For large messages this generates far less garbage than ioutil.ReadAll(). Implement for gzip - RFC1952 requires it, and the Go implementation checks it already (modulo 2^32). Signed-off-by: Bryan Boreham <bjboreham@gmail.com>

Return -1 instead of an error in the case that we can't determine a size. Use a LimitReader set to size+1 so we can detect cases like corrupt messages and overflow of the 32-bit size field. Signed-off-by: Bryan Boreham <bryan@weave.works>
