List if User IDs

[Bernhard Herzog]

How do I determine the list of user IDs associated with a key? The key
struct has a glist member called uids but there doesn't seem to be an
API function to access it (even worse, a quick grep seems to indicate
that it's freed but never initialized!). Furthermore there doesn't seem
to be a way to find out which signatures belong to which user id.
