Bug#864910: jessie-pu: package debconf/1.5.56+deb8u1

[Colin Watson <cjwatson@debian.org>]

Package: release.debian.org
Severity: normal
Tags: jessie
User: release.debian.org@packages.debian.org
Usertags: pu

I'd like to cherry-pick the fix to #863479 into jessie in order to
reduce stderr noise in upgrades to stretch.  The single commit on top of
the current version in jessie follows.  I've left it as UNRELEASED for
the time being pending advice on whether I should put stable or
oldstable in the changelog given what date it is ...

commit c2f59e3fe49ef72cf575ff65da8aedae54ac10e5
Author: Niko Tyni <ntyni@debian.org>
Date:   Sun May 21 13:25:38 2017 +0300

    Use File::Temp instead of the deprecated POSIX::tmpnam() in Debconf::TmpFile
    
    File::Temp is in perl-base since jessie, so using it here should be fine.
    
    We no longer need to handle the sysopen() part ourselves.
    
    [Amended by Colin Watson to bump Pre-Depends on perl-base.]
    
    Closes: #863071
