bcacheadm capacity -u UUID --devs
Device Name Capacity (512 Blocks) Free (512 Blocks)
/dev/sdb 1048576.00 1024128.00
/dev/sdc 1048576.00 1024128.00
/dev/sdd 1048576.00 1024128.00

This is needed since libbcache expects an array of bucket sizes to be passed in. This is just so the tests can continue to use make-bcache until we can change them over to bcacheadm.

bcache.h: Bring version information to the latest kernel version.
bcache-super-show.c: Add setsize for caching devices. This indicates
the number of devices in caching set.
Testing done:
1.0 make-bcache with --label option and checking back to see if
bcache-super-show shows the devices.
2.0 bcache-super-show does not bail if version is 5.
3.0 bcache-super-show shows the correct setsize.
