This removes the configuration flag & updates the identifiers to
use the stable version.

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.

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.

The `exact_event_property_contains` condition can be used to
search for a value inside of an array.

This specifies to search for an exact value match, instead of
string globbing. It only works across non-compound JSON values
(null, boolean, integer, and strings).

Copy the suppress_edits push rule from Beeper to implement MSC3958.

https://github.com/beeper/synapse/blame/9415a1284b1bfb558bd66f28c24ca1611e6c6fa2/rust/src/push/base_rules.rs#L98-L114

If the feature is enabled and the event has a `m.mentions` property,
skip processing of the legacy mentions rules.

Since pyo3-log is initialized very early in the Python start-up
it caches the state of the loggers before they're fully initialized
(and thus are essentially disabled). Whenever we reload the
logging configuration we now also tell pyo3-log to discard
any cached logging configuration it has; it will refetch the
current logging configuration from Python at the next point
it logs.

This fixes Rust log lines not appearing in the homeserver logs.

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.

* Re-enable some linting

* Newsfile

* Remove comment

ruff is a flake8-compatible Python linter written in Rust.
It supports the flake8 plugins that we use and is significantly
faster in testing.

Fixes #13655

This change uses ICU (International Components for Unicode) to improve boundary detection in user search.

This change also adds a new dependency on libicu-dev and pkg-config for the Debian packages, which are available in all supported distros.

* Support MSC1767's `content.body` behaviour in push rules

* Add the base rules from MSC3933

* Changelog entry

* Flip condition around for finding `m.markup`

* Remove forgotten import

* Add support for MSC3931: Room Version Supports push rule condition

* Create experimental flag for future work, and use it to gate MSC3931

* Changelog entry

MSC3772 has been abandoned.

Switches to the stable identifier for MSC3786 and enables it
by default.

This disables pushes of m.room.server_acl events.

This protects against the common mistake of failing to remember to rebuild Rust code after making changes.

Over time we've begun to use newer versions of mypy, typeshed, stub
packages---and of course we've improved our own annotations. This makes
some type ignore comments no longer necessary. I have removed them.

There was one exception: a module that imports `select.epoll`. The
ignore is redundant on Linux, but I've kept it ignored for those of us
who work on the source tree using not-Linux. (#11771)

I'm more interested in the config line which enforces this. I want
unused ignores to be reported, because I think it's useful feedback when
annotating to know when you've fixed a problem you had to previously
ignore.

* Installing extras before typechecking

Lacking an easy way to install all extras generically, let's bite the bullet and
make install the hand-maintained `all` extra before typechecking.

Now that https://github.com/matrix-org/backend-meta/pull/6 is merged to
the release/v1 branch.

Some properties were marked as RedisProtocol instead of ConnectionHandler,
which wraps RedisProtocol instance(s).

Upgrade mypy to 0.931, mypy-zope to 0.3.5 and fix new complaints.

Part of #9744

Removes all redundant `# -*- coding: utf-8 -*-` lines from files, as python 3 automatically reads source code as utf-8 now.
