This PR refactors the way we use buffers for O_DIRECT and to re-use those buffers for messagepack reader writer. After some extensive benchmarking found that not all objects have this benefit, and only objects smaller than 64KiB see this benefit overall. Benefits are seen from almost all objects from 1KiB - 32KiB Beyond this no objects see benefit with bulk call approach as the latency of bytes sent over the wire v/s streaming content directly from disk negate each other with no remarkable benefits. All other optimizations include reuse of msgp.Reader, msgp.Writer using sync.Pool's for all internode calls.
