1. add handle HandleStreamingReader …

   This commit introduces a new type 'StreamingReadResponse' which
   implements the io.Writer interface. Thus users are writing into the
   response rather than updating the Data property of ReadResponse. This
   allows us to preallocate the space for the whole message and therefore
   reduce allocations. Additionally we may now use a sync.Pool to manage
   the required space needed for the read request and further minimize
   allocations.
   
   This patch intends to not break existing implementations of the
   fuse.HandleReader interface by introducing a new interface that provides
   the advantages described above.
   
   I've benchmarked this using a scenario that is similar to the
   environment I need for the application I am currently developing. The
   benchmark reads data blobs of different sizes from the solid-state
   drive. Using this patch we can achieve a 1.60x speed up as well as
   reduce memory allocations by 85%.
