1. Refactor Bytes to use an internal vtable …

   Bytes is a useful tool for managing multiple slices into the same region
   of memory, and the other things it used to have been removed to reduce
   complexity. The exact strategy for managing the multiple references is
   no longer hard-coded, but instead backing by a customizable vtable.
   
   - Removed ability to mutate the underlying memory from the `Bytes` type.
   - Removed the "inline" (SBO) mechanism in `Bytes`. The reduces a large
     amount of complexity, and improves performance when accessing the
     slice of bytes, since a branch is no longer needed to check if the
     data is inline.
   - Removed `Bytes` knowledge of `BytesMut` (`BytesMut` may grow that
     knowledge back at a future point.)
