Allow fileconflict if unowned file moving into backup array
The bulk of this commit is adding new tests to ensure the new behavior works without disrupting old behavior. This is a relatively sane maneuver when a package adds a conf file (e.g. '/etc/mercurial/hgrc') that was not previously in the package, but it is placed in the backup array. In essence, we can treat the existing file as having always been a part of the package and do our normal compare/install as pacnew logic checks. Signed-off-by: Dan McGee <dan@archlinux.org>
