* Fixes#3837
* Change objects to use DBusMgr rather than separate adaptors
- Update all DBus invokable methods to new parameter order
- Change all usage of DBusReturn to simpler DBusResult
- Use DBusMgr to handle path and service registration
- Remove adaptor/*
- Set path in DBusObject
- Unregister service when service is destroyed
- Restore handling of invalid QVariant in prompt complete signal
- Clean up meta type registration
- Move dbus related file together
- Convert to QSharedPointer as much as possible
- Fix mapping of the Delete method
- Handle dbus property get all
* Add per-client states
- Move cipher negotiation to DBusClient
- Show list of clients instead of sessions in the settings page
- Add settings for confirmation of accessing items
- Fix infinite recursion when client disconnected
- Use optional explicit DBusClient parameter instead. This makes accessing
the client info in an async context explicit, and thus prevent accidental
assertions in prompts.
* Improve User Interface
- Add per-item access confirmation (if enabled)
- Remove the "disable for site" button for the access control dialog
- Improve the text on the settings page to be more consistent
- Fix disconnect buttons in settings page not working
- Make the unlock prompt method nonblocking
* Fix and cleanup unit tests
- Use QTRY_COMPARE when checking signal spies, as dbus signals are threaded
- Fixes in meta type registration and type conversion
- Remove QStringLiteral in COMPARE macros, making diff output readable
- Add testing for remembering auth decision
