I noticed List::Util 1.45+ includes a new "uniq()" sub, but
that's only distributed with Perl as of 5.26+.
Since we care about supporting older versions of Perl, I still
took the opportunity to simplify some of our own similar logic
for making things unique. It turns out only Inbox->nntp_url
really benefits from List::Util::uniq at the moment, but there's
some small simplifications to be had along the way.
Eric Wong (6):
contentid: use map to generate %seen for Message-Ids
nntp: simplify setting X-Alt-Message-ID
inbox: simplify filtering for duplicate NNTP URLs
mid: shorten uniq_mids logic
wwwstream: shorten cloneurl uniquification
contentid: ignore duplicate References: headers

This use of map {} is a common idiom as we no longer consider
the Message-ID as part of the digest.
