> Arrow currently has a hard dependency on Netty and exposes this in public 
> APIs. This shouldn't be the case. There could be many allocator 
> implementations with Netty as one possible option. We should remove hard 
> dependency between arrow-vector and Netty, instead creating a trivial 
> allocator. ArrowBuf should probably expose an <T> T unwrap(Class<T> clazz) 
> method instead to allow inner providers availability without a hard 
> reference. This should also include drastically reducing the number of 
> methods on ArrowBuf as right now it includes every method from ByteBuf but 
> many of those are not very useful, appropriate.
> This work should come after we do the simpler ARROW-3191
