Add a new reason field to pmconflict_t struct
Sometimes "foo conflicts with bar" information is not enough, see this thread: http://bbs.archlinux.org/viewtopic.php?id=77647. That's why I added a new reason field to our pmconflict_t struct that stores the packager- defined conflict that induced the fact that package1 conflicts with package2. I modified the front-end (in callback.c, sync.c, upgrade.c) to print this new information as well. Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu>
