to
not cancelling the resync is a scary-looking traceback.
(This is presumably extremely race-sensitive.)

...when lazy loading of members is not enabled. It's weird to notify
a client that another user's device list has changed when the client
doesn't think that they share a room.
Note that when a room is un-partial stated, device list updates are
emitted for every member in that room over /sync.
