Comment # 10 on bug 1086447 from Luciano Santos

If there's no objections I will forward my changes to Factory. Now when issuing
`zypper in udisks2` these are the dependency chain we get:  

libbd_btrfs2 libbd_crypto2 libbd_fs2 libbd_mdraid2 libbd_part2 libbd_swap2
libbd_utils2 libblockdev libblockdev2 libpipewire-0_1-0 libspa-lib0
libudisks2-0 libudisks2-0_btrfs udisks2  

libbd_btrfs2 plugin being recommended and the rest, required. I used Provides
tag for the plugins with the pattern "libblockdev-pluginname" now that they are
explicitly being required and they are standalone libraries as well.  

What do you think Thomas Blume?
