Cross reference the superblock with the highest sequence number
to sysfs. If there is a device shown still active in the superblock,
mark it as 'missing'.

Previously we were reading old superblocks stuck in the cache.
Pass in O_DIRECT when opening the device. This requires that
the dest buffer be memaligned.
If we are unable to read the entire superblock then increase
the buffer and try again.
Also since we now have to alloc the sb, make sure it is freed
everywhere in bcacheadm.

list-cachesets now searches through all cache# symlinks
instead of iterating with i++. This is because bcache
doesn't immediately reuse a cache# symlink when a dev
gets removed.
