Subject: make GetLocalitySortedVersionSet more generic
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

No reason in and of by itself at the moment, but prepares for the goal
of having 'apt search' and 'apt-cache search' using the same code now
that they at least support the same stuff. The 'apt' code is just a
multitude slower at the moment…
