Emitted when a D-Bus peer is trying to change the debug settings and used to determine if that is authorized.
This signal is emitted in a dedicated worker thread, so handlers are allowed to perform blocking I/O. This means that, for example, it is appropriate to call `polkit_authority_check_authorization_sync()` to check authorization using polkit.
If false is returned then no further handlers are run and the request to change the debug settings is rejected.
Otherwise, if true is returned, signal emission continues. If no handlers return false, then the debug settings are allowed to be changed.
Signal handlers must not modify invocation, or cause it to return a value.
The default class handler just returns true.
