Victor Hsieh 5c4e0347e1 Drain the read buffer of DevFuseReader ... In some circumstances, it's possible that the buffered data isn't fully consumed by the filesystem. Before handling the next request, we need to drain the residual. This change also moves the reader/writer/mapper out of the loop, since we intend to not duplicate the FDs for each interation, and prefer to reuse the buffer / avoid re-allocation anyway. This allows us to implement `drain` in DevFuseReader.
