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.
