Mike O'Driscoll 1403920367 derp,types,util: use bufio Peek+Discard for allocation-free fast reads (#19067) ... Replace byte-at-a-time ReadByte loops with Peek+Discard in the DERP read path. Peek returns a slice into bufio's internal buffer without allocating, and Discard advances the read pointer without copying. Introduce util/bufiox with a BufferedReader interface and ReadFull helper that uses Peek+copy+Discard as an allocation-free alternative to io.ReadFull. - derp.ReadFrameHeader: replace 5× ReadByte with Peek(5)+Discard(5), reading the frame type and length directly from the peeked slice. Remove now-unused readUint32 helper. name old ns/op new ns/op speedup ReadFrameHeader-8 24.2 12.4 ~2x (0 allocs/op in both) - key.NodePublic.ReadRawWithoutAllocating: replace 32× ReadByte with bufiox.ReadFull. Addresses the "Dear future" comment about switching away from byte-at-a-time reads once a non-escaping alternative exists. name old ns/op new ns/op speedup NodeReadRawWithoutAllocating-8 140 43.6 ~3.2x (0 allocs/op in both) - derpserver.handleFramePing: replace io.ReadFull with bufiox.ReadFull.
