* 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.

* 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.)

Fixes#12801.
Complement tests are at
https://github.com/matrix-org/complement/pull/567.
Avoid blocking on full state when handling a subsequent join into a
partial state room.
Also always perform a remote join into partial state rooms, since we do
not know whether the joining user has been banned and want to avoid
leaking history to banned users.

It's important that collections returned from `@cached` methods are not
modified, otherwise future retrievals from the cache will return the
modified collection.
This applies to the return values from `@cached` methods and the values
inside the dictionaries returned by `@cachedList` methods. It's not
necessary for the dictionaries returned by `@cachedList` methods
themselves to be read-only.

The per-room account data is no longer unconditionally
fetched, even if all rooms will be filtered out.
Global account data will not be fetched if it will all be
filtered out.
The previous version of the code could mutate a cached value,
but only if the input requested all devices of a user *and* a specific
device.
To avoid this nonsensical situation we no longer fetch a specific
device ID if all of a user's devices are returned.
This adds an `event_stream_ordering` column to `current_state_events`,
`local_current_membership` and `room_memberships`. Each of these tables
is regularly joined with the `events` table to get the stream ordering
and denormalising this into each table will yield significant query
performance improvements once used. Includes a background job to
populate these values from the `events` table.
Same idea as https://github.com/matrix-org/synapse/pull/13703.

* Accept a Sequence of events in synapse.appservice
This avoids some casts/ignores in the tests I'm about to fixup. It seems
that `List[Mock]` is not a subtype of `List[EventBase]`, but
`Sequence[Mock]` is a subtype of `Sequence[EventBase]`. So presumably
`Mock` is considered a subtype of anything, much like `Any`.

Copy the suppress_edits push rule from Beeper to implement MSC3958.
9415a1284b/rust/src/push/base_rules.rs (L98-L114)
Ensure that the list of servers in a partial state room always contains
the server we joined off.
Also refactor `get_partial_state_servers_at_join` to return `None` when
the given room is no longer partial stated, to explicitly indicate when
the room has partial state. Otherwise it's not clear whether an empty
list means that the room has full state, or the room is partial stated,
but the server we joined off told us that there are no servers in the
room.

The `parse_enum` helper pulls an enum value from the query string
(by delegating down to the parse_string helper with values generated
from the enum).
This is used to pull out "f" and "b" in most places and then we thread
the resulting Direction enum throughout more code.
The previous assumption was that the stream_id column was unique
(for a room ID, receipt type, user ID tuple), but this turned out to be
incorrect.
Now find the max stream ID, then map this back to a database-specific
row identifier and delete other rows which match the (room ID, receipt type,
user ID) tuple, but *not* the row ID.
* Perfer `type(x) is int` to `isinstance(x, int)`
This covered all additional instances I could see where `x` was
user-controlled.
The remaining cases are
```
$ rg -s 'isinstance.*[^_]int'
tests/replication/_base.py
576: if isinstance(obj, int):
synapse/util/caches/stream_change_cache.py
136: assert isinstance(stream_pos, int)
214: assert isinstance(stream_pos, int)
246: assert isinstance(stream_pos, int)
267: assert isinstance(stream_pos, int)
synapse/replication/tcp/external_cache.py
133: if isinstance(result, int):

synapse/handlers/appservice.py
262: assert isinstance(new_token, int)
synapse/config/_util.py
62: if isinstance(p, int):
```
which cover metrics, logic related to `jsonschema`, and replication and
data streams. AFAICS these are all internal to Synapse
* Changelog
MSC3952 defines push rules which searches for mentions in a list of
Matrix IDs in the event body, instead of searching the entire event
body for display name / local part.
This is implemented behind an experimental configuration flag and
does not yet implement the backwards compatibility pieces of the MSC.
The `/relations` endpoint was not properly handle "live tokens"
(i.e sync tokens), to do this properly we abstract the code that
`/messages` has and re-use it.

On startup, the `_device_list_id_gen` stream id generator is initialized
using the maximum stream id seen in a list of tables. When we started
populating the `device_list_remote_pending` table in #13913, we forgot
to add it to the aforementioned list of tables, so the stream id
generator can hand out old stream ids after a restart. The end result is
that Synapse can fail to handle device list update EDUs after a restart
when a partial state join is in progress.
Add the `device_list_remote_pending` table to the list of tables to
consider when initializing the `_device_list_id_gen` stream id generator.

* Request partial joins by default
This is a little sloppy, but we are trying to gain confidence in faster
joins in the upcoming RC.
Admins can still opt out by adding the following to their Synapse
config:
```yaml
experimental:
faster_joins: false
```
We may revert this change before the release proper, depending on how
testing in the wild goes.
* Changelog
* Try to fix the backfill test failures
* Upgrade notes
* Postgres compat?
* Allow `AbstractSet` in `StrCollection`
Or else frozensets are excluded. This will be useful in an upcoming
commit where I plan to change a function that accepts `List[str]` to
accept `StrCollection` instead.
* `rooms_to_exclude` -> `rooms_to_exclude_globally`
I am about to make use of this exclusion mechanism to exclude rooms for
a specific user and a specific sync. This rename helps to clarify the
distinction between the global config and the rooms to exclude for a
specific sync.
* Better function names for internal sync methods
* Track a list of excluded rooms on SyncResultBuilder
I plan to feed a list of partially stated rooms for this sync to ignore
* Exclude partial state rooms during eager sync
using the mechanism established in the previous commit
* Track un-partial-state stream in sync tokens
So that we can work out which rooms have become fully-stated during a
given sync period.
* Fix mutation of `@cached` return value
This was fouling up a complement test added alongside this PR.
Excluding a room would mean the set of forgotten rooms in the cache
would be extended. This means that room could be erroneously considered
forgotten in the future.
Introduced in #12310, Synapse 1.57.0. I don't think this had any
user-visible side effects (until now).
* SyncResultBuilder: track rooms to force as newly joined
Similar plan as before. We've omitted rooms from certain sync responses;
now we establish the mechanism to reintroduce them into future syncs.
* Read new field, to present rooms as newly joined
* Force un-partial-stated rooms to be newly-joined
for eager incremental syncs only, provided they're still fully stated
* Notify user stream listeners to wake up long polling syncs

This creates a new store method, `process_replication_position` that
is called after `process_replication_rows`. By moving stream ID advances
here this guarantees any relevant cache invalidations will have been
applied before the stream is advanced.
This avoids race conditions where Python switches between threads mid
way through processing the `process_replication_rows` method where stream
IDs may be advanced before caches are invalidated due to class resolution
ordering.
