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.
