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.

prints the device capacity, and free space for a cacheset
example:
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
Total 3145728.00 3072384.00
Also did some bcacheadm stats refactoring.

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.
