Parse out the dev name for list-cachesets --list-devs
This gives the dev path that will be needed for query-dev
to get the superblock

bcacheadm is a combination of make-bcache, probe-bcache, bcache-super-show, and bcachectl(register).

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.

Move make-bcache, probe-bcache, and bcache-super-show functions into a
static library called libbcache.

the devices in the super-block.
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.

thie enables building it in a different directory, more
flexible install and configure options, and should make it
easier to eventualy create deb and rpm packages. Additionally
this makes it much easier to build and test this package
as it now behaves the same way as others we are using.
Move the rule to run a bit later, after
the standard udev rules have called blkid.
Don't run blkid manually, and run probe-bcache
as a fallback which can be patched out in a
package that depends on util-linux 2.24+.
probe-bcache: bail if libblkid finds anything
Preserve our last-resort safety check here
in case earlier rules fail to call blkid.
Fail if the device has any leftover superblock or partition table label.
Add a --wipe-bcache flag to overwrite bcache superblocks and recommend
wipefs for non-bcache superblocks.
Once the device is safe to write, always zero immediately before the
bcache superblock.
Make sure errors go to stderr. Use pkg-config.
