cluster/ec: add separate versions for data/entry, metadata
Adding 64 bits in "version" key of extended attributes. First 64 bits (Left)
represents Data version. Last 64 bits (right) represents Meta Data version.
Note: 3.7 and 3.6 version ec can't co-exist with this change because xattrop in
3.6 will fail with ERANGE as the buffer passed to it will be '8' bytes where as
the value will be 16 bytes in 3.7. Where as 3.7 version clients can work with
old version files. For upgrades we need to tell users to complete heals and
then upgrade
