/*
* There is a quirk in sd-bus that in some systems, it is unable to get the
* well-known names on the bus, so it cannot identify if an incoming signal,
* which uses the sender's unique name, actually matches the callback's matching
* sender if the callback uses a well-known name, in which case it just calls
* the callback and hopes for the best, resulting in false positives. In the
* case of NewIcon & NewAttentionIcon, this doesn't affect anything, but it
* means that for NewStatus, if the SNI does not definitely match the sender,
* then the safe thing to do is to query the status independently.
* This function returns 1 if the SNI definitely matches the signal sender,
* which is returned by the calling function to indicate that signal matching
* can stop since it has already found the required callback, otherwise, it
* returns 0, which allows matching to continue.
