Title: #5361: negcache: multiple fixes
Nonetheless, I think patches are doing right things and should fix
both issues seen in https://bugzilla.redhat.com/show_bug.cgi?id=1828483#c4
: short name
treated as fqn resulting in unexpanded upn entries and missed name entries
(didn't yet test manually though).
Sorry it took that long. I finally verified that those patches resolves both issues seen
Covscan is clear.
With exception of one minor issue and a couple of mistypes, most of
my comments are merely questions to make sure I got things right or requests to clarify
Marking as "changes requested" to deal with this ^^.
