Refactors the partition to use `Message<H>` backed by prefix/tail buffer. The prefix is an `copy-on-write` buffer, that aliases the tail, detaches itself on first mutable access. It replaces the `TwoHalves` design, by inlining it's internals and introducing `copy-on-write` for the prefix part. Previosuly the `prefix` didn't implement `copy-on-write`, rather performed an deep copy on `Clone`, but this made the storage reads into an `Message` problematic, as there is no way to guarantee uniqueness of the `tail` (If we read from the cache we are guaranteed atleast 2 owners -- the cache storage and `Message` itself). -- This is an automated message from the Apache Git Service.
