new btrfs-progs needs testing and karma

[Chris Murphy]

btrfs-progs-0.20.rc1.20131114git9f0c53f-1.fc20 incorporates 16KB leafsize/nodesize by default, which significantly reduces metadata fragmentation and improves performance. Since this is set at the time the file system is created, it would be nice to get this in before freeze. Since it's the new default, it's considered safe.

There is one minor regression found, which is 'btrfs filesystem show' reports duplicate volumes. A fix is committed upstream already and a post-install update will fix this.
