Release 3.5.0
* Derive `Hash` for MessageType so it can be used as a key in hashmaps.
* Add API to represent match rules. These are used to subscribe to signals
mainly.
* Add `fdo::DBusProxy::{add_match_rule,remove_match_rule}`, that are
`{add_match,remove_match}` replacements that make the same
underlying D-Bus calls but make use of the new `MatchRule` type. We also
deprecate the `{add_match,remove_match}` to discourage use of these less
type-safe versions.
* `ProxyBuilder::uncached_properties` sets given list Instead of
appending. The usecase is for users to set it only once.
* `ObjectServer` should handle methods destined to unknown names if no
names are registered. We were only doing this for p2p case but we should
do this for bus case well. Otherwise it breaks things for folks who were
using `fdo::DBusProxy::request_name` along with `ObjectServer` for any
reason.
* Bump zvariant requirement to latest release.
*
