Ting-Yu Wang c0f21bb19a pkg/buffer: Reorganize internal structure to allow dynamic sizes. 
This change changes `buffer.data` into a `[]byte`, from `[bufferSize]byte`.
In exchange, each `buffer` is now grouped together to reduce the number of
allocation. Plus, `View` now holds an embeded list of `buffer` (via `pool`) to
support the happy path which the number of buffer is small. Expect no extra
allocation for the happy path.

It is to enable the use case for PacketBuffer, which
* each `View` is small (way less than `defaultBufferSize`), and
* needs to dynamically transfer ownership of `[]byte` to `View`.
  (to allow gradual migration)

This also adds substantial test cases.

The Read/Write interfaces are dropped as they are not necessary.
