Brian Goff 9a25b1d942 Improve performance/reduce allocs of bytespipe
Creates a `fixedBuffer` type that is used to encapsulate functionality
for reading/writing from the underlying byte slices.

Uses lazily-loaded set of sync.Pools for storing buffers that are no
longer needed so they can be re-used.
