build(deps): update zbus requirement from 3.6 to 4.2 in /ladspa

[dependabot]

Updates the requirements on zbus to permit the latest version.

Release notes

Sourced from zbus's releases.

🔖 zbus 4.2.0

• ✨ Make spawning tasks for method call handling, optional. dbus_interface now provides a spawn attribute to control whether the method call handling is spawned as a task or not.
• ✨ Add serial to Message's Debug representation.
• 🔌 Add connection::Builder::authenticated_socket for creating a connection with a pre-authenticated socket. This could also be socket that doesn't need any authentication. #590.
• ✨ Add connection::socket::{ReadHalf::receive_message, WriteHalf::send_message} methods. These method have a default implementation that just uses the lower-level sibling methods. Implementers can either override this method or the lower-level method, depending on the underlying socket they're using.
• ✨ Introducing connection::socket::Channel. This new socket type, uses channels for in-process p2p communication. This can be used with connection::Builder::authenticated_socket to create a connection for in-process communication. #591.
• ⚡️ Pipeline client-side handshake as much as possible, including the Hello method call to the bus. This reduces unnecessary round-trips & hence latencies. #493
• ✨ Add connection::Builder::auth_mechanism. Unlike auth_mechanisms method, this method only allows one mechanism to be set.
• 🗑️ Deprecate connection::Builder::auth_mechansims. In favor of auth_mechansim. This is in preparation for #731, when we will remove this method entirely.
• 🥅 Don't assert on invalid serve_at() usage. Document that standard interfaces are already added. Return an error instead of an explicit panic if attempted, since it is not an internal invariant.
• 🥅 Catch interface handler error.
• 🔊 Reduce the amount of tracing data when adding traces in handlers (duplicated "msg").
• 🔥 Remove now unnecessary hack to ensure ObjectManager signals aren't sent before Hello method.
• 🔊 Instrument all async methods of server handshake.
• 🚩 Support autolaunch address on Windows without windows-gdbus feature and associated hacks. Turns out that the reference D-Bus implementation supports autolaunch fine and we don't need special support for gdbus binary. Hopefully, in the near future, busd will also support it. #687
• 📝 Clearly document Interface being unstable API. Also recommend what people should do when dbus_interface isn't enough.
• 🔥 Drop impossible scope on autolaunch session bus address. We currently can't handle scopes on autolaunch addresses so there is no need to create an address with scopes.
• 🥅 Correctly handle cancellation of handshake in server. If the client sends a CANCEL command during a handshake, the server must move on to the next handshake method available (if any).
• 🛂 Server-side handshake should be as lenient as the spec says. If a received command from the client is unknown or invalid in the current context, we shouldn't completely error out but rather send an error and continue as if nothing happened.
• 🔊 Exclude newline terminators from String repr of commands. Otherwise it messes up the logging output.
• 🏷️ Implement Default for address::transport::Autolaunch.
• 🚨 Remove duplicate trait bounds.
• 💄 Use the new logo in docs.
• ⬆️ Updated depdencies:
  • blocking to 1.6.0
  • async-fs to 2.1.2
  • async-task to 4.7.1
  • async-process to 2.2.2
  • async-executor to 1.11.0
  • async-trait to 0.1.80
  • vsock to 0.5.0
