CHANGES:
- Add host and subnet Seq.t iterators for Ipaddr.V4.prefix, Ipaddr.V6.Prefix
and Ipaddr.Prefix (#107 @verbosemode @dinosaure) - Ipaddr.V4.compare: use Int32.unsigned_compare, as provided since OCaml 4.08
(#118 @reynir) - Ipaddr.V6.t is a string, not a byte vector anymore (so it is immutable)
(#119 @reynir, restoring 4.08 compatibility #121) - Provide Ipaddr.Prefix.address (since 5.0.0, Ipaddr.V4.Prefix.address and
Ipaddr.V6.Prefix.address have been provided, but Ipaddr.Prefix.address was
forgotten) (#122 @hannesm) - Fix further docstrings (#123, fixes #81, @hannesm @reynir)
