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

This does nothing and I want to remove it from the MSC.

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.

* Correct the push rule IDs.
* Removes the sound tweak for room notifications.

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.

* 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 MSC1767's dedicated room version, based on v10

* Only enable MSC1767 room version if the config flag is on

Using a similar technique to knocking:

* Support MSC3932: Extensible events room version feature flag

* Changelog entry

* 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.
