fix size-0 chunker bug

switch to go-buffer-pool

It has a nicer interface and we don't even need the rest of the msgio

Prereq for: https://github.com/libp2p/go-msgio/pull/9

gx publish 0.0.12

return err when rabin min less than 16

In general, it's easier for people to parse positive statements.
