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

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
