libsnapshot: Group CowOperations into clusters
This introduces clusters of CowOperations to the Cow Format, improving
reader performance by allowing many operations to be read at once.
When the header's cluster_ops is a nonzero value, operations will be
clumped into packs of that number, where the last op is a special
CowClusterOp, which points to the start of the next cluster. Each
cluster is immediately followed by it's data, with the footer following
at the end of the file.
cluster_ops must not be 1, as we must include a CowClusterOp in each
group.
