squashfs-tools being updated in rawhide

Phillip released 4.5 which has some new functionallity, some clean up and some bug fixes. It looks like he worked pretty hard on it for about the last 6 months. I don't think that the new functionallity will break any of our normal stuff, but if something breaks that uses it, that would be a good possibility to check out. The man pages are currently still out of date, but you can use the program's help to get up to date documentation. I had a successfull build after tonight's compose started, so the earliest it will show up in rawhide is Saturday morning (in the US), assuming no one off rawhide composes.
